Abstract
Official abstract text for this publication.
Disclosed are electrical contact materials and a method for preparing the same. The electrical contact material includes (i) one or more kinds of metals selected from the group consisting of silver (Ag), copper (Cu) and gold (Au), and an alloy of nickel (Ni); and (ii) carbon nano tubes (CNTs) coated with Ag nanoparticles, Ag plated CNTs, or Ag nanowires, or (i) one or more kinds of metals selected from the group consisting of Ag, Cu, Ni and Au; (ii) a metal oxide that is cadmium oxide, indium oxide, tin oxide, zinc oxide or mixture thereof; and (iii) CNTs coated with Ag nanoparticles, Ag plated CNTs, or Ag nanowires. Accordingly, it is possible to reduce the content of high-priced Ag and to obtain excellent electrical and mechanical properties.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrical contact material, comprising: (i) an alloy comprising a mixture of nickel (Ni) and one or more kinds of metals selected from the group consisting of silver (Ag), copper (Cu) and gold (Au); and (ii) carbon nano tubes (CNTs) coated with Ag nanoparticles, wherein a size of each of the Ag nanoparticles is 3 to 5 nm, wherein, based on an entire weight of the alloy, wt % of the metal is 55 to 65 wt % and wt % of the Ni is 35 to 45 wt %, wherein, based on an entire weight of the electrical contact material, wt % of the CNTs is 0.1 to 5 wt %. 2. The electrical contact material of claim 1 , wherein the one or more kinds of metal is the Ag.
