MULTIFUNCTIONAL COATS ON MICROPOROUS CARRIERS Russian patent published in 2011 - IPC B01D71/36 B01D69/02 B01D67/00 C08J7/04 B01D71/32 

FIELD: process engineering.

SUBSTANCE: invention relates to composite materials, method of producing multifunctional coat on microporous carrier to be used in many fields exploiting properties of both microporous carrier and coat material. Proposed composite material comprises microporous layer having pore walls and apparent porosity and multifunctional coat of two or more functions on at least a portion of microporous layer pore walls. Microporous layer preserves at least a definite portion of apparent porosity on a section of coated microporous structure. Proposed method comprises producing mix for water wetting, adding first additive to said mix and at least one additional functional additive. It comprises also applying said wetting solution on microporous structure and heating microporous material containing said wetting mix with two or more functions wherein microporous layer preserves at least a definite portion of apparent porosity on a section of coated microporous structure.

EFFECT: method of producing multifunctional coat on microporous carrier to be used in many fields exploiting properties of both microporous carrier and coat material.
