Abstract

This application relates to a method of manufacturing a metal-polymer composite material having high thermal conductivity and electrical insulating properties. The method may include preparing a powder mixture comprising polymer powder and metal powder, and spark plasma sintering (SPS) the powder mixture to produce a composite material. This application also relates to a metal-polymer composite material having high thermal conductivity and electrical insulating properties, manufactured by the method.

First claim

What is claimed is:

1 . A method of manufacturing a metal-polymer composite material having high thermal conductivity and electrical insulating properties, the method comprising:
preparing a powder mixture comprising polymer powder and metal powder; and spark plasma sintering (SPS) the powder mixture to produce a composite material.

2 . The method according to claim 1 , wherein the polymer comprises:
(i) a thermosetting resin selected from phenol resins, epoxy resins, and polyimide resins, or (ii) a thermoplastic resin selected from olefinic resins, acrylic resins, vinylic resins, styrenic resins, fluoric resins, and fibrin resins.

3 . The method according to claim 1 , wherein the polymer comprises a polyesteric resin.

4 . The method according to claim 3 , wherein the polyesteric resin comprises polyarylate (PAR).

5 . The method according to claim 1 , wherein the metal comprises one or more metals, or an alloy thereof,
and wherein the one or more metals or the alloy are selected from a group including Al, Cu, Ti, Mg, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Zn, Ga, Rb, Sr, Y, Zr, Mo, Ru, Rh, Pd, Ag, Cd, In, Sn, Cs, Ba, La, Ce, Nd, Sm, Eu, Gd, Tb, W, Cd, Sn, Hf, Ir, Pt, and Pb.

6 . The method according to claim 1 , wherein the metal comprises Al, Mg, or Al—Mg alloy.

7 . The method according to claim 1 , wherein the spark plasma sintering (SPS) is performed at a temperature of 150° C. to 450° C. under a pressure of 5 MPa to 100 MPa for 1 minute to 10 minutes.

8 . A metal-polymer composite material manufactured according to the method of claim 1 .

9 . The metal-polymer composite material according to claim 8 , wherein the metal-polymer composite material has a composition of 1% to 99% by volume of metal and 1% to 99% by volume of polymer.

10 . The metal-polymer composite material according to claim 8 , wherein the metal-polymer composite material comprises a functionally graded material (FGM) having a sheet shape of a structure in which two or more layers having different volume ratios of polymer and metal are stacked.
