水凝胶的制备研究进展

Research progress on preparation of hydrogel

简要介绍了水凝胶的结构、性质及应用情况,从化学交联、物理交联两个方面阐述了水凝胶的制备方法。详细介绍了由自由基聚合、辐射聚合、水溶性高分子的交联和互穿聚合物网络4种化学交联方法,以及通过离子间相互作用、结晶交联作用、氢键作用、疏水缔合作用4种相互作用力来实现物理交联的方法。并对水凝胶未来的研究方向及应用前景进行了展望。

In this paper, the structure, properties and application of hydrogel were introduced. The preparation motheds of hydrogel were described from two aspects of chemical crosslinking and physical crosslinking. The chemical crosslinking method was focused on free radical polymerization, radiation polymerization, crosslinking wa-ter soluble polymer and interpenetrating polymer network. And the physical cross-linking method was focused on ionic interaction, crystal cross-linking, hydrogen bonding interaction and hydrophobic association. The research di-rection and application prospect of hydrogel were provided.
