食品包装材料对保持食品质量至关重要，因为它们在防止食品变质、脱水和氧化方面发挥着重要作用。与合成聚合物不同，天然生物聚合物，如多糖和蛋白质，是无毒，生物相容性和生物可降解的丰富和广泛的资源。在食品包装中，包装材料与潮湿食品之间的接触经常会降低材料的性能。这增加了对基于疏水生物聚合物的膜的开发的研究。在这里，我们总结了有效的制备策略，机械和阻隔性能，pH响应性，自清洁性能，抗菌和抗氧化功能的疏水生物聚合物为基础的薄膜。制备疏水性生物聚合物基膜的最有效方法是用疏水改性的生物聚合物进行静电纺丝，向膜中添加微米/纳米填料和疏水化合物，并对膜进行疏水改性。这些方法甚至可以产生具有优异阻隔性能的超疏水膜。我们还讨论了目前的机遇和挑战所提出的疏水性生物聚合物为基础的薄膜。
Food packaging materials are crucial to maintaining food quality, as they play an important role in preventing food deterioration, dehydration, and oxidation. Unlike synthetic polymers, natural biopolymers, such as polysaccharides and proteins, are abundant and widespread resources that are nontoxic, biocompatible, and biodegradable. In food packaging, contact between packaging materials and moist foods can frequently degrade the performance of the materials. This has increased research into the development of hydrophobic biopolymer-based films. Here, we summarize the effective preparation strategies, mechanical and barrier properties, pH responsiveness, self-cleaning performance, and antibacterial and antioxidant functions of hydrophobic biopolymer-based films. The most effective methods for preparing hydrophobic biopolymer-based films are electrospinning with hydrophobically modified biopolymers, adding micro/nanofillers and hydrophobic compounds to the films, and hydrophobically modifying the films. These methods can even generate superhydrophobic films with excellent barrier properties. We also discuss the current opportunities and challenges presented by hydrophobic biopolymer-based films.
