Structure and properties of cellulose/poly(N-isopropylacrylamide) hydrogels prepared by SIPN strategy

► The cellulose-based hydrogels with various structures were prepared in LiCl/DAMc. ► Semi-interpenetrating polymer network (SIPN) strategy was employed to fabricate the hydrogels. ► The thermo-sensitivity was observed for the hydrogels consisting of cellulose and polyNIPAM. ► The swelling behaviors of the hydrogels depended on the dosage of the cross-linker.
