Abstract: Currently, chitosan (CTS) or chitosan derivatives hydrogels are applied in different fields, such as biological materials, medical materials and hygiene materials. In this study, novel chitosan hydrogels were successfully prepared by chitosan and poly(amidoamine) (PAMAM) dendrimer with glutaraldehyde serving as a cross-linking agent. Fourier transform infrared spectroscopy (FTIR), (1)H nuclear magnetic resonance ((1)H NMR) and gel permeation chromatography (GPC) were performed to characterize PAMAM. The struct…
