摘要
采用提拉法在聚酰亚胺薄膜表面分步涂覆了银纳米线及疏水纳米二氧化硅,分别构筑了导电网络及超疏水涂层,制备了超疏水抗静电透明薄膜.研究结果表明,超疏水抗静电透明薄膜保持了较高的透光性,其透光率高于90%.同时,银纳米线网络的构筑有效增加了超疏水抗静电透明薄膜的导电性,使其表面电阻介于10^(6)~10^(10)Ω之间,达到了抗静电要求.水滴在该薄膜表面静态接触角高达156.4°,滚动角小于1°,展现了优异的超疏水特性.通过导电网络及疏水涂层的构筑,实现了透明及抗静电超疏水多功能的统一.
Silver nanowires and hydrophobic nano-silica were coated on the surface of polyimide film by a simple pulling method.During the process,the conductive network and superhydrophobic coating were constructed respec⁃tively.The results show that the static contact angle of water droplets on the surface of the film is as high as 156.4°,and the rolling angle is less than 1°,indicating that the film has excellent superhydrophobic characteristics.At the same time,the film maintains high light transmittance,and its light transmittance is higher than 90%.The construc⁃tion of silver nanowire network effectively increases the conductivity of the film,making the surface resistance of the film between 10^(6)-10^(10)Ω,meeting the anti-static requirements.In short,through the construction of conductive network and hydrophobic coating,the unity of transparent,antistatic and superhydrophobic functions is realized.
