A membrane comprising: a) a first layer comprising a first polymer or a fourth polymer having ionic groups having a polarity opposite to that of ionic groups of a third polymer; b) a second layer comprising a second polymer having ionic groups of the same polarity as the ionic groups of the third polymer; and c) a third layer comprising a co-continuous polymer network of: (i) a third polymer having ionic groups and a pore network; and (ii) a fourth polymer having an ionic group having a polarity opposite to that of the ionic group of the third polymer; wherein layer c) is interposed between layer a) and layer b), and the third polymer is obtainable by a process comprising phase separation of the third polymer from a curable composition for making the third polymer. 一种膜，其包括：a)第一层，其包含第一聚合物或第四聚合物，所述第一聚合物或第四聚合物具有极性与第三聚合物的离子基团的极性相反的离子基团；b)第二层，其包含第二聚合物，所述第二聚合物具有极性与第三聚合物的离子基团的极性相同的离子基团；以及c)第三层，其包含以下聚合物的共连续聚合物网络：(i)具有离子基团和孔网络的第三聚合物；和(ii)第四聚合物，所述第四聚合物具有极性与所述第三聚合物的离子基团的极性相反的离子基团；其中层c)介于层a)和层b)之间，并且所述第三聚合物可通过包括将所述第三聚合物与
