摘　　要：采用静电纺丝技术制备了五种聚乙烯亚胺(PEI)含量的醋酸纤维素/聚乙烯吡咯烷酮复合纤维膜。利用扫描电镜、红外光谱等手段对膜材料进行了表征,比较了PEI掺杂量对复合纤维膜形貌的影响。将这些复合纤维膜组装到玻碳电极表面,利用循环伏安电化学研究了这些膜电极的在弱酸/强酸下的电催化放氢性能。结果表明,PEI功能化的复合纤维膜电极的电催化放氢性能显著增强。Five fibrous membranes contained different amounts of polyethyleneimine(PEI)were prepared with electrospinning a composite of cellulose acetate and polyvinylpyrrolidone.All fibrous membranes were characterized by SEM and FTIR.The influence of doping amount of PEI on the morphology of fibrous membranes was discussed.The composite fibrous membranes were then assembled on the surface of glassy carbon electrode.Electrocatalytic hydrogen evolution performance of these membrane electrodes was investigated by cyclic voltammetry under weak or strong acid surrounding.The results demonstrated that the electrocatalytic performance of PEI-functionalized membrane electrode was significantly enhanced.
