摘　　要：聚乙烯醇(PVA)膜具有出色的生物相容性及生物降解性,良好的机械性能以及优异的阻隔性等优点.被广泛用在抗菌抑菌、柔性光电器件、气体阻隔等多个领域。然而,其具有极易被引燃且在燃烧过程中会释放不饱和醛酮类有毒气体等问题,导致在使用过程中产生较大安全隐患,限制了其广泛应用,需要将其制成复合材料以提升其阻燃性能。近年来,无卤纳米阻燃材料在PVA阻燃复合膜中发展较为突出,低负载量的纳米阻燃PVA复合膜即可显著提升阻燃效果.其中阻燃填料不同的微观形貌及不同元素阻燃体系对膜的阻燃效果存在差异。因此,本文依据PVA膜无机类纳米阻燃填料微观形貌及阻燃体系,从二维(金属氢氧化物系、磷系、碳系、陶瓷及黏土体系)和非二维纳米材料概述了PVA复合膜阻燃的发展现状与阻燃机制,并展望了PVA复合膜阻燃的发展趋势。With excellent biocompatibility, biodegradability, good mechanical properties and excellent barrier properties, poly(vinyl alcohol) membranes are widely used in the fields of antibacterial and bacteriostatic, photoelectric devices, gas barrier, etc. However, it’s easy to be ignited and will release unsaturated aldehydes and ketones in the combustion process, leading to great safety risks during use, which limits its wide application. Therefore, it needs to suffer flame retardant modification treatment. In recent years, the development of nano-flame retardant materials in PVA flame-retardant composite film is outstanding. The flame retardant effect of nano-PVA composite membrane with low load can be significantly improved. The flameretardants with different micro-morphologies and different flame-retardant systems have difference in PVA composites films. Based on the micro-morphology of nano-flame retardant fillers of PVA films and system of flame-retardant, the development and flame-retardant mechanism of PVA composite film are summarized from 2 D nanomaterials(metal hydroxide, phosphorus, carbon, ceramic and clay) and non-2 D nanomaterials, and the development trend of flame retardancy of PVA composite film is also prospected.
