多功能型明胶黏合剂的制备及应用研究进展

明胶是由胶原蛋白水解得到的一类聚合物，作为一种具有良好生物相容性和生物降解性等生物学性能的天然高分子材料，因其具有良好的发泡性、乳化性和成膜性等特点，在产品包装、增稠、充当递送载体等方面被广泛应用。本文就明胶凝胶强度、黏度、颜色、产量、等电点等理化性质及其影响因素，以及明胶不同类型的改性、交联方式和制备各种功能性明胶基水凝胶进行综述。通过设计使用不同材料，引入不同官能团来合成不同功能特性的明胶复合水凝胶黏合剂，以丰富其在日常生活中的应用，为明胶的提取及综合利用提供一些新的思路。

Recent Progress in Preparation and Application of Multifunctional Gelatin Adhesives

Gelatin is a polymer derived from the hydrolysis of collagen. As a natural polymer material with good biocompatibility and biodegradability, gelatin has been widely used in product packaging and thickening and as a delivery carrier due to its good foaming, emulsifying and film-forming properties. In this paper, the physicochemical properties of gelatin such as gel strength, viscosity, color, yield and isoelectric point and the factors influencing them are reviewed, as well as the modification of different types of gelatin, the types and ways of cross-linking of gelatin and the preparation of various functional gelatin-based hydrogels. Gelatin composite hydrogel adhesives with different functional properties can be synthesized by introducing different functional groups into different artificially designed materials, which can enrich the application of gelatin in daily life and provide some new ideas for the extraction and comprehensive utilization of gelatin.
