摘要

众所周知，碳纳米管（CNT）的加入会强烈影响它们分散到其中的聚合物的热机械和电学性能。功能化碳纳米管和聚合物复合材料的常见溶剂混合分散方法可以改善热、机械和电学性能。在本研究中，使用常见的溶剂分散混合方法，使用功能化单壁碳纳米管（COOH-SWCNTs）和聚甲基丙烯酸甲酯来制备聚合物纳米复合材料。COOH单壁碳纳米管在复合材料中的均匀分散导致这些复合材料的热机械性能的改善；使用扫描电子显微镜对此进行分析。

Thermomechanical properties of PMMA and modified SWCNT composites

It is well known that the addition of carbon nanotubes (CNTs) can strongly affect the thermomechanical and electrical properties of the polymer into which they are dispersed. The common solvent mixing dispersion method of functionalized CNTs and polymer composites can improve thermal, mechanical, and electrical properties. In this study, functionalized single-walled CNTs (COOH-SWCNTs) and poly(methyl methacrylate) were used to fabricate the polymer nanocomposites using a common solvent dispersion mixing method. The homogenous dispersion of COOH-SWCNTs in the composites resulted in improved thermomechanical properties of these composites; this was analyzed using scanning electron microscopy.
