ESTIMATION OF FIBER-FORMING ABILITY OF CHITOSAN BY PHYSICOCHEMICAL PARAMETERS OF ITS SOLUTIONS

The paper discusses the results of studying the physicochemical properties of a concentrated acetic-acid solution of chitosan with a stabilized agent added (0.05% of the solution weight), which enables a high fiber-forming ability of the polymer to be revealed. The process of fiber formation from chitosan solution under the action of an electric high-intense field was estimated qualitatively and quantitatively. Chitosan fibers with an average diameter of 280 nm have been obtained, their size-distribution function has been plotted.
