MANUFACTURING METHOD OF ULTRA-HIGH CONDUCTIVITY FLEXIBLE TRANSPARENT COPPER FILM AND COPPER FILM MANUFACTURED THEREFROM

摘要

The present invention relates to a manufacturing method of an ultra-high conductivity flexible transparent copper film, and to a copper film manufactured therefrom. In the manufacturing method, ink in which nano-silver particles are dispersed is coated on a desired base material film to form a silver pattern. And, by performing clear resin coating on the silver pattern, coating only a protruding upper layer portion of the silver pattern to be exposed to the outside, and then electroplating copper onto the silver pattern, a transparent thin film is performed while fiberization of pure copper is made around the upper layer portion of the exposed silver pattern, and the formed transparent thin film is separated from the silver pattern.;COPYRIGHT KIPO 2019
