Ion selective membrane
The porous network structure provides the permeability of small molecular materials and the selective ion transmission due to the charge.
Founded in 1950 by Juda, morao, wylli, Tadao, koban, etc., the synthetic ion exchange membrane was invented. Now, many methods have been developed to manufacture ion exchange membrane, such as polymerization, impregnation, heating forming, radiation joining, etc.
