PVA复合材料的研究进展

Progress of the study on PVA composites

PVA(聚乙烯醇)是由聚醋酸乙烯酯水解而成的一种水溶性聚合物,具有强亲水性、优良的成膜性、可纺性好、并具有较好的力学性能,并且还不易受污染及突出的物理和化学稳定性,具有良好的生物降解性和生物相容性。本文综述了PVA在静电纺丝、相变材料和膜污染三方面的应用展开讨论。

PVA （polyvinyi alcohol） is a kind of water soluble polymers, produced by hydrolyzing the polyvinyl ace- tate , it has strongly hydrophilicity, excellent film-forming, good spinnability, also good mechanical properties. It is not easily polluted by environment, has good ability of physical , chemical stability, good biodegradability and the biocompati- bility. This preview summarized three applications of PVA in the electrospinning, the phase change materials , membrane fouling and some discussions about these.
