采用多元醇法制备了直径约 40 nm、长径比约 300 的银纳米线. 以聚对苯二甲酸 乙二醇酯-1,4-环己烷二甲醇酯 (polyethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate, PETG) 膜为基底, 采用旋涂法制备了银纳米线柔性透明导电薄膜, 探究了不同 辅助成膜剂对成膜性能的影响. 发现以黄原胶为辅助成膜剂制备的银纳米线薄膜具有较理想 的透明性和导电性; 银纳米线分散液沉积密度对银纳米线薄膜的透明性和导电性有重要影响, 当沉积密度为 10 mg/cm2 时, 银纳米线薄膜的透光率和导电性能最优; 弯曲测试结果表明, 银 纳米线薄膜具有很好的柔韧性.

Silver nanowires with a diameter of approximately 40 nm and a length to diameter ratio of approximately 300 were prepared via the polyol method. Subsequently, uniform, stable, and flexible transparent conductive films of silver nanowires were prepared by the spin coating method. Polyethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate (PETG) film was used as the substrate and Chitosan or Xanthan gum as the auxiliary film forming agent. It was found that the deposition density of silver nanowires dispersion had an significant effect on the transparency and electrical conductivity of silver nanowires flexible transparent conductive films. The light transmittance and electrical conductivity of the films reached a maximum when the deposition density was 10 mg/cm2 . The bending performance test of the film indicated good flexibility.
