摘要 通过自由基聚合法制备无规共聚物聚甲基丙烯酸缩水甘油酯/N-乙烯基咔唑P(GMA-co-NVC),并将其对多壁碳纳米管(MWCNTs)进行非共价键表面修饰得到P(GMA-co-NVC)/MWCNTs,再与环氧树脂(EP)复合,采用浇注成型法制备聚合物改性碳纳米管/环氧树脂复合材料。通过拉伸实验、电阻率测试和差式扫描量热法研究聚合物改性碳纳米管对环氧树脂力学、电学和热学性能的影响。结果表明:修饰后的碳纳米管比原始碳纳米管对环氧树脂有更明显的增强和增韧作用,当P(GMA-co-NVC)/MWCNTs质量分数为0.25%时,复合材料的体积电阻率为106Ω·m,相比于纯环氧树脂(1014Ω·m)下降了8个数量级,玻璃化转变温度(Tg)也由144℃提高至149℃。

Abstract:An amphiphilic random copolymer of polyglycidyl methacrylate-co-N-vinyl carbazole P(GMA-co-NVC) was synthesized by free radical polymerization and was used to noncovalently modify multi-walled carbon nanotubes (MWCNTs). The obtained P(GMA-co-NVC)/MWCNTs was mixed with epoxy resin and used to reinforce epoxy resin. Polymer modified carbon nanotubes/epoxy resin composites were prepared by a casting molding method. Tensile test, electrical resistivity test and differential scanning calorimeter(DSC) analysis were used to study the effect of polymer modified carbon nanotubes on the mechanical, electrical, and thermal properties of epoxy resin. The results show that the epoxy composite reinforced with P(GMA-co-NVC)/MWCNTs shows a remarkable enhancement in both tensile strength and elongation at break compared to either the pure epoxy or the pristine MWCNTs/epoxy composites. In addition, the electrical conductivity of epoxy is significantly improved and the volume resistivity decreases from 1014Ω·m to 106Ω·m with 0.25% mass fraction loading of P(GMA-co-NVC)/MWCNTs. Moreover, glass transition temperature of the epoxy composite also increases from 144℃ to 149℃.
