A robust, one-pot synthesis of highly mechanical and recoverable double network hydrogels using thermoreversible sol-gel polysaccharide

Abstract

A new type of physically linked double-network hydrogel is synthesized by a simple, time-saving, facile, easily controlled, one-pot method. The resulting agar/polyacrylamide double-network hydrogels exhibit good mechanical properties, excellent recoverability, and a unique free-shapeable property, which makes them very promising hydrogels for load-bearing soft tissues.

Keywords: double network hydrogels; one-pot synthesis; polysaccharides; recoverable; sol-gel.
