| 摘 要： | 采用熔融挤出法将热致性液晶聚合物(TLCP)与酚醛树脂(PF)熔融挤出，分别加入改良Hummers法制备的氧化石墨烯(GO)、硅烷偶联剂改性GO(KH550 GO、KH560 GO)，制备了TLCP/PF/GO混杂复合材料,研究了加入GO对TLCP/PF/GO混杂复合材料的力学性能、摩擦磨损性能的影响。结果表明，硅烷偶联剂处理的GO能一定程度提高复合材料的摩擦磨损性能和力学性能，特别是TLCP/PF/KH560 GO混杂复合材料的摩擦因数稳定，在150 ℃和250 ℃下的体积磨损率分别降低了20.6 %和23.1 %，材料的冲击强度提高了18.6 %。

| Abstract: | Composites of a thermotropic liquid crystal polymer (TLCP), phenol formaldehyde (PF), and silane coupling agent KH550 or KH560 treated graphene oxide were prepared via melting extrusion. The mechanical properties and friction and wear properties of the composites were studied. The abrasion surface of the composites was observed using scanning electron microscope. When graphene oxide was treated with KH560, the volume wear rate of the composites decreased by 20.6 % and 23.1 % at 150 ℃ and 250 ℃, respectively, the impact strength was increased by 18.6 %. |
