Dual crosslinked carboxymethyl cellulose/polyacrylamide interpenetrating hydrogels with highly enhanced mechanical strength and superabsorbent properties

Carboxymethyl cellulose (CMC)-based hydrogels possess superabsorbent properties and are biocompatible; however, their use is limited because of their low mechanical strength. In the present study, we used a sequential dual crosslinking strategy to produce new CMC-based interpenetrating polymer ne…
