摘　　要：采用溶液共混法制备了水性聚氨酯(WPU)/氧化石墨烯(GO)复合皮革涂饰剂,研究了讨论了SDS和GO掺量对水性聚氨酯性能的影响。实验结果表明SDS的引入提高了GO在WPU中的分散均匀性,WPU/GO复合皮革涂饰剂应用试验结果表明涂层的抗水性、耐干湿擦性能显著的提高,表面光泽度好,涂层强度也有明显的提高。The waterborne polyurethane （ WPU）/grapheme oxide （ GO） complex leather finishing agents were prepared by mixing WPU and GO under ultrasonic treatment. The dispersion degree of GO nanosheets in WPU was improved by added the sodium dodecyl sulfate （ SDS）, and effects of content of SDS and GO on the performance of WPU/GO were investigated. The applied results indicated that adding SDS can improve the dispersion degree of GO nanosheets in WPU. The composite coating have excellent water resistance, wet-dry rubbing fastenss and surface gloss as well as high tensile strength.
