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 antielectrostatic properties.

Application

PVA can be used for a variety of applications such as:
  • a nanoparticle stabilizer for the surface modification of titanium surfaces
  • in the preparation of an electrolyte for supercapacitors
  • formation of a composite with carbon nanotubes (CNTs) for thin film devices and flexible electronics
