Abstract：
Hydrogels is a hydrophilic, cross-linked polymer of three-dimensional network structures. The application of hydrogels prepared from a single polymer in the biomedical field has many drawbacks. The functional blend of polyvinyl alcohol and chitosan allows hydrogels to have better and more desirable properties than those produced from a single polymer, which is a good biomaterial for development and design. In this paper, we have reviewed the progress in the application of polyvinyl alcohol/chitosan composite hydrogels in various medical fields, the different cross-linking agents and cross-linking methods, and the research progress in the optimization of composite hydrogels for their subsequent wide range of biomedical applications.
摘要：
水凝胶是一种亲水性,三维网络结构的交联聚合物。由单一聚合物制备的水凝胶在生物医学领域中的应用具有许多缺点。聚乙烯醇和壳聚糖的功能性共混物使水凝胶比由单一聚合物生产的水凝胶具有更好和更理想的性能，这是开发和设计的良好生物材料。在本文中,综述了聚乙烯醇/壳聚糖复合水凝胶在医疗领域的应用进展,不同的交联剂和交联方法，以及优化复合水凝胶在其后续广泛的生物医学应用方面的研究进展。
