Title:
METHOD FOR PRODUCING ELECTROCONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2019/031063
Kind Code:
A1
Abstract:
This method for producing an electroconductive film comprises: a liquid composition preparation step for preparing a liquid composition containing an electroconductive agent, an elastomer, and a solvent, the electroconductive agent having thinned graphite in which thin layers of graphite are formed and which has a bulk density of 0.05 g/cm3 or lower; a delamination treatment step for performing interlayer delamination of the thinned graphite by pressurizing the liquid composition and passing same through a nozzle; and a hardening step for coating a substrate with the delamination-treated liquid composition and hardening the coating. This method of production makes it possible to proceed with adequate thinning of the graphite and perform the thinning process in a shorter length of time than conventionally possible, and makes it also possible to produce an electroconductive film that has high electroconductivity and has electrical resistance unlikely to increase even after repeated extension.
