利用高压静电纺丝技术,制得含有羧基的导电聚合物纤维(聚偏氟乙烯/苯乙烯-马来酸酐共聚物/纳米石墨),高温水热条件下在纤维表面制备CdIn2S4颗粒,得到CdIn2S4/导电聚合物纤维复合材料。运用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、紫外-可见吸收光谱仪(UV-Vis)和热失重分析仪(TGA)对复合材料的结构进行表征。并利用350 W氙灯模拟太阳光进行光催化降解罗丹明B。结果发现,CdIn2S4/导电聚合物纤维复合材料的降解效率高于CdIn2S4粉体和Degussa P25 TiO2粉体,光催化降解3 h,罗丹明B的降解率为96.2%。
Conductive polymer fibers containing carboxyl groups (polyvinylidene fluoride / styrene-maleic anhydride copolymer / nanographite) were prepared by high-pressure electrospinning technology. CdIn2S4 particles were prepared on the surface of the fibers under high temperature and hydrothermal conditions to obtain CdIn2S4 / Conductive Polymer Fiber Composites. The structure of the composites was characterized by SEM, XRD, UV-Vis and TGA. The photocatalytic degradation of rhodamine B by using 350 W xenon lamp simulated sunlight was carried out. The results showed that the degradation efficiency of CdIn2S4 / conductive polymer fiber composite was higher than that of CdIn2S4 powder and Degussa P25 TiO2 powder, and the degradation rate of Rhodamine B was 96.2% after 3 h photocatalytic degradation.
