聚电解质复合膜由聚(丙烯酸-共-丙烯腈)和咪唑基聚阳离子通过共混膜流延和氨溶液浸泡程序的组合制备。该膜独立且坚韧,具有优异的机械性能(拉伸强度为 6.71–23.7 MPa,断裂伸长率为 15–59%)。在氨浸泡步骤中,由于 NH3 引发的-COOH 去质子化以及与聚阳离子的原位离子交联,在膜中形成了分层结构的纳米孔。 Zeta 电位测量表明膜在中性条件下带负电。膜对盐类的截留率依次为 Na2SO4 > NaCl > MgCl2,但对甲基橙的截留率较高(>99.9%)。
Polyelectrolyte complex membranes were prepared from poly(acrylic acid-co-acrylonitrile)s and imidazolium-based polycations via a combination of blend film casting and ammonia solution immersion procedures. The membranes were free-standing and tough, showing excellent mechanical properties (with tensile strength of 6.71–23.7 MPa and elongation at break of 15–59%). Hierarchically structured nanopores were formed in the membranes during the ammonia soaking step, due to NH3-triggered –COOH deprotonation and in situ ionic crosslinking with polycations. Zeta potential measurements indicated that the membranes were negatively charged under neutral conditions. The membranes exhibited moderate rejection to salts in the order of Na2SO4 > NaCl > MgCl2, but high rejection to methyl orange (>99.9%).
