Title:
PREPARATION METHOD FOR HIGHLY CONDUCTIVE GRAPHENE COPPER/ALUMINIUM COMPOSITE WIRE
Document Type and Number:
WIPO Patent Application WO/2021/027607
Kind Code:
A1
Abstract:
A preparation method for a highly conductive graphene copper/aluminium composite wire. A deposition solution for said wire consists of, by mass percentage: 20 wt% of CuSO4, 0.005 wt% to 0.020 wt% of benzylideneacetone, 2 wt% to 5 wt% of NaCl, 0.08 wt% to 0.05 wt% of graphene, 0.003 wt% to 0.016 wt% of N,N-dimethylformamide, and the balance of deionized water. The preparation method for said wire comprises electrodeposition, drawing and annealing. The wire obtained has excellent conductivity and tensile strength, being capable of effectively improving the power transmission efficiency and reducing the power consumption. The formulation of the electrodeposition solution and the preparation method above ensure the comprehensive performance and microscopic structure of a composite material by controlling process parameters, and a novel practical wire having a simple preparation method and high transmission efficiency is obtained.
