Abstract: |
The heat interface material includes one base body and carbon nanotubes distributed inside the base body. The base body includes one first surface and one opposite second surface, and the carbon nanotubes extend from the first surface to the second surface and extend beyond at least one surface to bend elastically inside a phase change material layer formed in the surface. The present invention also provides the making process of the heat interface material. Owing to the carbon nanotubes with at least one end elastically bending in the phase change material, the heat interface material has good heat interface contact, low heat resistance and high heat conducting efficiency. |
