Description

technical field [0001] The invention relates to the field of functional coatings, in particular to a graphene conductive coating with a luminescent function and a preparation method thereof. Background technique [0002] General conductive coatings use non-ferrous metals or carbon black as conductive cross-linking substances. Although the conductivity can be made very good, there is no way to achieve transparency and conduction. [0003] Transparent conductive paint, currently the main technology is in the hands of a few developed countries abroad, the price is very expensive, sold in grams, close to tens of yuan per gram. [0004] In order to realize the localization of transparent conductive coatings, make up for the shortcomings of colored conductive coatings covering the background color during use, and further improve the conductivity of conductive coatings, a graphene material and UV glue are used to design a product that can withstand sunlight. It can be quickly soli...
