AB - A composite superabsorbent material was synthesized based on silk sericin, acrylic acid and acrylamide
by using N, N-methylenebisacrylamide (MBA) as the crosslinker and ammonium persulfate (APS) as the
initiator reagent. The water absorbency and water retaining properties of the composite under different
preparation conditions were investigated. The absorbency of silk sericin / acrylic acid / acrylamide
(SS/AA/AM) superabsorbent polymer polymer in deionized water, tap water and 0.9% NaCl solution
were 285337 g/g, 191220 g/g, 3643g/g, respectively. SS/AA/AM material has excellent re-absorbent
abilities and can be reused. The product showed different water absorbency in aqueous chloride salt
solutions with the order of Na^+ > Ca^{2+} > Mg^{2+} > Al^{3+}. FTIR spectra results indicated that silk
sericin was successfully grafted with acrylic acid and acrylamide molecules. The study on the absorbent
material based on sericin is useful for further research on biodegradable superabsorbent polymer.
