摘要
主要介绍了水溶性聚乙烯醇（PVA）／TiO2杂化膜作为包装材料具有的一些优异性能和用途，从发展现状、制备方法和用途三方面对PVA／TiO2杂化膜进行了归纳总结，并分析了PVA／TiO2杂化膜现阶段所存在的问题。PVA材料的亲水性、环保性、生物相容性及纳米TiO2的亲水性、光照后不发生光腐蚀、耐酸碱性、化学稳定性和对生物无毒性等特点将赋予PVA／TiO2杂化膜广泛的应用前景。
The polyvinyl alcohol（ PVA）/TiO2 film as a kind of packaging materials was mainly introduced, which had many excellent properties and extensive applications. The PVA/TiO2 film＇ s development status, sol＇ s preparation, technical process and the use were described. Some problems of PVA/TiO2 film in recent years were also analyzed. PVA/ TiO2 film had a broad application prospect because of its merits of both PVA and TiO2.
