Temperature-sensitive chitosan-poly(N-isopropylacrylamide) interpenetrated networks with enhanced loading capacity and controlled release properties.

Abstract

Interpenetrated polymer networks (IPN) of poly(N-isopropylacrylamide) (PNIPA) and chitosan (two grades) were prepared by free radical polymerisation and cross-linking of PNIPA (700 mM) with bis(acrylamide) (20 mM) in chitosan solutions (1.5 wt.% in acetic acid), and subsequent immersion in glutaraldehyde solutions (0 to 0.7 vol.%) to post-cross-link the… (More)
