General description
Polyvinyl alcohol(PVA) is a linear hydrophilicsynthetic polymer with a monoclinic crystal structure. It can be synthesized via the polymerization of vinyl esters orethers, with subsequent saponification or transesterification. Due to itsexcellent physical and chemical properties, PVA has been widely used inadhesives, fibers, paper industry, drug delivery, and tissue engineering.
Application
PVA is used as a biological reagent to test the dispersion of zinc oxide nanoparticles. PVA has been evaluated as an effective protein resistant material.2 It may be used to stabilize gold colloids of diameter 3-8nm.
Poly(vinyl alcohol) can be used as a secondary template in the synthesis of mesoporous zeolites.
It can be used to prepare a hydrogel template to produce homogeneous microparticles for sustained drug release. PVA is used as a stabilizer in micro-particle preparation due to its high tensile strength and flexibility.

In this work, a new macroporous molecularly imprinted cryogel (MIP composite cryogel) was synthesized by glutaraldehyde cross-linking reaction of poly(vinyl alcohol) (PVA) particles and amino-modified molecularly imprinted core-shell nanoparticles. The MIP core-shell nanoparticles were prepared using propranolol as a template
