摘 要: 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 fiber was prepared by electro spinning. CdIn2S4 particles deposited on the surface of polymer fiber by a simple hydrothermal method. The structure of CdIn2S4/ conductive polymer fiber composites was characterized by scan electron microscopy( SEM),X-ray diffraction( XRD),ultraviolet-visible( UV-Vis),thermo-gravimetric analysis( TGA). The degradation of rhodamine B aqueous solution with the composites as the catalyst was performed under Xe lamp irradiation. The results showed that the composites had excellent photocatalytic efficiency. When photocatalytic reaction proceeded 3 h,the degradation rate of rhodamine B was 96. 2%.
