Keyword:  纳米钯PVA/PEI超细纤维膜水相稳定性静电纺丝;
Abstract: 通过静电纺丝技术制得了聚乙烯醇(PVA)/聚乙烯亚胺(PEI)超细纤维膜,使用戊二醛蒸汽交联使其具有水稳定性,进而将交联后的PEI/PVA超细纤维膜浸入PdCl2溶液中至吸附平衡,以硼氢化钠(NaBH4)为还原剂,于超细纤维膜表面原位合成Pd纳米粒子.用场发射扫描电子显微镜(FE-SEM)、傅里叶变换红外(FTIR)、紫外可见分光光度计(UV)等技术表征了PVA/PEI超细纤维,交联后的PEI/PVA超细纤维膜及负载有Pd纳米粒子的PEI/PVA超细纤维膜.研究表明:交联后的PVA/PEI超细纤维膜具有良好的水相稳定性,Pd纳米粒子在PVA/PEI超细纤维膜表面均匀分布,负载有Pd纳米粒子的PEI/PVA超细纤维膜对Cr(Ⅵ)的还原反应具有良好的催化性能.
