FUNCTIONALIZING POROUS MATERIALS BASED ON ISOCYANATE Russian patent published in 2019 - IPC C08J9/28 C08G18/82 C08J9/36 

FIELD: chemistry.

SUBSTANCE: invention relates to the synthesis of organic porous materials based on isocyanate. Functionalized organic aerogel/xerogel/isocyanate-based cryogel is proposed that has hydrophobicity and contains a crosslinked porous network structure made of polyurethane and/or polyisocyanurate and/or polyurea, containing reactive groups (B) on its surface that are able to bind with the formation of a covalent bond with reactive groups (A) present in functionalizing molecules, and functionalizing molecules having solubility in water <0.1 g/l at 20 °C, chemically attached to the surface of the pores of a crosslinked porous mesh structure, moreover, these molecules have at least one reactive group (A) that can bind to the specified surface of the pores (through interaction with groups (B)), and at least one functional group (C), providing the surface of pores with the necessary functionalization. Method of obtaining the claimed aerogel/xerogel/cryogel and its application is also proposed.

EFFECT: proposed aerogel/xerogel/cryogel gives the materials hydrophobicity, without compromising the processability of the materials.
