11 Claims

1. A method of producing a composite material that has a thermal conductivity of 0.4 W/mK or more, the method comprising:

forming a porous metal body by sintering a metal structure comprising a metal component;

forming a metal oxide having a protrusion form grown on a surface of the porous metal body by contacting the porous metal body with oxygen, wherein an aspect ratio of the protrusion is in a range of 1 to 8, wherein contacting the porous metal body with oxygen is performed under an oxygen concentration of 1 ppm to 10,000 ppm; and then

applying a polymer component to the porous metal body.
