采用氧化-分散-还原法制备亲有机性的石墨烯,X射线衍射分析表明获得预期产物.采用喷涂法制备了聚苯硫醚(PPS)/聚四氟蜡/石墨烯复合涂层,摩擦学性能测试结果表明复合涂层的摩擦系数低于纯PPS涂层,而抗磨寿命明显高于纯PPS涂层,石墨烯的最佳添加量为0.8 Phr(g/100 g).纯PPS涂层的磨损形式为严重的黏着磨损,而复合涂层以磨粒磨损为主,当石墨烯含量较高时出现疲劳磨损.纯PPS涂层的对偶环表面呈现厚而不连续的转移膜且存在较多垂直滑动方向的裂纹,而复合涂层的对偶环形成均匀坚韧的转移膜,转移膜的形貌与涂层的摩擦学性能相对应.
Oxidation-dispersion-reduction method was used to prepare the organophilic graphene, and X-ray diffraction analysis showed that the desired product was obtained.PPS / PTFE / graphene composite coatings were prepared by spray coating, The results of performance test show that the friction coefficient of the composite coating is lower than that of the pure PPS coating and the anti-wear life is obviously higher than that of the pure PPS coating. The best addition amount of graphene is 0.8 Phr (g / 100 g) The wear forms of the pure PPS coating are severe adhesive wear, while the composite coating is mainly abrasive wear, and fatigue wear occurs when the content of graphene is higher.For pure PPS coating, the surface of the dual rings presents thick and discontinuous transfer film Multi-axial sliding direction of the crack, and the composite coating dual rings form a uniform and tough transfer film, transfer film morphology and coating tribological properties corresponding.
