摘要：
Polyvinyl alcohol (PVA) has become one of the most widely used hydrophilic membrane materials because of its good chemical stability, acid resistance, alkali resistance and organic solvent resistance, as well as excellent film-forming property and biological safety. However, the weak mechanical properties and poor water resistance of hydrophilic PVA membrane seriously limit its practical applications. In recent years, a lot of studies have been carried out to promote the properties of PVA membrane by blending, nanocomposite, heat treatment, chemical crosslinking and synergistic modifications, which have achieved great success. In this paper, the characteristics and existing problems of different PVA membrane modification methods were summarized, and the research status of excellent fillers in improving the mechanical properties of PVA membrane by nano-composite was emphasized. Also, the effects of blending, heat treatment and chemical crosslinking for the modification of PVA membrane were briefly introduced, and the significance of synergistic modification to improve the comprehensive properties of PVA membrane was stressed. This paper would provide a novel perspective for the design and preparation of high-performance PVA membrane. The modified PVA membrane had a good application prospect in the fields of water treatment and food packaging. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
