摘要: 受贻贝可以在潮湿环境中牢固粘附于介质表面现象的启发,研究者们在明确了儿茶酚基团在贻贝黏附过程中的重要作用之后,据此开发出多种仿贻贝的儿茶酚基功能材料。本文主要介绍了近年来利用儿茶酚结构对壳聚糖、透明质酸、海藻酸盐、蛋白质、多肽、明胶等天然生物大分子进行接枝改性,进而通过与金属离子的配位交联作用,开发多功能水凝胶的研究进展。

Abstract: Inspired by the phenomenon that mussels can adhere firmly to the surface of media in the wet environment, researchers have identified the important role of catechol groups in the adhesion process of mussels. Thus, scientists have developed a variety of mussel-like catechol-modified hydrogel functional materials. Herein, this review summarizes the most recent progress in the fabrication of catechol-modified multifunctional biomacromolecule hydrogels crosslinked by coordination with metal ions, and the discussed biomacromolecules involve chitosan, hyaluronic acid, alginate, protein, polypeptide and gelatin. Focus is on the modification of biomacromolecules by catechol groups, fabrication method, gelling mechanism, multifunctionality and potential application of these hydrogels.

Key words: catechol, dopamine, biomacromolecule, coordination crosslinking, hydrogels
