Preparation of Polyvinyl Alcohol/Sodium Alginate Composite Hydrogel and Its Performance Study
摘要: 本论文以四硼酸钠为交联剂，通过化学交联法和冻融法制备聚乙烯醇(PVA)/海藻酸钠(SA)/聚吡咯(PPy)光热复合水凝胶。采用接触角测量仪、红外热像仪、傅里叶红外光谱仪、力学拉伸机等对复合水凝胶进行测试与表征。结果表明：在PVA中引入SA有助于形成紧密的三维网络互穿结构，力学性能显著提高；PPy的加入提高了复合水凝胶的光热转化效率，同时还具有增加吸水率，进一步改善了力学性能的特点。
Abstract: In this thesis, polyvinyl alcohol (PVA)/sodium alginate (SA)/polypyrrole (PPy) photothermal composite hydrogels were prepared by chemical cross-linking method and freeze-thawing method using sodium tetraborate as cross-linking agent. The composite hydrogels were tested and characterised using contact angle measurement instrument, infrared thermography, Fourier infrared spectroscopy and mechanical stretching machine. The results showed that the incorporation of SA into PVA helped to form a compact three-dimensional network interpenetrating structure and improve the mechanical properties of PVA; the incorporation of PPy increased the efficiency of photothermal conversion, and also increased the water absorption rate, which further improved the mechanical properties.
