General description

Poly(vinyl alcohol) 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 as a chelating agent in the synthesis of zirconium oxide nanopowder from zirconium hydroxide. It can also be used as biopolymer which finds potential application in fiber based food packaging.

Skin injuries are frequently encountered in daily life, but deep wounds often poorly self-heal and do not recover completely. In this study, we propose a novel skin patch that combines antibiotic, cell-derived extracellular matrix (ECM) and biocompatible polyvinyl alcohol (PVA)
