This article presents a distinctive method of developing hydrophobic filaments for fused filament fabrication (FFF) of a hydrophobic mesh for oil-water separation. In this method, a modified solvent casting method is used to develop hydrophobic filaments for mesh fabrication. The fabrication process is achieved by integrating concentrations of hexadecyltrimethoxysilane (HDTMS) and polytetrafluoroethylene (PTFE) into a polylactic acid (PLA) slurry. In order to check the filament property, the filaments are characterized using water contact angle (WCA) measurements, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermal gravimetric analysis (TGA). The observations revealed that incorporating HDTMS and PTFE into PLA significantly enhances the filament’s hydrophobic properties by altering their microstructure. An optimal water contact angle of 125.76° is achieved with 2 g PLA + 0.2 mL HDTMS + 1 mL PTFE. Further, the SEM analysis showed that adding HDTMS and PTFE improves the surface properties by reducing voids, thereby enhancing the hydrophobicity. Furthermore, the addition of HDTMS and PTFE also improves the thermal and mechanical properties of the filaments. The current filament is expected to function as an oil-water separation mesh, which will be used in both commercial and domestic devices.

本文介绍了一种独特的疏水网油-水分离熔丝（FFF）制备疏水丝的方法。在这种方法中，采用一种改进的溶剂铸造方法来开发用于制造网格的疏水长丝。制造工艺是通过将十六烷基三甲氧基硅烷（HDTMS）和聚四氟乙烯（PTFE）的浓度整合到聚乳酸（PLA）浆料中来实现的。为了检查长丝的性能，使用水接触角（WCA）测量、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和热重分析（TGA）对长丝进行了表征。结果表明，将HDTMS和PTFE掺入PLA中，通过改变其微观结构，显著提高了其疏水性能。最佳水接触角为125.76°，实现2g PLA + 0.2 mL HDTMS + 1 mL PTFE。此外，SEM分析表明，HDTMS和PTFE的加入通过减少空隙来改善表面性能，从而提高疏水性。此外，HDTMS和PTFE的加入也改善了长丝的热性能和力学性能。目前的长丝有望作为油水分离网，将在商业和家用设备中使用。

Rubber is a type of important evidence in forensic cases, for example, in traffic accident cases. It can help identify or exclude suspected vehicles by analyzing and comparing rubber evidence left on site when the vehicle brakes with the samples from suspected vehicles. In many other cases, rubber products are also important investigative clues because of their widespread application in daily life. Currently, there are 10 types of rubber popularly used in China. Infrared spectroscopy can effectively distinguish the 10 types of rubber. However, only comparing the shapes of infrared spectra from the samples left on sites and from suspected samples generates risks in differentiation, as some weak characteristic peaks are easily overlooked, leading to misjudgment in forensics. It is necessary to have a clear understanding of these characteristic peaks and their chemical bond assignments to achieve identification more effectively and quickly. So, the main and auxiliary indicative peaks were summarized and interpreted. The results showed that infrared can provide safer and more reliable detection results in cases; the assignments of the peaks also added basic information and would be helpful to future microplastics studies.

橡胶是法医案件中的一种重要证据，例如交通事故案件。它可以通过分析和比较车辆刹车时留在现场的橡胶证据与可疑车辆的样本来帮助识别或排除可疑车辆。在许多其他案件中，橡胶制品也因其在日常生活中的广泛应用而成为重要的调查线索。目前，在中国广泛使用的橡胶有10种。红外光谱可以有效区分10种橡胶。然而，仅将现场遗留样品的红外光谱形状与疑似样品的红外光谱形状进行比较，存在区分风险，容易忽略一些较弱的特征峰，导致法医误判。有必要清楚地了解这些特征峰及其化学键分配，以便更有效、更快速地进行鉴定。因此，对主要指示峰和辅助指示峰进行了总结和解释。结果表明，红外在某些情况下可以提供更安全可靠的检测结果；峰的分配也增加了基本信息，对未来的微塑料研究有帮助。

The objective of this study is to enhance the thermal as well as the mechanical properties of vulcanized natural rubber with hybrid reinforcement including alkali-treated cotton fiber and carbon black. The central composite design and response surface methodology techniques were employed to design the experiment and examine optimum mechanical strength with corresponding optimum reinforcement composition. The tensile strength of composites increased from 1.71 to 18.87 MPa as a result of reinforcement. Likewise, the tear strength was improved from 23.20 to 57.91 N/mm. The thermal stability of the composites gets enhanced with the addition of carbon black from 320 °C to 343 °C. FTIR and SEM analysis revealed intercomponent interactions and surface texture of prepared composites. The hybrid reinforcement of cotton fiber and carbon black in the rubber matrix brings out enhancement in mechanical properties as well as the thermal stability of the final composite material. A minute increment in the density of samples was noticed with the addition of cotton fiber and carbon black in the rubber matrix. This increase in density is significantly less than the increase in mechanical strength of composites, which is a good parameter for application purposes of composites.

Polymer gels have presently been employed instead of cotton wool soaked with organic solvents to clean artwork in cultural heritage restoration since they are less harmful to the artwork’s surface and more efficient in safe cleaning. A lack of insight into the characteristics and properties of polymer gels produced by various materials and methods leads to misuse and might cause damage to artwork. In this work, poly(vinyl alcohol) (PVA) was employed to produce a cleaning gel. Different crosslinking agents, sodium tetraborate (borax), borax plus polyethylene glycol (borax-PEG), and glutaraldehyde, were studied together with various gel formation methods, solely casting, casting plus freeze-thawing, and casting plus freeze-thawing and solvent soaking. Characterization and property tests were carefully conducted to understand the behavior of produced materials. The porosity of the PVA gel crosslinked with borax-PEG significantly increased by freeze-thawing. After being loaded with water, the porous structure was maintained even as it swelled, and its confined water was slowly released when the gel was left on an oil painting. The 4 wt% PVA gel crosslinked with 5% borax and 0.5% PEG, after freeze-thawing and water soaking, exhibited the most suitable rigidity and elasticity for the required cleaning gel properties and provided better cleaning efficiency on oil paintings than other gels. These results indicated that PVA crosslinked with borax plus PEG and formed by the casting plus freeze-thawing and solvent soaking could be an alternatively suitable material for a cleaning gel in oil-painting restoration.

由于聚合物凝胶对艺术品表面的伤害更小，安全清洁效率更高，因此目前在文物修复中使用聚合物凝胶来代替浸有有机溶剂的棉絮来清洁艺术品。缺乏对各种材料和方法生产的聚合物凝胶的特性和性质的了解导致误用，并可能导致艺术品的损坏。在这项工作中，聚乙烯醇（PVA）被用于生产清洁凝胶。研究了四硼酸钠（硼砂）、硼砂加聚乙二醇（硼砂- peg）和戊二醛等不同交联剂的凝胶形成方法，分别为单纯铸造、铸造加冻融、铸造加冻融和溶剂浸泡。仔细进行了表征和性能测试，以了解生产材料的行为。冻融后硼砂-聚乙二醇交联的聚乙烯醇凝胶孔隙率显著提高。在装满水后，即使膨胀，多孔结构也保持不变，当凝胶留在油画上时，其封闭的水会慢慢释放出来。与5%硼砂和0.5% PEG交联的4wt % PVA凝胶经冻融和水浸泡后，其刚性和弹性最适合所需的清洁凝胶性能，对油画的清洁效果优于其他凝胶。结果表明，PVA与硼砂+ PEG交联，经浇铸+冻融和溶剂浸泡形成的PVA可作为油画修复中清洁凝胶的替代材料。

Thermoplastic pipes made from chlorinated polyvinyl chloride (CPVC) can undergo varying degrees of degradation due to extreme fluctuations in pressure and temperature. This underscores the importance of controlling their mechanical properties and identifying potential failures before they occur. The present research focuses on evaluating damage in CPVC pipes using deterministic methods, such as damage and reliability analysis. To assess the degradation of these pipes, experimental tests were conducted to determine the mechanical factors influencing their performance. Specifically, burst pressures and times were recorded during the tests. Additionally, analytical damage models were developed based on modified and simplified versions of the unified stress and strain theory, static damage models, and the unified theory of damage. By applying the principles of the unified damage theory, the evolution of life fractions as a function of burst pressures was tracked for both blank and notched pipes.

由氯化聚氯乙烯（CPVC）制成的热塑性管道由于压力和温度的极端波动会发生不同程度的降解。这强调了控制其机械性能和在故障发生之前识别潜在故障的重要性。目前的研究重点是利用确定性方法，如损伤分析和可靠性分析，对CPVC管道进行损伤评估。为了评估这些管道的退化，进行了实验试验，以确定影响其性能的机械因素。具体来说，在测试过程中记录了爆炸压力和时间。此外，基于统一应力应变理论、静态损伤模型和统一损伤理论的修正和简化版本，建立了分析损伤模型。应用统一损伤理论的原理，对空白管和缺口管的寿命分数随破裂压力的变化规律进行了研究。

Two novel donor–acceptor copolymers, CDTBT-T and CDTBT-biT, were synthesized via the Stille coupling reaction. Both copolymers incorporate 4,4-bis(4-hexylphenyl)-4H-cyclopentadithiophene (the electron-rich segment) and octyloxy-substituted benzo[c][1, 2, 5]thiadiazole (the electron-deficient segment), where these two segments were linked by either thiophene or bithiophene units as π-bridges. CDTBT-T and CDTBT-biT were designed as donor materials for use in bulk-heterojunction polymer solar cells (PSCs). UV-Vis absorption spectra revealed that CDTBT-T and CDTBT-biT covered broad absorption ranges from 400 to 800 nm with medium optical band gaps of 1.71 eV and 1.74 eV, respectively, which are well-matched with the solar spectrum. Based on cyclic voltammetry, CDTBT-T exhibited a slightly lower HOMO level (–5.10 eV) compared to CDTBT-biT (–5.02 eV), reflecting the slightly stronger electron-donating nature of the bithiophene spacer in CDTBT-biT relative to the single thiophene spacer in CDTBT-T. Both polymers showed good thermal stabilities, as shown from thermogravimetric studies. The XRD analysis revealed that the bithiophene-containing polymer, CDTBT-biT, demonstrated sharper diffraction peaks and formed a more closely packed structure in the solid state. These results demonstrate the potential of CDTBT-T and CDTBT-biT as superior p-type materials for the development of high-efficiency PSCs.

通过Stille偶联反应合成了两种新型的供体-受体共聚物CDTBT-T和CDTBT-biT。这两种共聚物都含有4,4-二（4-己基苯基）- 4h -环戊二噻吩（富电子段）和辛氧基取代苯并[c][1,2,5]噻二唑（缺电子段），其中这两个段由噻吩或二噻吩单元作为π桥连接。设计了CDTBT-T和CDTBT-biT作为供体材料用于块状异质结聚合物太阳能电池（PSCs）。紫外可见吸收光谱显示，CDTBT-T和CDTBT-biT覆盖了400 ~ 800 nm的较宽吸收范围，中光学带隙分别为1.71 eV和1.74 eV，与太阳光谱匹配良好。基于循环伏安法，CDTBT-T的HOMO能级（-5.10 eV）略低于CDTBT-biT (-5.02 eV)，这反映了CDTBT-biT中双噻吩间隔层相对于CDTBT-T中的单噻吩间隔层具有稍强的给电子性质。热重研究表明，这两种聚合物都具有良好的热稳定性。XRD分析表明，含噻吩聚合物CDTBT-biT在固体状态下具有更清晰的衍射峰和更紧密的排列结构。这些结果证明了CDTBT-T和CDTBT-biT作为开发高效psc的优越p型材料的潜力。

Natural fiber-reinforced composites have been increasingly developed over the past few decades due to their mechanical properties, which are comparable to synthetic fibers. Abaca fiber, as one of the natural fibers, possesses good mechanical strength and low density. Activated carbon, commonly used as an adsorbent particle, is also utilized as a filler in fiber-reinforced composites. This study aims to characterize the activated carbon synthesized from oil palm empty fruit bunches (OPEFB) and analyze the effect of adding activated carbon at variations of 0 wt%, 1 wt%, 2 wt%, 3 wt%, and 5 wt% on the tensile strength of epoxy/abaca composites. The composites were fabricated using the hand layup method followed by vacuum bagging. The characterization of the activated carbon showed high porosity with an amorphous structure and a porous surface area of 742 m²/g and a pore volume of 0.35 cm³/g. The use of 1 wt% activated carbon filler in epoxy/abaca composites resulted in the highest tensile strength (48.90 MPa). The decrease in tensile strength at higher filler content is attributed to poor dispersion of activated carbon particles, which weakens the interface between the matrix and abaca fibers. These findings highlight the potential of optimized activated carbon loading to enhance the mechanical properties of natural fiber-reinforced composites, particularly for applications in the automotive, construction, and aerospace industries.

天然纤维增强复合材料由于其机械性能可与合成纤维相媲美，在过去的几十年中得到了越来越多的发展。Abaca纤维是一种天然纤维，具有良好的机械强度和低密度。活性炭是一种常用的吸附颗粒，也可用作纤维增强复合材料的填料。本研究旨在表征由油棕空果串（OPEFB）合成的活性炭，并分析添加0 wt%、1 wt%、2 wt%、3 wt%和5 wt%的活性炭对环氧树脂/abaca复合材料抗拉强度的影响。复合材料的制备采用手铺法和真空装袋法制备。表征的活性炭具有较高的孔隙率，具有无定形结构，孔表面积为742 m2/g，孔体积为0.35 cm³/g。在环氧树脂/abaca复合材料中使用1 wt%的活性炭填料，其拉伸强度最高（48.90 MPa）。填料含量高时，拉伸强度降低的原因是活性炭颗粒分散性差，削弱了基体与abaca纤维之间的界面。这些发现强调了优化活性炭负载的潜力，以提高天然纤维增强复合材料的机械性能，特别是在汽车、建筑和航空航天工业中的应用。

2-Methoxyethyl acrylate draws significant interest for its exceptional biofilm-resistant properties, but its interaction with other monomers complicates outcome predictions during polymerization. To investigate these mechanisms, we synthesized biofilm-resistant prepolymers, HMEA and GMEA, using free radical polymerization (FRP). Gelation issues caused by the intramolecular crosslinking were mitigated by introducing styrene spacers, yielding a new set of additional prepolymers, HSMEA and GSMEA. Crosslinking with an aliphatic isocyanate (HDI) in the presence of a dibutyltin dilaurate (DTBDL) catalyst successfully formed urethane linkages, which were confirmed by attenuated total reflectance fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) analysis. Overall, this crosslinking significantly reduced the exposed OH groups and enhanced the hydrophobicity of the polymers. Both cGMEA and cGSMEA displayed exceptional antibiofouling behavior as demonstrated by their resistance to bovine serum albumin (BSA). Mechanical tests demonstrated superior properties with tensile strengths of 4.1 MPa and 3.6 MPa and impressive elongation strains of 223% and 425%, respectively. This work reports one of its kind 2-Methoxyethyl acrylate-based polymer consisting of reversible urethane bonds providing self-healing capabilities and enhanced durability as a coating material. However, further investigation into the underlying mechanisms of these synergistic effects will be critical to fully harness the potential of methoxyethyl acrylate-based polymers.

2-甲氧基乙基丙烯酸酯因其特殊的生物膜抗性特性而引起了人们的极大兴趣，但它与其他单体的相互作用使聚合过程中的结果预测复杂化。为了研究这些机制，我们利用自由基聚合（FRP）合成了抗生物膜预聚物HMEA和GMEA。通过引入苯乙烯间隔剂，缓解了分子内交联引起的凝胶化问题，产生了一组新的预聚物，hsma和gsma。在双酸二丁基锡（DTBDL）催化剂的存在下，与脂肪族异氰酸酯（HDI）交联成功地形成了聚氨酯键，并通过衰减全反射傅立叶变换红外（FTIR）光谱和差示扫描量热（DSC）分析证实了这一点。总的来说，这种交联显著减少了暴露的OH基团，增强了聚合物的疏水性。cGMEA和cgsma均表现出对牛血清白蛋白（BSA）的抗性。力学试验表明，其抗拉强度分别为4.1 MPa和3.6 MPa，延伸率分别为223%和425%。本研究报告了一种基于2-甲氧基乙基丙烯酸酯的聚合物，该聚合物由可逆的聚氨酯键组成，具有自修复能力和增强的耐用性，可作为涂层材料。然而，进一步研究这些协同效应的潜在机制对于充分利用丙烯酸甲氧基乙酯基聚合物的潜力至关重要。

Gel Permeation Chromatography (GPC) and Fourier-Transform Infrared Spectroscopy (FTIR) are two powerful analytical techniques that have been used in polymer chemistry for decades. GPC can separate polymers based on their molecular weights, while FTIR can identify the functional groups present in the macromolecular chain. The main benefit of coupling GPC and FTIR is that they complement each other to provide a deeper insight into the molecular weight distribution and chemical composition of challenging polymers. Although over the last 60 years sporadic papers have been published on coupling the GPC with FTIR using a flow cell, the method has not gained widespread acceptance. This was largely due to the challenges associated with creating an interface to effectively combine both techniques without compromising their performance. Furthermore, the studies were done on in-house built instruments using components from various providers, as none of the major analytical laboratory equipment manufacturers had a specific program in place to support the development of GPC-FTIR technology. Here we present the development of a GPC-FTIR instrument based exclusively on Agilent Technologies components, with an improved design of the flow cell aimed at boosting signal-to-noise ratio and minimizing peak width. The system’s performance was evaluated by analyzing polymethylmethacrylate (PMMA) samples with narrow and broad molecular weight distributions.

凝胶渗透色谱（GPC）和傅里叶变换红外光谱（FTIR）是几十年来在聚合物化学中应用的两种强大的分析技术。GPC可以根据分子量分离聚合物，而FTIR可以识别大分子链上存在的官能团。结合GPC和FTIR的主要好处是它们可以相互补充，从而更深入地了解具有挑战性的聚合物的分子量分布和化学成分。虽然在过去的60年里，已经有零星的论文发表了使用流动池将GPC与FTIR耦合起来，但这种方法并没有得到广泛的接受。这主要是由于创建一个接口来有效地结合这两种技术而不影响其性能所带来的挑战。此外，由于主要的分析实验室设备制造商都没有专门的计划来支持GPC-FTIR技术的发展，因此研究是在内部制造的仪器上完成的，使用了来自不同供应商的组件。在这里，我们介绍了一种完全基于安捷伦技术组件的GPC-FTIR仪器的开发，其流池的改进设计旨在提高信噪比和最小化峰宽。通过分析分子量分布较窄和较宽的聚甲基丙烯酸甲酯（PMMA）样品来评价该系统的性能。

Poly methyl methacrylate (PMMA) is the most often used acrylic for partial and full dentures. Denture fractures are induced by fatigue as a result of repeated masticatory, flexural, and impact stresses. PMMA’s remarkable qualities, such as beauty, cost-effectiveness, ease of manipulation, low density, and tunable mechanical properties, make it an ideal option for use in dentistry. The durability of pure PMMA is improved by incorporating appropriate weight percentages of nano reinforcement of ceramic material. The doping of nano-reinforcement materials enhances the tensile strength, compressive strength, micro-hardness; flexural strength, yield strength, impact strength, transverse strength, thermal expansion coefficient and decreases water sorption of PMMA composites investigated by different researchers. This study explores how the biopolymer matrix (PMMA) is affected by aluminum oxide (Al₂O₃), zirconium oxide (ZrO₂), and titaniun dioxide (TiO₂) reinforcements in terms of mechanical, physical, and tribological characteristics of PMMA dental composites. Additionally, the applications of polymer- based composites are explored.
