Abstract

Poly(vinyl alcohol) (PVA)–phosphotungstic acid (PTA) nanocomposite films were prepared from aqueous solutions with added ethylene glycol (EG), which is a plasticizer for PVA and contains OH groups, capable of being electron donors in the photoreduction of PTA. Spectroscopic studies have shown that the addition of EG significantly enhances the photochromic properties of the resultant nanocomposites due to photoinduced electron transfer from the organic matrix of the nanocomposite to PTA molecules.

使用低分子量酒精添加剂增强聚乙烯醇-磷钨酸纳米复合材料的光致变色性

聚乙烯醇（PVA）-磷钨酸（PTA）纳米复合薄膜是由添加了乙二醇（EG）的水溶液制备而成的，乙二醇是 PVA 的增塑剂，含有 OH 基团，能够在 PTA 的光诱导过程中作为电子供体。光谱研究表明，由于光诱导电子从纳米复合材料的有机基质转移到 PTA 分子，添加 EG 显著增强了所制备纳米复合材料的光致变色特性。
