抗菌性聚乙烯醇包装材料的研究进展

Research progress on antibacterial polyvinyl alcohol for packaging

抗菌材料能够有效抑制细菌的生长和繁殖,将其应用于生产生活中,对保护人类健康有着十分重要的意义。安全和环保是目前抗菌包装材料面临的两个主要问题,解决这两个问题将会给包装材料带来更广阔的发展空间。聚乙烯醇(PVA)是一种水溶性高分子材料,具有可降解、生物相容、安全、无毒和环保等特性,在包装材料领域有着广阔的应用前景。但是,PVA材料也存在着耐水性差、水蒸气阻隔性差和抗菌活性低等缺点,难以满足实际生产生活的要求。为了实现PVA在抗菌材料领域的广泛应用,需要对其进行改性以制备具有抗菌性能、高机械性能和耐水性的PVA基复合材料。本文对近年来抗菌性高性能PVA基复合材料进行综述,该材料有望应用于食品和药物包装等领域。

Antibacterial materials can effectively inhibit the growth and reproduction of bacteria.The application of antibacterial materials to life and production is of great significance for the protection of human health.Safety and environmental protection are two main problems for the antibacterial packaging materials,and solving these two problems will bring a boarder development space for these materials.Poly(vinyl alcohol)(PVA)is a kind of water-soluble polymer material,which has the characteristics of biodegradability,biocompatibility,safety,non-toxicity,and environmentally friendly.It has broad application prospects in the field of packaging materials.However,PVA materials also have shortcomings such as poor water resistance,poor water vapor barrier properties,and low antibacterial activity,which are difficult to meet the requirements of actual production and life.In order to broadenthe application of PVA in the field of antibacterial materials,it is necessary to modify it and prepare a PVA-based composite with antibacterial properties,high mechanical properties,and water resistance.In this paper,the antibacterial high-performance PVA-based composites are reviewed in recent years,and the composites are expected to be applied in the fields of food and pharmaceutical packaging.
