Description

technical field [0001] The invention relates to the technical field of conductive ink, in particular to a conductive ink composite material. Background technique [0002] Conductive ink is a conductive composite material formed by dispersing metal conductive particles (silver, copper, carbon, usually silver) in a binder. After printing on the substrate, it acts as a wire, antenna and resistor. Conductive ink is the most basic and critical raw material for the production of organic printed circuit boards (thin films). One of the key raw materials for the success of organic printed electronic products. [0003] Many of the existing conductive inks are composed of noble metal conductive particles, which are expensive, and other metal powders except silver powder are easy to oxidize and reduce the conductivity. Although the conductive ink of carbon powder is low in cost, its conductivity is poor, which limits its application. Contents of the invention [0004] The purpose o...
