Abstract

Cationic starch-based hydrogel was synthesized by simultaneous gamma irradiation of starch (St), acrylamide (AAM), allyl triphenyl phosphonium bromide (APB) and N,N'-methylene bisacrylamide (MBA) as cross-linker in aqueous solution. The molecular mass of the un-grafted AAM/APB copolymer, the cationic degree and the glass temperature (Tg) of the resulting starch-based hydrogel increase with absorbed dose increasing, but no obvious change of thermal stability is observed. Moreover, the swelling equilibrium ratio ( ) of the dry hydrogel decreases with absorbed dose increasing. Gel fraction continually increases with increasing AAM/APB mass ratio, but decreases by increasing starch/(AAM+APB) mass ratio at a fixed absorbed dose of 3 kGy. Se decreases initially and then increased with increasing AAM/APB mass ratio.
