Abstract

The invention discloses graphene-based conductive ink and a preparation method thereof. The preparation method comprises the steps of mixing graphite with inorganic salt, sulfate, oxide, inorganic acid, concentrated sulfuric acid, concentrated nitric acid and an oxidizing agent to prepare graphene oxide, and mixing the graphene oxide with organic acid, terpilenol, amine epoxy resin and polyester to prepare the graphene-based conductive ink. The process flow for preparing the graphene-based conductive ink is simple and convenient, the preparation cost is low, and the prepared graphene-based conductive ink is low in conductive agent and metal content, small in pollution to the environment and human bodies, low in toxicity and beneficial to improving the usability of the conductive ink.

Description

technical field [0001] The invention relates to the field of conductive ink preparation, in particular to a graphene-based conductive ink and a preparation method thereof. Background technique [0002] With the development and progress of society and technology, in the 1990s, from traditional silicon-based electronic information technology to modern electronic printing technology, printed conductive ink came into being. Common printed conductive inks include: metal-based conductive inks, conductive polymer-based conductive inks, and carbon-based conductive inks. Traditional electronic devices prepared by photolithography, chemical etching, chemical plating, vacuum deposition, etc. have many defects such as expensive metal consumables, complicated processes, environmental pollution, and poor electrical conductivity. Although the appearance of conductive silver paste is a great progress in printing technology, silver is expensive, which limits its wide application in the prin...
