一种氧化石墨烯-银纳米线可拉伸透明导电薄膜

A Stretchable Transparent Conductive Film Based on Graphene Oxide/Silver Nanowire

柔性电子器件主要应用于折叠手机、医疗健康监测、人工智能和太阳能电池等方面,是当前研究的热点。针对银纳米线(AgNW)与衬底之间存在的粘附性较弱、易剥落、在空气中易氧化而使阻值变大等问题,文章设计了一种以PDMS为柔性衬底的三层透明导电薄膜,探究了曝光次数和氧化石墨烯不同涂覆方式对薄膜光电特性的影响。结果表明,该导电薄膜达到了12Ω/□的方块电阻,透过率超过80%。在48%的拉伸情况下仍然保持着较好的导电性。

Silver nanowire(AgNW)-based transparent conductive films are mainly applied in the fields of foldable mobile,health monitoring,artificial intelligence,and solar cell,which are the hot spots at present.However,silver nanowires are easy to get oxided in the air,and weakly bonded to the substrate,making the resistance larger.In this paper,a three-layer composite transparent conductive films on PDMS substrates was demonstrated.The influences of exposure times and different coating methods of graphene oxide on both the optical and electrical properties had been explored.Ultimately,a sheet resistance of 12Ω/□with above 80%transmittance had been attained.Meanwhile,the film retained its functionality under 48%stretching.
