摘要/Abstract

摘要： 采用化学浴沉积法，以硫酸铜和硫代乙酰胺为前体、乙二胺四乙酸二钠（EDTA-2Na）为铜离子络合剂，控制Cu和S元素的摩尔比为1∶2，在80℃下反应4h，于柔性衬底聚对苯二甲酸乙二醇酯（PET）上成功制备了CuS透明导电薄膜。利用紫外可见分光光度计（UV-Vis）、X射线衍射仪（XRD）、场发射扫描电子显微镜（FESEM/EDS）、四探针测试仪以及薄膜导电性弯曲测试装置对CuS透明导电薄膜进行了表征研究。结果表明，制备的导电薄膜由均匀致密六方型的CuS纳米片组成，具有良好的导电性和透光率，且可根据不同的应用要求，通过改变反应条件方便地进行调控。CuS透明导电薄膜的最低方块电阻值仅为20Ω/□。经过250次大尺度弯曲实验，CuS透明导电薄膜依然保持理想的导电能力。

Abstract: A transparent conductive copper sulfide film was prepared on a flexible substrate PET by chemical bath deposition method at 80℃ for 4h with copper sulfate and thioacetamide as the precursors and EDTA-2Na as the copper ion complexing agent. The molar ratio of Cu and S was 1:2. The CuS conductive films were characterized by UV-Vis spectrophotometer(UV-Vis), X-ray diffraction diffractometer(XRD), field emission scanning electron microscope(FESEM/EDS), four-probe resistance analyzer and film bending test device. The results show that the as-prepared conductive films are composed of uniform and dense CuS hexagonal nanosheets, of which the conductivity and light transmittance can be easily controlled and adjusted by changing the reaction conditions according to different application requirements. The CuS transparent conductive films made under the optimized conditions, have a minimum resistance of 20Ω/□. After 250 times of large scale bending, the conductivity of the CuS transparent conductive film remains unchanged.
