摘　　要：双网络水凝胶在保持高吸水性等性能的基础上改善了传统水凝胶机械性能差、不稳定等缺点。重点介绍了双网络水凝胶及其在组织工程、伤口敷料、离子吸附、农林业等方面的应用。当在组织工程、导电和伤口敷料等医学领域应用时,水凝胶的生物相容性及力学性能成为研究重点;当应用在林业和吸附染料、离子方面时,水凝胶的溶胀性能较为重要。Compared with traditional hydrogels,double-network hydrogels show the improved mechanical properties and better stability on the premise of maintaining high absorbency and other properties.This review focuses on the double network hydrogels and their applications in tissue engineering,wound dressings,ion adsorption,agriculture and forestry.Biocompatibility and mechanical properties of hydrogels are the focus of research when they are used in tissue engineering,electrical conductivity and wound dressings,and the swelling property of hydrogels is more important in forestry,and adsorbing dyes and ions.
