FIELD: chemistry.
SUBSTANCE: group of inventions refers to chemistry of high-molecular compounds, concerns versions of method for producing chitosan sponge, which can be used in medicine as wound coatings, haemostatic materials, matrices for fabric engineering. Chitosan sponge production method involves dissolving chitosan in an aqueous solution of acetic acid, hydrochloric acid or lactic acid. After complete dissolution of chitosan while stirring, a foaming agent is added. Foaming agent used is sodium bicarbonate, potassium bicarbonate or ammonium hydrocarbonate. Then, obtained sponge is washed from residues of acid and foaming agent, and dried jaw is dried. Components are used in mentioned ratio.
EFFECT: group of inventions provides simplification of synthesis and expansion of application area of obtained sponge due to possibility of controlling speed of its production and porosity.
