【摘要】 通过膜相渗透化学原位聚合法,得到了具有良好力学性能和优于基体膜微孔结构形态的 PAn/CA 复合导电膜。并系统地研究了聚合过程中掺杂酸浓度、苯胺单体与过硫酸胺摩尔比、反应时间和反应温度对膜表观形态和导电性能及 CO₂/O₂分离性能的影响,获得了制备较优性能的 PAn/CA 复合导电膜的最佳适宜条件。更多还原

【Abstract】 This paper presents the method of chemical synthesis of PAn/CA composite membrane by in-situ- permeation.The in-situ synthesis of conducting composite membranes of polyaniline（PAn）with commerical micro- porous cellulose acetate（CA）is described.In addition,the influences of different polymerization conditions on the con- ductivity and apparent selectivity（CO₂/O₂）of PAn/CA composite membrane are studied and the optimum polymeriza- tion conditions are obtained.更多还原
