AMPHOTERIC MEMBRANE AND MANUFACTURE |
摘要 |
An improved bipolar membrane, a precursor for said membrane and a process for preparing bipolar membranes and precursors are described. In the process a precursor is formed by laminating at least two polymeric layers at least one of which is non-ionic. After the formation of the precursor, the non-ionic layer or layers are chemically treated to form a stable bipolar membrane having high permselectivity and low potential drop. The novel bipolar membrane contains an interfacial layer having anionic and cationic domains. |
