Technical Field

[0001] The present invention relates to the technical field of light-transmitting materials, and specifically to a silver, copper, graphene ternary alloy light-transmitting material. Background Art

[0002] The conductive cloth uses a fiber cloth (usually a polyester fiber cloth) as the base material. After pre-treatment, an electroplated metal coating is applied to make it have metal properties and become a conductive fiber cloth. The conductive fiber is ultrasonically cleaned, activated with sulfuric acid, cleaned, and then electroplated in a copper, silver, graphene alloy electroplating solution.
