Abstract

The present invention discloses a method for strong and tough bonding of trehalose-modified hydrogels and a method for dehydration-induced strengthening. The bonding performance of traditional hydrogels tends to decrease under dehydration or extreme environments, which limits their application in biomedicine and electronic equipment. The present invention introduces trehalose and utilizes its polar groups to induce the formation of strong hydrogen bonds, thereby significantly enhancing the bonding strength between the hydrogel and the interface of different materials, and achieving strong and tough bonding of the hydrogel under dehydration or extreme environments. In addition, the present invention controls the dehydration process of the hydrogel, so that the free water in the hydrogel gradually decreases and the proportion of bound water increases, thereby forming a network structure with stronger interaction, further improving the bonding strength. The present invention is suitable for high-strength bonding requirements in harsh environments, can improve the long-term use reliability and environmental adaptability of devices such as hydrogel supercapacitors, and has broad application prospects.
