Nylon 610/nylon 610-grafted graphene oxide (nylon 610/GO-g-nylon 610) composites were fabricated using acyl chloride-functionalized graphene oxide by in-situ interfacial polymerization. GO-g-nylon 610 was synthesized by the condensation reaction between the acyl chloride groups of GO and the amino groups at the nylon 610 chains during the in-situ polymerization. Nylon 610/GO composites without grafting nylon 610 onto GO were also prepared to investigate the influence of grafting nylon 610 on the interfacial adhesion between GO and the nylon 610 matrix. The thermal properties of the nylon 610/GO-g-nylon 610 composites were enhanced with increasing GO-g-nylon 610 content in the nylon 610 matrix. The degradation temperature and thermal conductivity of the nylon 610/GO-g-nylon 610-10 composite were increased to 72.2 °C and 36.9%, respectively, compared with those of pure nylon 610. The crystallinity of the nylon 610/GO-g-nylon 610-10 composite was significantly lower than that of pure nylon 610 due to the hindered mobility of the nylon 610 chains by the strong interfacial adhesion between the GO-g-nylon 610 and the nylon 610 matrix.
采用酰氯功能化氧化石墨烯通过原位界面聚合制备了尼龙610/尼龙610接枝氧化石墨烯（尼龙610/GO-g-尼龙610）复合材料。在原位聚合过程中，通过GO的酰氯基团与尼龙610链上的氨基之间的缩合反应合成了GO-g-尼龙610。还制备了未将尼龙610接枝到GO上的尼龙610/GO复合材料，以研究接枝尼龙610对GO与尼龙610基体之间界面粘附力的影响。随着尼龙610基体中GO-g-尼龙610含量的增加，尼龙610/GO-g-尼龙610复合材料的热性能得到增强。与纯尼龙610相比，尼龙610/GO-g-尼龙610-10复合材料的降解温度和热导率分别提高到72.2℃和36.9%。由于GO-g-尼龙610与尼龙610基体之间的强界面粘附力阻碍了尼龙610链的迁移率，尼龙610/GO-g-尼龙610-10复合材料的结晶度明显低于纯尼龙610。
