摘　　要：通过喷涂工艺在铝基片表面制备出聚四氟乙烯(PTFE)-聚苯硫醚(PPS)复合超疏水涂层,该复合涂层具有与荷叶表面类似的二次结构,与水的静态接触角为155o,滚动角为7o.与纯PTFE超疏水涂层相比,PTFE涂层中引入PPS后,涂层的粘附力从5级提高到1级,铅笔硬度从4B提高到4H,柔韧性从(10±0.1)mm提高到(1±0.1)mm,可以更好地满足工业应用要求.The superhydrophobic polytetrafluoroethylene-polyphenylene sulfide （PTFE-PPS） composite coating was prepared by spraying coating on the aluminum substrate. Scanning electron microscopy （SEM） investigation indicated that the composite coating had the similar surface structure to that of lotus leaf. The water contact angle on the coating surface was 155° and the sliding angle was 7°. Compared with the pure superhydrophobic PTFE coating on the aluminum substrate, the conglutination force of the composite coating was improved from grade 5 to grade 1, the pencil rigidity was increased from 4B to 4H, and the flexility of the composite coating was improved from （10±0.1） mm to （ 1 ±0.1） mm. The composite coating was sufficient to the requirements of industrial application.
