采用高温碳化法制备活性炭纤维织物(carbon network,CNW)。以CNW为基底采用电沉积法制备CNW/Cu_2O复合材料。利用X射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM)、电子单纱强力仪、紫外-可见光分光光度计(UV-vis)等分别对样品进行物相结构表征、微观结构表征、机械性能及脱色性能测试。结果表明:所得Cu_2O薄膜产物纯净、晶粒大小均匀、尺寸为200～400 nm;CNW/Cu_2O复合材料表现出良好的机械拉伸性能;CNW/Cu_2O复合材料初次对甲基橙溶液的脱色率高达96.2%,重复使用10次,脱色率衰减14.3%。 High temperature carbonization was used to prepare carbon network (CNW). Preparation of CNW / Cu_2O Composites by Electrodeposition Using CNW as Substrate. The structures of the samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), electron single yarn strength tester and UV-vis spectrophotometer , Mechanical properties and bleaching performance test. The results show that the obtained Cu 2 O thin film has a pure product and a uniform grain size of 200-400 nm. The CNW / Cu 2 O composite exhibits good mechanical tensile properties. The decoloration rate of CNW / Cu 2 O composites for methyl orange solution is up to 96.2%, repeated use of 10 times, decolorization rate of 14.3% decline.
