Institute of Chemistry develops highly elastic hydrogel materials

Recently, researchers from the Institute of Chemistry, Chinese Academy of Sciences, from the perspective of polymer/nanoparticle interaction regulation, introduced highly branched silica nanoparticles into a moderately chemically cross-linked polymer glue network to develop A class of pure elastic nanocomposite hydrogel materials with high water content has been developed

Polymer hydrogels, as a class of macromolecular three-dimensional networks formed by chemical cross-linking or physical interactions, exhibit excellent biocompatibility due to their high water content similar to biological tissues, and are widely used in tissue engineering, drug release, etc.

Under the condition of 96% water content, the nanocomposite hydrogel exhibits up to 11.

Based on the unique pure elastic mechanical behavior of such materials, the research also constructs an ionic strain sensor to achieve high-sensitivity detection of tiny vibrations
