General description

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.

Application

PVA can be used for a variety of applications such as:
  • a stabilizer in the synthesis of nanoparticles
  • preparation of biodegradable polymeric nanoparticles for biomedical applications
  • immobilization of glucose oxidase for the development of a biosensor
