Endeavors have been made to construct new donor-acceptor (D-A) monomers utilizing 9 H-carbazole (CB) as electron donors and different electron acceptors. All estimations were finished using DFT and TD-DFT, and B3LYP level with a 6-311 G basis set in the gas and chloroform solvent. The impacts of the distinctive acceptors on the geometry of molecules and optoelectronic properties of these D-A monomers were discussed to dissect the connection connecting the molecular structures and the optoelectronic properties. Likewise, the HOMO - LUMO energies, atomic orbital densities are calculated theoretically. Notwithstanding the charge transfer measure between the carbazole electron donor unit and the electron acceptor one is upheld by breaking down the optical spectra of the acquired monomers and the restriction of involved HOMO and LUMO. The outcomes show that the D-A monomers, CB-ODP, CB-TDP, and CB-SDP, are acceptable for optoelectronic applications in organic solar cells like BHJ.

利用9个h -咔唑(CB)作为电子给体和不同的电子受体,构建了新的给体-受体(D-A)单体。所有的估计都是用DFT和TD-DFT完成的,B3LYP水平在6-311 G的基础上设置在气体和氯仿溶剂中。讨论了不同受体对这些D-A单体分子几何结构和光电子性能的影响,剖析了分子结构和光电子性能之间的联系。同样,HOMO - LUMO的能量和原子轨道密度也从理论上计算出来。通过分解所得单体的光谱和所涉及的HOMO和LUMO的限制,支持了咔唑电子给体单元和电子受体单元之间的电荷转移。结果表明,D-A单体CB-ODP、CB-TDP和CB-SDP可用于BHJ等有机太阳能电池的光电应用。

Implanted medical devices that have poor friction property or biofilm formation can limit their service life and cause discomfort in patients. Recently, some zwitterionic coatings have been studied to modify the biomaterials surface for lubricating function, but the grafting methods of coatings are complicated and also seldom take the bacterial antiadhesion property into account at the same time. In our studies, motivated by the properties of nature mussels and human articular, we firstly successfully synthesized double adhesion protection of self-adhesive ternary polymer coating and achieved the excellent lubrication and antifouling functionalization of the medical devices surface. In details, the X-ray photoelectron spectroscopy, scanning electron microscope and the water contact angles could characterize the successful modification on the surface of titanium substrate. Additionally, the tribological tests carried out by atomic force microscope verified the ternary polymer could enhance the lubrication property owing to the hydration lubrication mechanism. Meanwhile, it also possessed the bacterial antiadhesion property for the initial 24 h attributed to the hydration repulsive force. We believe that, as a simple and universal preparation method, the ternary polymer could make a great significance for improving the surface function of biomaterials and alleviating patients' discomfort.

植入式医疗器械摩擦性能差或形成生物膜会限制其使用寿命,并引起患者不适。近年来,人们研究了一些两性离子涂层来修饰生物材料的表面,使其具有润滑功能,但涂层的接枝方法复杂,同时也很少考虑到细菌的抗粘附性。在我们的研究中,我们以自然贻贝和人体关节的特性为动力,首次成功合成了双粘附保护的自粘三元聚合物涂层,实现了医疗器械表面优异的润滑和防污功能化。x射线光电子能谱、扫描电镜和水接触角表征了钛基表面改性的成功进行。原子力显微镜下的摩擦学试验验证了三元聚合物由于水化润滑机制而提高了润滑性能。同时,由于水合斥力的作用,在初始24 h内还具有抗细菌粘附性能。我们认为,三元聚合物作为一种简单通用的制备方法,对于改善生物材料的表面功能,减轻患者的不适具有重要意义。

Novel monomer, N, N'-bis(acryloyl) cystinamide (NBACA), was designed and synthesized with L-cystine as row material. By using this NBACA both as the monomer and crosslinker, reduction-sensitive nanohydrogel was prepared in ethanol via distillation-precipitation polymerization. The obtained nanohydrogel can provide a relatively hydrophobic environment and hydrogen-bonding sites inside the gel; therefore, it is suitable for loading hydrophobic drug. When paclitaxel that possess poor water-solubility was used as a model drug, the nanohydrogel represented a high drug-loading capacity, and dispersed well in aqueous solutions. Furthermore, the disulfide-group-containing nanohydrogel exhibited good reduction-sensitive drug-release behavior. The nanohydrogel biodegraded rapidly in a reducing environment, and released approximately 80% of the PTX within 24 h. Cytotoxicity assays showed that the PTX-loaded nanohydrogel exhibited high cytotoxicity against MCF-7 breast cancer cells, while blank nanohydrogels displayed a negligible cytotoxicity.

以 L-胱氨酸为原料,设计并合成了新型单体 N,N'-双(丙烯酰)胱氨酰胺(NBACA)。利用这种 NBACA 作为单体和交联剂,在乙醇中通过蒸馏沉淀聚合法制备了还原敏感性纳米水凝胶。得到的纳米水凝胶可以在凝胶内部提供相对疏水的环境和氢键位点,因此适合负载疏水性药物。当以水溶性较差的紫杉醇为模型药物时,纳米水凝胶具有较高的药物负载能力,在水溶液中分散良好。此外,含二硫键的纳米水凝胶还表现出良好的还原敏感性药物释放行为。细胞毒性实验表明,负载 PTX 的纳米水凝胶对 MCF-7 乳腺癌细胞具有很高的细胞毒性,而空白纳米水凝胶的细胞毒性则微乎其微。

The kinetics of ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) initiated by 1.0, 1.5 and 2.0 mol% of stannous(II) octoate/n-hexanol (Sn(Oct)2/n-HexOH) wase successfully studied by non-isothermal differential scanning calorimetry (DSC) at heating rates of 5, 10, 15 and 20 °C/min. The DSC polymerization kinetic parameters of ε-CL were calculated using differential (Friedman) and integral isoconversional methods (Kissinger-Akahira-Sunose, KAS). The average activation energy (Ea ) values obtained from Friedman and KAS methods were in the range of 64.9-70.5 kJ/mol and 64.9-80.4 kJ/mol, respectively. The values of frequency factor (A) were determined from model fitting method using Avrami-Erofeev reaction model. The average values of A for the ROP of ε-CL initiated by 1.0, 1.5 and 2.0 mol% of Sn(Oct)2/n-HexOH (1:2) were 7.3x107, 2.8x106 and 1.2x106 min-1, respectively. From kinetics studied, the polymerization rate of ε-CL increased with increasing initiator concentration. The performance of Sn(Oct)2/n-HexOH in the synthesis of poly(ε-caprolactone) (PCL) was investigated by bulk polymerization at temperatures of 140, 160 and 180 °C. Sn(Oct)2/n-HexOH (1:2) could produce high number average molecular weight ( M n = 9.0 × 104 g/mol) and %yield (89%) of PCL in a short period of time at Sn(Oct)2 concentration of 0.1 mol% and temperature of 160°C. The mechanism of the ROP of ε-CL with Sn(Oct)2/n-HexOH was proposed through the coordination-insertion mechanism.

采用非等温差示扫描量热法(DSC)研究了1.0、1.5和2.0 mol%的八酸锡/正己醇(Sn(Oct)2/正己醇)溶液在5、10、15和20℃/min加热速率下引发ε-己内酯(ε-CL)开环聚合(ROP)的动力学。采用微分法(Friedman)和积分等转换法(Kissinger-Akahira-Sunose, KAS)计算了ε-CL的DSC聚合动力学参数。Friedman法和KAS法得到的平均活化能(Ea)分别在64.9 ~ 70.5 kJ/mol和64.9 ~ 80.4 kJ/mol之间。频率因子(A)采用Avrami-Erofeev反应模型拟合。当Sn(Oct)2/n-HexOH浓度为1.0、1.5和2.0 mol%(1:2)时,ε-CL的ROP平均值分别为7.3x107、2.8x106和1.2x106 min-1。从动力学研究来看,ε-CL的聚合速率随引发剂浓度的增加而增加。采用本体聚合的方法研究了Sn(Oct)2/n-HexOH在140、160和180℃条件下合成聚ε-己内酯(PCL)的性能。Sn(Oct)2/n- hexoh(1:2)在Sn(Oct)2浓度为0.1 mol%、温度为160℃的条件下,能在短时间内生成PCL较高的数平均分子量(mn = 9.0 × 104 g/mol)和%收率(89%)。通过配位插入机理,提出了ε-CL与Sn(Oct)2/n-HexOH的ROP机理。

The research on the diffusion of water in coatings has been a hot topic in many fields, such as chemistry, coating structure and hydrogen bonding. In this paper, DGEBA epoxy coating was used as a sample to explore the diffusion process of 3 wt.% NaCl solution at different temperatures. Two-stage diffusion was established by immersion experiment and MD simulation. The synergistic effect of temperature and water on DGEBA properties was revealed by FTIR method and adsorption-desorption cyclic testing. The results showed that as the temperature increased, the saturation water content in coatings increased. At different temperatures, the diffusion process of water presented two-phase characteristics, and the influence of temperature on the diffusion process was mainly manifested in the cross-linking density at higher locations. Based on the variation law of swelling coefficient in per unit time (24 h), the conditions for water-coating interaction and formation of water clusters in this paper were proposed. The synergistic effect of water and temperature on DGEBA properties was reflected in two aspects: at lower temperature (20 °C), water would only change the physical structure of the coatings, while the water broke the DGEBA chains at higher temperature (60 °C).

水在涂料中的扩散研究已成为化学、涂料结构、氢键等诸多领域的研究热点。本文以DGEBA环氧涂料为样品,探讨了3 wt.% NaCl溶液在不同温度下的扩散过程。通过浸没实验和MD仿真建立了两级扩散。通过红外光谱法和吸附-解吸循环试验,揭示了温度和水分对DGEBA性能的协同作用。结果表明:随着温度的升高,涂层中饱和含水量增大;在不同温度下,水的扩散过程呈现两相特征,温度对扩散过程的影响主要表现在较高位置的交联密度。根据膨胀系数在单位时间内(24 h)的变化规律,提出了水-涂层相互作用和水团形成的条件。水和温度对DGEBA性能的协同作用体现在两个方面:在较低温度下(20℃),水只会改变涂层的物理结构,而在较高温度下(60℃),水会使DGEBA链断裂。

At present, bacteria continue to threaten human health, and the resistance of bacteria to antibiotics continues to increase, so the development of new antibacterial agents and antibacterial materials is increasingly important to ensure human health. In this paper, three polyether biguanide compounds with high antibacterial properties were synthesized by reacting polyetheramine T403 with o-tolylbiguanide, m-tolylbiguanide and p-tolylbiguanide (o-TTB, m-TTB and p-TTB), respectively. The antimicrobial performance of polyether biguanide against E. coli and S. aureus was evaluated using a minimum inhibitory concentration method, and the results showed that the synthesized polyether biguanide exhibited efficient and broad-spectrum antimicrobial effects. Among them, o-tolyl biguanide derivative o-TTB showed the best antimicrobial performance, with minimum inhibitory concentrations of 20 and 15 μg/mL against E. coli and S. aureus, respectively. Then, epoxy resin E51 was cured using the obtained TTB as a curing agent to prepare an epoxy resin with antibacterial properties. The inhibition of the growth of S. aureus by the cured o-TTB/E51 resin was investigated by incubating the cured epoxy resin with bacteria, and the results showed that the cured resin had a significant inhibitory effect on the growth of bacteria. The non-isothermal curing kinetics of the o-TTB/E51 system were investigated by differential scanning calorimetry (DSC) to determine the optimized curing reaction temperature, curing kinetic parameters and curing kinetics equation.

目前,细菌仍在威胁着人类的健康,而细菌对抗生素的耐药性也在不断增强,因此开发新的抗菌剂和抗菌材料对保障人类健康越来越重要。本文通过聚醚胺 T403 分别与邻甲苯双胍、间甲苯双胍和对甲苯双胍反应(邻甲苯双胍、间甲苯双胍和对甲苯双胍),合成了三种具有较高抗菌性能的聚醚双胍化合物。采用最小抑菌浓度法评估了聚醚双胍对大肠杆菌和金黄色葡萄球菌的抗菌性能,结果表明合成的聚醚双胍具有高效、广谱的抗菌作用。其中,邻甲苯基双胍衍生物 o-TTB 的抗菌性能最好,对大肠杆菌和金黄色葡萄球菌的最小抑菌浓度分别为 20 和 15 μg/mL。然后,用获得的 TTB 作为固化剂固化环氧树脂 E51,制备出具有抗菌性能的环氧树脂。通过将固化后的 o-TTB/E51 树脂与细菌培养,研究了固化后的环氧树脂对金黄色葡萄球菌生长的抑制作用,结果表明固化后的树脂对细菌的生长有明显的抑制作用。通过差示扫描量热法(DSC)研究了 o-TTB/E51 系统的非等温固化动力学,确定了优化的固化反应温度、固化动力学参数和固化动力学方程。

Among them, o-tolyl biguanide derivative o-TTB showed the best antimicrobial performance, with minimum inhibitory concentrations of 20 and 15 μg/mL against E. coli and S. aureus, respectively. Then, epoxy resin E51 was cured using the obtained TTB as a curing agent to prepare an epoxy resin with antibacterial properties. The inhibition of the growth of S. aureus by the cured o-TTB/E51 resin was investigated by incubating the cured epoxy resin with bacteria, and the results showed that the cured resin had a significant inhibitory effect on the growth of bacteria. The non-isothermal curing kinetics of the o-TTB/E51 system were investigated by differential scanning calorimetry (DSC) to determine the optimized curing reaction temperature, curing kinetic parameters and curing kinetics equation.</p>","PeriodicalId":11170,"journal":{"name":"Designed Monomers and Polymers","volume":"24 1","pages":"63-72"},"PeriodicalIF":1.6,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/ff/f1/TDMP_24_1900025.PMC7993382.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25539867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural features such as the shape, the lattice constant, the bond length, the total energy per cell, and the energy bandgap (Eg) of C13H8OS-X are studied by the calculating Partial Density Of States (PDOS), and DOS package of the Material Studio (MS) software. Calculations show that the bond length and the bond angle between atoms insignificant change as 1.316 Å to 1.514 Å for C-C, 1.211 Å for C-O, 1.077 Å to 1.105 Å for C-H; bond angle of round one changes from 118.883° to 121.107° for C-C-C, from 117.199° to 122.635° for H-C-C, from 119.554° to 123.147° for C-C-O and from 109.956° to 117.537° for C-C-H. When C13H8OS-X doped in the order of -Br, -Cu, -Kr, -Ge, -As, and -Fe then bond lengths, bond angles between atoms have a nearly constant value. Particularly for links C-X, there is a huge change in value, respectively 1.876, 1.909, 10.675, 2.025, 2.016, 2.014 Å; the total energy change from Etot = -121,794 eV to Etot = -202,859 eV, and the energy band gap decreases from Eg = 2.001 eV to Eg = 0.915 eV. The obtained results are useful and serve as a basis for future experimental research.

通过计算部分状态密度(PDOS)和材料工作室(MS)软件的 DOS 包,研究了 C13H8OS-X 的形状、晶格常数、键长、每个晶胞的总能量和能带隙(Eg)等结构特征。计算表明,原子间的键长和键角变化不大,C-C 为 1.316 Å 至 1.514 Å,C-O 为 1.211 Å,C-H 为 1.077 Å 至 1.105 Å;C-C 的第一圆键角从 118.883°变为 121.107°,H-C-C 的第一圆键角从 117.199°变为 122.635°,C-C-O 的第一圆键角从 119.554°变为 123.147°,C-C-H 的第一圆键角从 109.956°变为 117.537°。当 C13H8OS-X 按-Br、-Cu、-Kr、-Ge、-As 和-Fe 的顺序掺杂时,原子间的键长和键角的值几乎保持不变。特别是 C-X 链节,其数值变化很大,分别为 1.876、1.909、10.675、2.025、2.016、2.014 Å;总能量从 Etot =-121,794 eV 变化到 Etot =-202,859 eV,能带隙从 Eg = 2.001 eV 减小到 Eg = 0.915 eV。所获得的结果非常有用,为今后的实验研究奠定了基础。

In order to improve the flame-retardant effect and thermal behaviour of rigid polyurethane foam (RPUF), the flame retardancy of sodium alginate (SA), aluminium diethyl phosphite (ADPO2) and expandable graphite (EG) were proposed. First, the structures of RPUF with or without flame retardancy were confirmed by scanning electron microscopy (SEM). Additionally, the combustion behaviours and thermal performance of the flame-retardant polyurethane were evaluated through thermogravimetric analysis (TGA), limiting oxygen index (LOI) tests, and UL-94 tests. Finally, the cone calorimeter results reveled the RPUF/5ADPO2/7.5SA/7.5EG exhibit excellent thermodynamic properties. The results of the heat release rate (HRR), total heat release (THR), total smoke production (TSP), and smoke production rate (SPR) could demonstrate the smoke-suppressant and flame-retardant of polyurethane. The system of RPUF/ADPO2/SA/EG showed excellent flame-retardant in polyurethane.

The 1.0 G dendrimer (C22H48N10O4),3,5-di-tert-butylsalicylaldehyde and TiCl4 · 2THF were used as the synthetic materials, and the dendritic salicylaldehyde imide ligand with substituent hindrance and its titanium catalyst were synthesized by the condensation reaction of schiff base. The structure of the synthesized products was characterized by infrared spectroscopy, nuclear magnetic resonance hydrogen spectroscopy, ultraviolet spectroscopy, electrospray mass spectrometry, and inductively coupled plasma mass spectrometry, The actual structure is consistent with the theoretical design structure. Activated methylaluminoxane (MAO) was used as a catalyst precursor for ethylene polymerization in the process of ethylene catalytic. The effects of ethylene polymerization were studied in terms of the Al/Ti molar ratio, reaction time, reaction temperature, polymerization pressure, and ligand structure of the catalyst. The results show at the reaction temperature of 25°C, the reaction time was 30 min, and the ethylene pressure was 1.0 MPa and Al/Ti was 1,000, the catalytic activity can reach 78.56 kg PE/(mol Ti.h). Furthermore, high-temperature GPC-IR, DSC, and torque rheometer were used to characterized the microstructure, thermal properties, and viscoelastic state of polyethylene samples obtained. The results showed that the product was ultra-high-molecular-weight polyethylene.
