摘　　要：采用原位乳液聚合法制备了苯乙烯(St)-甲基丙烯酸丁酯(BMA)共聚物[P(St-co-BMA)]/氧化石墨烯(GO)复合材料,分析了P(St-co-BMA)及其复合材料的结构与性能。P(St-co-BMA)/GO复合材料的玻璃化转变温度低于P(St-co-BMA),起始热分解温度远高于P(St-co-BMA)。当m(St)/m(BMA)为30∶70时,P(St-co-BMA)/GO复合材料的拉伸强度由P(St-co-BMA)的9.5 MPa升至23.7 MPa,提高近250%,且断裂伸长率没有明显降低。Poly（styrene-co-butyl methacrylate） [P（St-co-BMA）]/graphene oxide（GO） composites were synthesized by in situ emulsion polymerization. The structure and properties of the composites were analyzed. The addition of GO could decrease the glass-transition temperature of P（St-co-BMA）. The initial thermal decomposition temperature of P（St-co-BMA）/GO composites was much higher than that of P（St-co-BMA）. The tensile strength of P（St-co-BMA）/GO composite reached 23.7 MPa, increasing by nearly 250% in comparison with 9.5 MPa of P（St-co-BMA） when the mass ratio of St to BMA was 30∶70, and the tensile elongation at break of the former did not decrease obviously.
