In situ polymerization of acrylamide–bisacrylamide mixture in concentrated aqueous gelatin solutions followed by the subsequent crosslinking of gelatin itself with glutaraldehyde yields interpenetrating hydrogel networks. The surface morphology, swelling, and thermal behavior of the samples of different composition were investigated. The swelling characteristics of the hydrogel could be manipulated by varying gelating and acrylamide ratio.
