Swelling behavior of novel protein-based superabsorbent nanocomposite
(1170–1179)Journal of Applied Polymer  Science 120 #2 (2011)
Marandi et al synthesized asuperabsorbent nanocomposite by simultaneously graft copolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and acrylamide (AAm).  Sodium montmorilonite (Na-MMt) was used as clay. Methylenebisacrylamide (MBA) and ammonium persulfate (APS) were used as crosslinker and initiator, respectively.  Inclusion of Na-MMt nanoclay causes an increase in water retention under heating.  (RDC 1/10/2011)
