The Preparation and Characterization of Carboxymethyl Chitosan Wound Dressings

Abstract:

In order to improve the absorption properties of chitosan wound dressings, this paper used chloro-acetic acid to convert chitosan fibers into partially carboxymethylated chitosan fibers. Fibers with various degrees of carboxymethylation were prepared by controlling the ratio between the weight of fiber and chloro-acetic acid. Results showed that the carboxymethylated chitosan fibers can absorb a large amount of liquid into the fiber structure. When the degree of carboxymethylation is below 50%, the carboxymethylated chitosan fibers can absorb a large amount of liquid whilst maintaining its fibrous struture at the same time.
