Abstract

Despite carbon nanotubes (CNTs) have garnered tremendous research interests for enhancing the electrical and thermal conductivity of polymers, it is still a considerable challenge to achieve the uniform dispersion of carbon nanotubes in polymer matrix. Herein, inspired by the mussel-inspired chemistry, we adopted the strategy of coating CNTs with polydopamine. And the polysilsesquioxane-modified CNTs (CNTs-PSQ) were obtained based on the click chemistry reaction. The FT-IR, Raman, XRD, and TGA collectively demonstrated the successful modification of PSQ on the surface of CNTs. The incorporation of PSQ could significantly improve the dispersion of CNTs in the silicon rubbers, and a strong interfacial interaction was formed between CNTs-PSQ and silicon rubber matrix, as observed from TEM images of silicon rubber/CNTs-PSQ nanocomposites. Meanwhile, compared with the nanocomposites with neat CNTs, the ones with CNTs-PSQ exhibited simultaneously improved electrical conductivity and insulating performance. This strategy proposed for the preparation of PSQ-modified CNTs provides insights toward highly insulating and thermal conducting polymers.
分布均匀的聚硅氧烷改性碳纳米管用于导热绝缘硅橡胶
尽管碳纳米管(CNTs)在提高聚合物的导电性和导热性方面获得了巨大的研究兴趣,但实现碳纳米管在聚合物基体中的均匀分散仍然是一个相当大的挑战。在此,受贻贝化学的启发,我们采用了用聚多巴胺涂覆CNT的策略。通过点击化学反应制备了聚倍半硅氧烷改性的碳纳米管(CNTs-PSQ)。FT-IR、Raman、XRD和TGA共同证明了PSQ在CNT表面的成功改性。从硅橡胶/CNTs-PSQ纳米复合材料的TEM图像中观察到,PSQ的加入可以显著改善CNTs在硅橡胶中的分散,并且CNTs-PSQ与硅橡胶基体之间形成了强烈的界面相互作用。同时,与具有纯CNTs的纳米复合材料相比,具有CNTs PSQ的纳米复合物同时表现出改善的导电性和绝缘性能。这种用于制备PSQ改性CNT的策略为高绝缘和导热聚合物提供了见解。
