以膨胀石墨(EG)负载对苯二酚后和4,4'-二氟二苯甲酮单体,采用原位亲核缩聚法制备了聚醚醚酮/膨胀石墨复合材料(PEEK/EG).通过黏度分析法探讨了膨胀石墨对PEEK相对分子质量的影响;采用X射线衍射、差示扫描量热分析和热重分析研究了膨胀石墨对PEEK结晶性能和热性能的影响;通过扫描电镜表征了膨胀石墨在PEEK基体中的分散形态;通过摩擦测试仪研究了PEEK及PEEK/EG摩擦性能.结果表明,原位缩聚过程中引入EG不会影响PEEK晶型;EG含量为0.5％时PEEK/EG复合材料初始分解温度提高10℃,同时,EG在基体中分散效果良好.PEEK/EG-0.5％的磨损率为4.00×10-6 mm2/(N·m),远低于纯PEEK的15.80×10-6 mm2/(N·m).
