摘要

摘要: 传统塑料的大量使用及其废弃后无法降解给生态环境造成了严重污染，同时也给日益严峻的石化能源造成了巨大压力。薄膜材料是塑料的主要制品之一，其中生物降解薄膜因具有绿色环保、实现碳循环目标等优点，且能够在很大程度上改善全球环境污染和能源短缺的困境，被认为是当前薄膜发展的重要趋势。然而，生物降解薄膜也存在性能不理想、成本较高等问题，其较差的阻隔性更是限制了它在包装方面的应用。本文综述了纳米材料用于生物降解薄膜气体阻隔性的研究现状，主要从纳米材料的种类，组合方式以及生产纳米复合薄膜的加工方式三部分展开介绍，并对生物降解薄膜未来的研究发展做了展望。

Abstract: The extensive use of traditional plastics and their non-degradable nature after disposal has led to severe pollution in the ecological environment and exerted enormous pressure on the increasingly critical petrochemical energy resources. Thin film material is one of the primary plastic products currently in application. The biodegradable films, known for their environmental friendliness and contribution to achieving carbon cycling goals, hold the potential to make substantial strides in mitigating global environmental pollution and addressing energy shortages. However, biodegradable films face challenges such as suboptimal performance and higher costs, with their poor barrier properties particularly limiting their application in packaging films. This article reviews the current research status of nanomaterials for enhancing the gas barrier properties of biodegradable films. The discussion is divided into three main parts: the types of nanomaterials, their combinations, and the processing methods for producing nanocomposite films. The article also provides insights into the future research and development of biodegradable films.
