Abstract Covalently cross-linked based polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) hydrogel was developed by the cross-linking between PVA and CMC in the presence of catalyst without using any cross-linker. A comparative study of polymeric hydrogel, PVA and CMC was carried out in term of thermal stability, water absorption behaviour in different pH and temperature. The result of TGA indicates that the thermal stability of polymeric hydrogel is improved as compared to non cross-linked polymer. Further, in this study, we revealed that how the water absorption capacity (WAC) of a polymeric network hydrogel affects by ester-linkage.

研究酯键对聚乙烯醇/羧甲基纤维素基水凝胶性能的影响

摘要 共价交联基聚乙烯醇/羧甲基纤维素（PVA/CMC）水凝胶是通过PVA和CMC在催化剂存在下不使用任何交联剂进行交联而开发的。对聚合物水凝胶、PVA 和 CMC 在不同 pH 和温度下的热稳定性、吸水行为进行了比较研究。TGA 的结果表明，与非交联聚合物相比，聚合物水凝胶的热稳定性有所提高。此外，在这项研究中，我们揭示了聚合物网络水凝胶的吸水能力 (WAC) 如何受酯键的影响。
