摘要
水凝胶是由亲水性聚合物链在水性微环境中交联而成的三维立体网状结构,因其良好的溶胀性能,被广泛应用于生物医学、食品科学、农业等领域。以明胶为原料制备的水凝胶具有刺激响应性、生物相容性、可降解性的优势,然而,其力学性能的不足,限制了其进一步应用。所以探究明胶基水凝胶的制备策略,以克服其力学性能短板并赋予其更多元化的功能特性具有重要意义。本文总结了通过不同交联手段制备不同功能特性的明胶基水凝胶的方法,为明胶基水凝胶性能的改进提供了新思路。
Hydrogels,constructed as three-dimensional networks of hydrophilic polymer chains crosslinked within aqueous microenvironments,are widely utilized in various fields such as biomedical,food science,and agriculture due to their exceptional swelling properties.Hydrogels derived from gelatin exhibit advantages like stimulus responsiveness,biocompatibility,and biodegradability.However,their limited mechanical properties hinder further applications.Consequently,exploring preparation strategies for gelatin-based hydrogels to overcome their mechanical shortcomings and endow them with more diversified functional properties is of great significance.This article summarizes various crosslinking approaches used to produce gelatin-based hydrogels with distinct functional characteristics,offering novel insights into enhancing the performance of these hydrogels.
