Abstract
The present application provides a composite material and a method for producing the same. The present application can provide a composite material which comprises a metal foam and a polymer component, and has other excellent physical properties such as impact resistance, processability and insulation properties while having excellent thermal conductivity.
Claims11
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.
