Abstract

A heat dissipation material includes a plurality of linearly-structured objects of carbon atoms configured to include a first terminal part and a second terminal part; a first diamond-like carbon layer configured to cover the first terminal part of each of the plurality of linearly-structured objects; and a filler layer configured to be permeated between the plurality of linearly-structured objects.

Claims (16)

1. An electronic device comprising:

a heating element;

a heat dissipation element; and

a heat dissipation material configured to be placed between the heating element and the heat dissipation element, and to include

a plurality of linearly-structured objects of carbon atoms including a first terminal part and a second terminal part,

a first diamond-like carbon layer configured to cover the first terminal part of each of the plurality of linearly-structured objects,

a coating film covering a side surface for the first diamond-like carbon layer and the plurality of linearly-structured objects, and

a filler layer configured to be permeated between the plurality of linearly-structured objects.

2. The electronic device as claimed in claim 1 , wherein the first terminal parts of the plurality of linearly-structured objects are connected with each other by the first diamond-like carbon layers.

3. The electronic device as claimed in claim 1 , further comprising:

a second diamond-like carbon layer configured to cover the second terminal part of each of the plurality of linearly-structured objects.

4. The electronic device as claimed in claim 3 , wherein the second terminal parts of the plurality of linearly-structured objects are connected with each other by the second diamond-like carbon layers.

5. The electronic device as claimed in claim 1 , wherein the first terminal part of each of the plurality of linearly-structured objects covered by the first diamond-like carbon layer is placed at a side close to the heating element.

6. The electronic device as claimed in claim 1 , wherein

the first diamond-like carbon layer covers, for each of the plurality of linearly-structured objects, the first terminal part and a portion being adjacent to the first terminal part; and

the coating film covers a surface of the first diamond-like carbon layer, and a side surface of each of the plurality of linearly-structured objects, which is not covered by the first diamond-like carbon layer.
