Polysaccharides and proteins are abundantly found in nature and are highly recommended for developing eco-friendly materials due to their special properties (biodegradability, biocompatibility, non-toxicity, low cost, etc.). However, they sometimes fail to meet specific requirements due to poor mechanical and physical properties. Poly(vinyl alcohol) (PVA) is one of the promising synthetic polymers with superior properties that can be blended with natural polymers for obtaining novel biomaterials with improved performances. This review addresses recent advance in PVA/polysaccharides and PVA/proteins biocomposites design and fabrication, mainly for the past two decades.

聚乙烯醇和天然聚合物的生物材料

多糖和蛋白质在自然界中被广泛发现，并因其特殊的特性（生物降解性，生物相容性，无毒性，低成本等）而被强烈推荐用于开发环保材料。但是，由于机械和物理性能较差，它们有时无法满足特定要求。聚乙烯醇（PVA）是一种有前途的合成聚合物，具有优异的性能，可以与天然聚合物共混以获得具有改进性能的新型生物材料。这篇综述主要针对过去二十年来PVA /多糖和PVA /蛋白质生物复合材料设计和制造的最新进展。
