Synthesis and characterization of membranes obtained by graft copolymerization ...
Santos, K. S. C. R. dos; Coelho, J. F. J.; Ferreira, P.; Pinto, I.; Lorenzetti, S. G.; Ferreira, E. I.; Higa, O. Z.; Gil, M. H.Chitosan based membranes to be applied on wound healing as topical drug delivery systems were developed by graft copolymerization of acrylic acid (AA) and 2-hydroxyethyl methacrylate (HEMA) onto chitosan using cerium ammonium nitrate as chemical initiator. Evidence for graft copolymerization of the vinyl monomers onto chitosan was obtained by FTIR and DMTA. Swelling degree, cytotoxicity, thrombogenicity and hae...
