NANOCOMPOSITE AND METHOD OF ITS PRODUCTION Russian patent published in 2005 - IPC

FIELD: production of new materials.

SUBSTANCE: proposed nanocomposite can be used as component contributing to charges of consumer properties of materials made on its base. Nanocomposite includes fibrils of filler-chitin individualized to nanosizes with distance between fibrils from 709 to 20-22 nm and water-soluble polymeric matrix in interfibril space. Degree of filling of nanocomposite is 0.05-0.25% mass. Fibrils are arranged in parallel and they have cross size of 4 nm. Method of production of nanocomposite comes to the following: free-radical polymerization in water medium of at least one monomer of row of acrylic acid, salt of acrylic acid, acrylamide is carried out in presence of filler. Initiator is chosen from the row of water-soluble peroxides, hydroperoxides or their salts, potassium persulfate. Individualization to nanosizes of fibrils is done simultaneously with process of polymerization and/or with combination of said process with mechanical disintegrating action by disintegrating or pressing, or pressing with abrasion shift. Nanocomposite is obtained in form of film, being pervaporation membrane.

EFFECT: enlarged range of filling, ease of production.
