Title:
METHOD FOR PREPARING BRIGHT HIGH-CONDUCTIVITY GRAPHENE/COPPER COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/253114
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of signal transmission, and particularly relates to a method for preparing a bright high-conductivity graphene/copper composite material. In view of the technical problem of bright high-conductivity graphene/copper composite materials being difficult to prepare, provided are a green and environmentally friendly cost-saving graphene/copper deposition solution with a rational ratio and a controllable plating thickness, and an electrodeposition method for preparing a bright high-conductivity graphene/copper composite material having high bonding strength to a substrate and having a smooth surface. First, a graphene/copper deposition solution A containing gelatin and sodium lauryl sulfate as additives is prepared; and then, a pure copper deposition solution B containing polyacrylamide and thiourea as additives is prepared. Deposition is performed by means of alternately depositing the deposition solutions, so as to obtain a bright high-conductivity graphene/copper composite material. The composite material prepared in the present invention has relatively high conductivity while having a smooth and bright surface; in addition, the plating layer has a uniform thickness, the bonding strength to a substrate is high, and the composite material is less prone to being peeled off and detaching.
