摘　　要：采用浸渍提拉溶液共混法制备出聚乙烯醇/焦磷酸铈(PVA/CeP2O7)复合膜。对薄膜进行了人工紫外老化,并对不同老化时间纯PVA膜和复合膜的力学、水蒸气透过、耐水耐油等性能进行了测试,使用紫外-可见分光光度计、紫外-可见光谱仪和热重分析仪进行了分析。结果表明,PVA/CeP2O7复合膜抗紫外老化性能良好,且力学性能、热稳定性、耐水性、保湿性较纯PVA膜都有所提高,耐油性保持良好。Polyvinyl alcohol/cerium pyrophosphate composite films were prepared by solution blending and dip-coating method.Artificial accelerate ultraviolet experiment of this composite films was conducted.The UV spectra and mechanical properties analysis of cerium pyrophosphate/PVA composite films with different aging time proved that the composite films had the function of anti-ultraviolet radiation and its mechanical property remained well after the UV aging.Thermo gravimetric,water vapor transmission,water resistance and oil resistance of cerium pyrophosphate/PVA composite films were studied which showed that properties of the cerium pyrophosphate/PVA were better than the pure PVA films.
