摘要
聚乙烯醇(PVA)的化学稳定性及成膜性较好,可以完全生物降解,与天然高分子材料的相容性好,已被广泛应用于与天然高分子材料复合制备可生物降解材料。综述了淀粉/PVA复合材料、纤维素/PVA复合材料、壳聚糖/PVA复合材料、木质素/PVA复合材料及蛋白质/PVA复合材料的研究进展,并对其作为可生物降解材料替代某些通用塑料的应用前景进行了展望。
As a fully degradable polymer, polyvinyl alcohol (PVA) is widely used in the preparation of natural polymer composite biodegradable materials with good chemical stability, filming properties and biocompatibility. The research progresses of starch/PVA materials, cellulose/PVA materials, chitosan/PVA materials, lignin/PVA materials and protein/PVA materials are reviewed, and the prospect of biodegradable composites substituting for some traditional plastics is proposed as well.
