摘　　要：将具有独特叠层结构的聚乙烯醇-聚乙烯共聚物纳米纤维膜材料与环氧树脂复合,并引入紫外光吸收剂2,4-二羟基二苯甲酮,利用多相之间的强界面相互作用,制备得到了具有高柔韧性、高透明度和高紫外光过滤效果的复合透明膜.在该柔性基底上,通过压力转移法相继复合银纳米线层和还原氧化石墨烯层,形成了相互渗透的导电网络.最终得到面电阻为147Ω/Sq、可见光透过率约80%、紫外吸收率达90%的透明导电复合膜.该导电复合膜显示出良好的拉伸和弯曲性能,并在循环弯曲变形测试下保持良好的电学稳定性.A 3D hierarchically porous poly (vinyl alcohol)- co -poly (ethylene) nanofibrous membrane is compounded with an epoxy matrix and ultraviolet light absorbers (2,4-dihydroxybenzophenone).Owing to the strong interfacial interactions between the nanofibers and the epoxy,the obtained composite transparent substrate shows excellent flexibility,high transparency and high ultraviolet light-filtering effect.The AgNWs film and the reduced graphene oxide film are successively coated on the flexible substrate by a facile pressure transfer method to form the inter-penetrating conductive networks.The resulting composite transparent conductive film possesses a sheet resistance of 147 Ω/Sq,a visible light transmittance of 80%,and an ultraviolet light absorption over 90%.The film also exhibits excellent tensile and bending properties and maintains high electrical stability during cyclic bending tests.
