## Abstract An ionically crosslinked polymer network composed of chitosan and sodium hexametaphosphate (SHMP) was synthesized to determine their swelling and ascorbic acid release kinetics at various SHMP concentrations. The chitosan/SHMP hydrogels were synthesized using an acetic acid aqueous solu
Four types chitosan-based hydrogels have been prepared: cross-linked chitosan (cr-CS), cross-linked chitosan interpenetrating polyether polymer network (cr-CS/PE semi-IPN), cocross-linked chitosan and gelatin hybrid polymer network (CS/Gel HPN), and Chitosan/ Pectin (CS/Ptn) ionic complex hydrogels.
The present paper reveals the potential uses of novel hybrids of chitosan-g-lactic acid and sodium montmorillonite (MMT) in controlled drug delivery and tissue engineering applications. The drug-loaded novel nanohybrid films and porous scaffolds have been prepared by solvent casting and freeze-dryin
