Carrageenan, a polysaccharide extracted from marine algae, is becoming increasingly regarded as a promising renewable biomaterial that has strong potential as a substitute for conventional synthetic plastics. Materials derived from carrageenans have been widely investigated over the recent decades for use in pharmaceutical and biomedical applications through to edible films and coatings. In the area of flexible films, carrageenans suffer from limitations that are primarily a result of their inherent hydrophilicity. Considerable research efforts have been devoted to the improvement of the properties of carrageenan films in order to extend the range of suitable applications. These include blending with other polymers, the use of plasticizers, and reinforcements with nanomaterials. This review comprehensively assesses the current status of carrageenan-based film development including material characteristics and strategies to obtain desirable film properties with particular regard to real applications.
角叉菜胶是一种从海藻中提取的多糖，越来越被视为一种有前景的可再生生物材料，具有很强的潜力可替代传统合成塑料。近几十年来，源自角叉菜胶的材料已被广泛研究，用于制药和生物医学应用直至可食用薄膜和涂层。在柔性薄膜领域，角叉菜胶存在局限性，这主要是其固有亲水性的结果。为了扩大合适的应用范围，人们投入了大量研究工作来改善角叉菜胶薄膜的性能。这些方法包括与其他聚合物共混、使用增塑剂以及用纳米材料增强。本综述全面评估了基于角叉菜胶的薄膜开发现状，包括材料特性以及获得理想薄膜性能的策略，特别关注实际应用。
