Poly (Vinyl Alcohol) PVA -Based Polymer Membranes

In recent years, many researchers have devoted considerable attention to the development of membrane science and technology. Different important types of membranes, such as those for: nanofiltration, ultrafiltration, microfiltration, separation of gases and inorganic membranes, facilitated or liquid membranes, catalytic and conducting membranes, and their applications and processes, such as wastewater purification and bio-processing have been developed. In fact, almost 40 percent of the sales from membrane production market are for purifying wastewaters. Hydrogel membranes fulfil many of the important conditions for most of above-mentioned application fields. Therefore, the authors have focused this book on the applications of PVA-based membranes in areas such as for separation membranar processes, fuel cells, sensors, biochemical/medical applications, catalyst or PVA derivatives membranes as gas and vapour barriers.
