Abstract
AbstractThis study reports on the synthesis and characterization of interpenetrating polymeric network (IPN) and polyelectrolyte complexes (PEC) produced by ion‐complex formation between natural and synthetic polymer bearing opposed charge. PEC of sodium alginate (NaAlg) and poly(acryloxyethyl‐trimethylammonium chloride‐co‐2‐hydroxyethyl methacrylate) (poly(Q‐co‐H)) were formed by addition of 2.0 wt % sodium alginate solution to 1.5 wt % poly(Q‐co‐H) solution, and by adding the poly(Q‐co‐H) solution to the NaAlg solution under magnetic agitation. The IPN were prepared using the sequential method with three different compositions, in which Q and H monomers were mixed in the 95/5 proportions in presence of NaAlg. The mixture was polymerized at 60°C using potassium persulfate as initiator. The characterizations of scaffolds were investigated by Fourier‐transform infrared spectroscopy and thermogravimetric analysis. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
