Objective: The objective of this study is to conduct a comparative investigation into the performance of multiwall carbon nanotube (MWCNT) and carbon wastes (C-waste) derived from the aluminum industry in the creation of thermally stable cementitious mortar. Specifically, the research aims to assess their impact on compressive strength and thermal stability, with a focus on identifying the superior additive for enhancing the properties of cement mortar. Methods: Cement mortar is produced using a blend of CEMIII cement and sand passing through a 1 mm sieve. Various ratios of MWCNT and C-waste, ranging from 0.1% to 0.7%, are incorporated into the mixture. Compressive strength tests are conducted at different intervals, up to 90 days, to evaluate the effects of additives on strength enhancement. Additionally, the resistance to high temperatures is examined by subjecting the mortar samples to firing temperatures up to 700 degrees Celsius. Results: The inclusion of both MWCNT and C-waste leads to improvements in compressive strength values, with the most significant enhancement observed at 0.1% concentration, resulting in approximately 70MPa and 75MPa at 90 days, respectively. Notably, C-waste demonstrates superior physical and mechanical properties compared to MWCNT, along with a lower production cost. Moreover, both additives exceed the specified limits for thermal resistance in mortar, achieving measurements of about 60MPa for MWCNT and 63MPa for C-waste when exposed to firing temperatures of 700 degrees Celsius. These results highlight the higher thermal stability of C-waste relative to MWCNT. Conclusion: In conclusion, this study confirms the efficacy of utilizing C-waste as an additive in cementitious mortar production, showcasing its superior performance over MWCNT in terms of compressive strength enhancement and thermal stability. The findings underscore the potential of repurposing industrial by-products such as C-waste to improve material properties while also addressing environmental concerns and reducing production costs in construction applications.
研究目的本研究的目的是对多壁碳纳米管(MWCNT)和铝工业产生的碳废物(C-waste)在创建热稳定性水泥砂浆中的性能进行比较调查。具体而言,研究旨在评估它们对抗压强度和热稳定性的影响,重点是找出可提高水泥砂浆性能的优质添加剂。方法:使用 CEMIII 水泥和过 1 毫米筛子的沙子混合制成水泥砂浆。在混合物中掺入不同比例的 MWCNT 和 C 废料,比例从 0.1% 到 0.7% 不等。在最长 90 天的不同时间间隔内进行抗压强度测试,以评估添加剂对强度增强的影响。此外,通过将砂浆样品置于高达 700 摄氏度的焙烧温度下,还对其耐高温性能进行了检测。结果显示添加 MWCNT 和 C 废料可提高抗压强度值,其中浓度为 0.1%时抗压强度的提高最为显著,90 天时的抗压强度值分别约为 70MPa 和 75MPa。值得注意的是,与 MWCNT 相比,C-废弃物具有更优越的物理和机械性能,同时生产成本也更低。此外,这两种添加剂都超过了砂浆中热阻的规定限制,当暴露在 700 摄氏度的焙烧温度下时,MWCNT 的测量值约为 60 兆帕,C-废弃物的测量值约为 63 兆帕。这些结果突出表明,相对于 MWCNT,C-废弃物具有更高的热稳定性。结论总之,本研究证实了利用 C 废料作为水泥基砂浆生产添加剂的功效,并展示了其在抗压强度增强和热稳定性方面优于 MWCNT 的性能。研究结果强调了将 C 废料等工业副产品重新用于改善材料性能的潜力,同时还解决了建筑应用中的环境问题并降低了生产成本。

Objective: In the current research, the creep behavior of polyethylene (PE) matrix nanocomposites reinforced with different content of clay nano particles (i.e., 0, 1, 3, 5, 10wt%) at different temperatures (25 and 50℃) has been investigated. Methods: In order to produce composite samples of pure PE reinforced with different percentages of clay (0, 1, 3, 5 and 10% by weight), a twin extruder was used in the temperature range of 200-230℃. Also, to produce the standard samples, an injection machine was used using in the temperature range of 220-230℃. The samples were subjected to a constant load, typically around 0.7 to 0.8 times the yield strength, at 25 and 50℃ , and at constant strain rate of 0.1min-1. Results: The creep investigations showed that for PE and its nanocomposites the creep trend could be divided into primary, secondary, and tertiary stages. The length of each stage depended strongly on both temperature and the stress level at which the samples tested as well as the clay content. It was observed that adding nano particles in small amounts (1wt%) led to an increase in the length of the creep life of PE and it also improved this property in both temperatures. Conclusion: It was observed that increasing test temperature from causes to decrease the creep strength as well as a rapid onset of plastic deformation for all materials including PE and its nanocomposites. PE nanocomposites with higher than 1wt% clay exhibited a noticeable drop in creep strength particularly at 50℃.
研究目的在当前的研究中,研究了不同含量的粘土纳米颗粒(即 0、1、3、5、10wt%)增强的聚乙烯(PE)基纳米复合材料在不同温度(25 和 50℃)下的蠕变行为。研究方法为了生产纯聚乙烯与不同比例粘土(0、1、3、5 和 10%(重量百分比))增强的复合材料样品,使用了双挤压机,温度范围为 200-230℃。此外,为了生产标准样品,还使用了注塑机,温度范围为 220-230℃。样品在 25 和 50℃的温度下,以 0.1 分钟-1 的恒定应变速率承受恒定载荷,通常约为屈服强度的 0.7 至 0.8 倍。结果:蠕变研究表明,聚乙烯及其纳米复合材料的蠕变趋势可分为初级、中级和高级阶段。每个阶段的长短在很大程度上取决于测试样品的温度和应力水平以及粘土含量。据观察,添加少量(1wt%)纳米颗粒可延长聚乙烯的蠕变寿命,而且在两种温度下都能改善这一特性。结论据观察,试验温度升高会导致蠕变强度降低,并使所有材料(包括聚乙烯及其纳米复合材料)的塑性变形迅速开始。粘土含量高于 1wt% 的聚乙烯纳米复合材料的蠕变强度明显下降,尤其是在 50℃时。

Background: The presence of natural fiber in composites has shown a positive influence on the resilience of the reinforced polymer composites but this influence shows variability with Natural fiber Surface treatment, concentration of treatment solution and the length of treatment time. 5wt.% of sodium hydroxide (NaOH) alkali solution concentration has shown to be effective and efficient in dissolving the hemicellulose and the lignin portions while preserving the cellulose part of the fiber. There is enough literature on the chemical, physical, mechanical and thermal properties of Natural fibers but there is no comprehensive study on the chemical composition, morphology and concentration of the chemical compositions, water absorption behavior and thermal properties of Raffia hookeri fibers. Objective: Given that these properties vary with both the plant type and Botanical species, we are taking this advantage to study in detailed the morphological and composition of Raffia hookeri fiber and to Characterize the fiber for the evaluation of Mechanical Properties for Technological application. Methods: Raffia hookeri fiber was extracted and the basic technological application properties such as moisture and water adsorption, morphology, chemical, physical and thermal properties were analyzed using, chemical composition analysis, scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), Fourier transformed Infrared (FTIR), X-ray diffraction (XRD) and Thermo gravimetric analysis (TGA) while tensile test was used to evaluate the mechanical behavior of the fibers. Results: Chemical analysis revealed that the fiber was made up of cellulose (40wt.%), hemicellulose (20wt.%), lignin (33wt.%) and extractives 7wt.%, Thermal analysis indicated thermal stability up to 220oC, while the SEM/EDS results revealed that the effect of treatment on the fiber surface increased with the treatment time and reached maximum after 10h. This variability inferred on the morphological composition which recorded modifying effects both on the fiber-polymer matrix and the mechanical properties of the treated fibers. The FT-IR and XRD results indicated modification of the functional groups on the fiber morphology which improved on the mechanical, moisture and water adsorption capacity of the treated fibers. Conclusion: The alkali treatment has modifying effects on Raffia hookeri fiber morphology and chemical composition which affect its technological application Properties.
背景:复合材料中天然纤维的存在对增强聚合物复合材料的回弹性有积极的影响,但这种影响随天然纤维的表面处理、处理溶液的浓度和处理时间的长短而变化。5 wt。结果表明,百分之五的氢氧化钠(NaOH)碱溶液浓度可以有效地溶解半纤维素和木质素部分,同时保留纤维的纤维素部分。关于天然纤维的化学、物理、力学和热性能方面的研究文献较多,但对拉菲草纤维的化学组成、化学成分的形态和浓度、吸水行为和热性能等方面的研究还不够全面。目的:考虑到不同植物类型和植物种类的不同,我们利用这一优势,详细研究了拉菲叶纤维的形态和组成,并对拉菲叶纤维进行了表征,以评价其力学性能,为技术应用提供依据。方法:采用化学成分分析、扫描电镜(SEM)、能谱分析(EDS)、傅里叶变换红外(FTIR)、x射线衍射(XRD)和热重分析(TGA)等技术手段,分析了拉菲亚hookeri纤维的吸湿和吸水性能、形貌、化学、物理和热性能等基本工艺应用性能,并用拉伸试验评价了纤维的力学性能。结果:化学分析表明,该纤维由纤维素(40wt.%)、半纤维素(20wt.%)、木质素(33wt.%)和提取物(7wt. %)组成。热分析表明,纤维表面的热稳定性可达220℃,而SEM/EDS结果表明,随着处理时间的延长,处理对纤维表面的影响逐渐增强,在10h后达到最大。这种可变性是从形态组成上推断出来的,它记录了对纤维-聚合物基体和处理过的纤维的机械性能的改性作用。FT-IR和XRD结果表明,官能团对纤维形貌的改变,提高了纤维的力学性能、吸湿性能和吸水性能。结论:碱处理对拉菲的纤维形态和化学成分有改性作用,影响拉菲的工艺应用性能。

Objective: This paper investigates a range of optimization approaches for advanced composite structural items made of polymers with inclusion of specially formulated glass fibers (GFs) (either continuous linear strands or mesh matrix). Methods: Ridged polymer test panels were tested for flexural strength using variable loads (ASTM D790 standard). Tested variables included: (a) thickness and amount of GF dispersed within polymer matrix, (b) addition and placement of open mesh woven element on open flat surfaces of polymer panel, and (c) addition and selective placement of tension setters on ridges. Results: Optimal amounts of additives, design and compositions were determined for strength and impact resistance of polymer composites. Tension setters were found to be best embedded in laterally extending rib elements of composite structure, preferably as end-portions of rib elements. Open mesh woven element should be placed strategically within polymeric body to provide impact strength where needed the most. Conclusion: These optimized composite structural designs showed higher strength (up to 331% of the base polymer), higher impact resistance (up to 551% of the base), with additional benefit of reduced weight by 15-21%, as compared to conventional polymer panels.

Objective: Glass fiber reinforced composites with epoxy were prepared using thermally reduced graphene oxide (TRGO) and multiwall carbon nanotubes (CNTs) as electrically conductive nano filler. Electrical, mechanical, dielectric and electromagnetic interference (EMI) shielding properties were analyzed and compared. Methods: TRGO was prepared by modified hummers method and X-ray diffraction spectra showed the carbon hexagonal structure with 6-8nm of thickness. Tensile, flexural and impact strength of these composites was comparable and increase with increasing filler content. The effect of TRGO and CNTs on AC & DC conductivity of composites was also compared, which showed that increasing the TRGO content increased the electrical conductivity little better than that of CNTs filled composite. Results: The dielectric properties also improved better for composite incorporating TRGO than with the CNTs, at higher frequency (5MHz). With addition of 2.0% TRGO and CNTs, the maximum SET observed was 32dB at lower frequency, with TRGO-based composite manage to maintain its performance even at higher frequency whereas, this value dropped to 24dB for CNT-based composite at 5MHz of frequency. Conclusion: The dispersion state, the composition of the fillers, and their interaction with matrix are the most important factors in these polymeric composites for the development in EMI shielding effectiveness.
目的:采用热还原氧化石墨烯(TRGO)和多壁碳纳米管(CNTs)作为导电纳米填料制备环氧玻璃纤维增强复合材料。对其电气、机械、介电和电磁干扰屏蔽性能进行了分析和比较。方法:采用改进hummers法制备TRGO, x射线衍射光谱显示其厚度为6 ~ 8nm的碳六方结构。这些复合材料的拉伸、弯曲和冲击强度相当,并且随着填料含量的增加而增加。比较了TRGO和CNTs对复合材料交直流电导率的影响,结果表明,增加TRGO含量对复合材料电导率的提高效果略好于填充CNTs的复合材料。结果:在更高频率(5MHz)下,添加TRGO的复合材料的介电性能也比添加CNTs的复合材料得到了更好的改善。当添加2.0% TRGO和CNTs时,在较低频率下观察到的最大SET为32dB, TRGO基复合材料即使在较高频率下也能保持其性能,而在5MHz频率下,CNTs基复合材料的SET值降至24dB。结论:聚合物复合材料的分散状态、填料的组成及其与基体的相互作用是影响电磁干扰屏蔽性能的重要因素。

Conclusion: The dispersion state, the composition of the fillers, and their interaction with matrix are the most important factors in these polymeric composites for the development in EMI shielding effectiveness.","PeriodicalId":385339,"journal":{"name":"Journal of Modern Polymer Chemistry and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115796989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
