Preparation and Basic Characterizations of Alginate-Chitosan Hydrogel

Abstract:

The aim of this study is to prepare and characterize an alginate-chitosan hydrogel for wound dressing application. The influence of alginate concentrations (1%, 2%, 3% and 4% (w/v)) was investigated. This polyelectrolyte hydrogel is observed to be transparent and flexible. The SEM morphological structure of hydrogel is composed of a dense outer skin layer and a porous cross-section layer. The FTIR and DSC measurements indicated the protonated amino group of chitosan has reacted with the carbonyl group of alginate. Some other properties for the wound dressing application are also reported in other paper. Taken together these results point out that alginate-chitosan polyelectrolyte hydrogel can be considered for wound dressing applications.
