Abstract

A flexible transparent conductive film coating material of doped graphene and white graphene oriented to a liquid coating process, comprising a corona-treated PET or composite substrate layer, and a conductive paint coated on the surface of the PET or composite substrate layer layer, the conductive coating layer includes the following raw materials in weight percentage: 20-50% isopropanol, 20-50% n-butanol, 10-20% ethylene glycol monoethyl ether, 1-5% acetyl tributyl citrate, Adhesive 5-10%, Span 851-5%, ethyl cellulose 0.8-5%, 20-30 nanometer silver powder 4-10%, 100-400 nanometer silver powder 15-20%, graphene homogeneous solution 0.5-5 %, white graphene homogeneous solution 0.5-5%. The conductive film material has the characteristics of stable conductivity of the film-forming surface, low resistivity, high light transmittance, and strong adhesion. At the same time, the film material makes full use of the special properties of white graphene and graphene materials to achieve high performance after film formation. Transparent, conductive, heat dissipation, wear-resistant and other multiple effects.

Description

technical field [0001] The invention relates to the field of flexible transparent conductive films, and provides a flexible transparent conductive film coating material doped with graphene and white graphene that can be used in a liquid coating process. Background technique [0002] At present, the rare metal oxide ITO (indium tin oxide) prepared by vacuum spraying method is almost monopolized in the transparent conductive film market. ITO has the following disadvantages: [0003] 1. The price of rare metals rose rapidly. Due to the rapid development of flat-panel display products and thin-film solar cell industries, the demand for ITO is increasing day by day. Indium, the main element of ITO, is a rare metal with few earth reserves. In the past few years, the price of indium has risen rapidly, and the proven reserves will be used up in the next 10 years. [0004] 2. The investment in the production process is huge and the process is wasteful. Traditional ITO is produce...
