产品介绍
聚乙烯醇（PVOH）是一种形成乙烯醇和乙酸乙烯酯共聚物的亲水性线性聚合物。因此，聚乙烯醇聚合物的结构性质取决于聚合和水解的程度。这些变化会引起化学和物理性的改性，如聚合物中的酯化、醚化、结晶以及离子-聚合物的络合。改性的PVOH结构可用于生物医学应用中。
应用
NaA沸石颗粒已被分散在聚（乙烯醇）基质中以制备混合基质膜用于对水-丁醇混合物的蒸发分离研究。基于聚（乙烯醇）/明胶的生物相容性聚合物支架已用于3D癌症模型的设计。
General Description
Polyvinyl alcohol (PVOH) is a hydrophilic linear polymer which forms copolymers of vinyl alcohol and vinyl acetate. Hence, the structural properties of polyvinyl alcohol polymers depend on the extent of polymerization and hydrolysis. Such changes cause both chemical and physical modifications such as esterification, etherification, crystallization, ion-polymer complexation in the polymer. Modified- PVOH structures are useful in biomedical applications.
Application
NaA zeolite particles have been dispersed in a poly(vinyl alcohol) matrix to prepare a mixed-matrix membrane to study the pervaporative separation of water-butanol mixtures. Poly (vinyl alcohol)/gelatin based biocompatible polymeric scaffolds have been used to design for 3D cancer models.
