【摘要】介绍了石墨烯的制备工艺与改性方法、石墨烯/聚合物复合材料的制备工艺。制备了氧化还原石墨烯/PVC原位聚合树脂，发现其耐热性能、热稳定时间（刚果红法）得到改善；改性的氧化还原石墨烯可明显提高PVC树脂的冲击强度和断裂伸长率，但拉伸强度略微降低，而未改性氧化还原石墨烯则会降低PVC树脂的力学性能。电镜照片显示氧化还原石烯/PVC原位聚合树脂中石量烯与案合物基体量现砖墙形纳米层层自组装结构。

Abstract: The preparation processes and modification methods of graphene were introduced as well as the preparation processes of graphene/polymer composites. Oxidation-reduction graphene/PVC resins were prepared by in-situ polymerization. Heat resistance and thermal stability time (Congo red method) of the resins were improved. Impact strength and elongation at break of the resins were improved signifi-cantly and tensile strength was reduced slightly by the addition of modified oxidation-reduction graphene. However, mechanical properties of the resins were reduced by the addition of unmodified oxidation-re-duction graphene. SEM images showed that the graphene and the polymer matrix in the modified PVC resins appeared brick-wall-like structure with self-assembled nano layers.
