Descrição geral
Poly(vinyl alcohol) (PVA) is a vinyl based water soluble polymer that can be used as a non-ionic surface active agent. It can also be used as a biodegradable polymer and can be incorporated in adhesives, coatings, textiles, ceramics and cosmetics. Its properties include good transparency, chemical resistance, toughness and anti-electrostatic properties.
Aplicação
PVA can be used in the preparation of hydrogel templates for drug delivery applications. It can also be used in the development of organic memory systems.
