US 11,079,284 B2 · Plane source blackbody

Abstract

The present invention relates to a surface source blackbody. The plane source blackbody comprises a panel, and a plurality of carbon nanotubes. The panel comprises a first surface and a second surface opposite to the first surface. A carbon nanotube array is located on the first surface of the panel. The carbon nanotube array comprises a plurality of carbon nanotubes. The plurality of carbon nanotubes are substantially perpendicular to the first surface of the panel. The carbon nanotube array has a high emissivity, so the plane source blackbody using the carbon nanotube array as a surface material has a high effective emissivity.

Dependent claims

A plane source blackbody comprising:

a panel comprising a first surface and a second surface opposite to the first surface;
a carbon nanotube array on the first surface of the panel, wherein the carbon nanotube array comprises a plurality of carbon nanotubes, the plurality of carbon nanotubes are substantially perpendicular to the first surface of the panel, and the carbon nanotube array has a high emissivity, so the plane source blackbody using the carbon nanotube array as a surface material has a high effective emissivity;
and the first surface of the panel is partially covered by the carbon nanotube array, the first surface of the panel which is not covered by the carbon nanotube array is covered by a black coating.

Dependencies are inferred from the claim text.
