说明

一般描述

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.
 

应用

PVA 用作生物试剂，以测试氧化锌纳米颗粒的分散。[1]PVA 已被评估为有效的抗蛋白质材料。2 它可用于稳定直径 3-8nm 的金胶体。[2]
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.
