METHOD FOR PRODUCING THE WATER SOLUTION OF POLYANILINE Russian patent published in 2018 - IPC C08G73/02 C08G8/16 C08G12/00 B82B3/00 H01B1/00 H01B1/04 

FIELD: chemistry.

SUBSTANCE: present invention refers to the method for the preparation of aqueous solutions of polyaniline, as well as to the method for producing multicomponent composite graphene materials based on polyaniline. Method comprises treating the polyaniline with the aqueous solution of the phenol-formaldehyde resin (FFR) of the resole type. Polyaniline is used in the form of the base. Weight ratio of phenol formaldehyde resin to polyaniline is from 0.25:1 to 2:1. Method for producing composite materials based on polyaniline comprises preparation of aqueous dispersions of components stabilized by FFR, mixing of aqueous dispersions of components and coagulation of the mixture by lowering the pH parameter.

EFFECT: above stated method allows to impart solubility to the polyaniline in water and in conventional organic solvents, which in its turn makes it possible to process this polymer and make various composite materials and products from it.
