Abstract

Super-tough polyacrylamide/iota-carrageenan double-network hydrogel was strengthened by micro-scaled bacterial cellulose nanofibrous particle. The intermolecular hydrogen bonds and topological interlock effectively improved the strength. Such hydrogels were able to stretch over 27 times of initial length, or undertook over 200 kPa of tensile stress, and the toughness reached a high value of ~2000 kJ/m³. By drying and reswelling method, we further enhanced the strength through hydrogen bonds. By extension-drying and post-annealing method, we prepared a strong PAM/IC/BC-1 hydrogel strand with shape memory.
