The environmental crisis caused by the use of petroleum-based nondegradable polymers and the impending petroleum finite resources have directly threatened human being's sustainable development. Therefore, ecofriendly polymers based on natural renewable resources are attracting more and more attention. As the byproducts of soy oil industries, soy protein, is regarded as a viable alternative for petroleum-based polymeric products. In order to improve the physical properties, especially the mechanical properties and water resistance that limit their extensive applications, different modifications were adopted. Among these efforts, incorporating nanoparticles and blending with other polymers are proved to be effective ways. The properties of the resulting materials are highly dependent on the processing methods, nature of the components, dispersion status and the compatibility. This review intends to provide a clear overview on preparation, properties, and applications of soy-protein-based materials. These biodegradable materials will find more and more potential applications in biodegradable foams, edible films, packaging materials, biomedical materials, etc.
由石油基不可降解聚合物的使用所导致的环境危机以及即将耗尽的石油资源已直接威胁到人类的可持续发展。因此,基于天然可再生资源的环保型聚合物越来越受到关注。作为大豆油工业的副产品,大豆蛋白被视为石油基聚合产品的可行替代品。为了改善物理性能,特别是限制其广泛应用的机械性能和耐水性,采用了不同的改性方法。在这些努力中,掺入纳米粒子和与其他聚合物共混已被证明是有效的方法。所得材料的性能高度依赖于加工方法、组分的性质、分散状态和相容性。本文综述了基于大豆蛋白的材料的制备、性能和应用。这些生物降解材料将在可生物降解泡沫、可食用薄膜、包装材料、生物医学材料等领域得到越来越多的潜在应用。
