Microfiltration membrane fabrication materials

Polyethylene-co-vlnylaloohol/polyethylene-co-vinylacetate (PVA) polymers have been fabricated into membranes for both hemodialysis and microfiltration. The fabrication procedure and physical properties of the finished membrane material have not been published. Both the PMMA and PVA membranes have been developed in Japan, where most of the application studies have been performed. 

Microfiltration and ultrafiltration membranes can be made from organic polymers or inorganic materials such as ceramic, glass, or metal or organic polymers. Materials used in MF and UF membrane fabrication are shown in Table 6.1. A number of different techniques are employed to prepare synthetic MF/UF membranes the most important are phase inversion, coating, sintering, and track etching. 

The separator is an important component in a MFC, which physically separates the anode and cathode. A variety of separators have been explored for MFCs, including a salt bridge, cation exchange membrane (CEM), anion exchange membrane (AEM), bipolar membrane (BPM), microfiltration (MF) membrane, ultrafiltration (UF) membrane, and porous fabrics and porous materials.
