A CORE-SHELL FORM COMPOSITE POWDER, AND MANUFACTURING METHOD OF THE SAME

摘要

A manufacturing method of a core-shell type silver-carbon composite powder comprises: a step of preparing silver through a pulsed wire evaporation method; a step of placing the silver into a solution where carbon nanofilaments are dispersed; a step of applying magnetic fields to the solution where the silver is dispersed in the carbon nanofilaments, and treating the solution with ultrasonic waves; a step of drying a silver alloy composite treated with the ultrasonic waves; and a step of mechanically alloying the dried silver alloy composite. As such, the present invention improves a coherence between carbon nanotubes and silver particles.
