METHOD OF PRODUCING ELECTROCONDUCTIVE PAPER BASED ON FIBROUS CRYSTALS OF VANADIUM BRONZES Russian patent published in 2011 - IPC D21H27/00 D21H13/46 D21H13/48 

FIELD: chemistry.

SUBSTANCE: invention relates to electroconductive paper and a method of making said paper (versions). The electroconductive paper consists of fibrous crystals of BaV₈O₂₁ with length of 0.5-3 mm and thickness of 0.1-10 mcm, interlaced between each other into an electroconductive mass. One method of making the electroconductive paper involves holding xerogel plates in saturated aqueous solution of Ba(NO₃)₂ for 8-48 hours and then hydrothermal treatment at 150-200°C for 8-48 hours. The plates are then dried in a drying cabinet at 70°C for 8 hours. In another version of the method, xerogel plates are held for not less than 48 hours and the specimen can be freeze dried for 24 hours at pressure 133-10^-3 mbar at temperature between -196°C and 0°C.

EFFECT: obtaining electroconductive paper with good mechanical and stable electrochemical properties.
