| description | The invention discloses a preparation method for preparing a high-strength and high-conductivity copper/CNTs composite material from foamy copper, and belongs to the technical field of metal materials. The method comprises the steps that CNTs are subjected to ultrasonic dispersion in a solvent, foamy copper is hung in the solution, the CNTs are deposited in the foamy copper through electro-deposition, the deposited foamy copper is put into a vacuum drying oven to be internally dried, then the foamy copper is put into a mold to be subjected to cold pressing, then heating and pressurizing are gradually conducted, finally, the pressure is maintained for a certain time, and a sheet-shaped blank is formed; and the blank is subjected to annealing treatment, U-shaped folding continues to repeat the tests, the high-strength and high-conductivity copper/CNTs composite material is obtained after multiple times of folding and hot pressing, and then the high-strength and high-conductivity copper/CNTs composite material i |
