Abstract

It is crucial to obtain infrared emission coating materials with emissivity close to one unit for remote sensing temperature measurement, earth climate monitoring and other fields. In order to obtain large-area uniform high emissivity coating, multi-layer spraying and multi-walled carbon nanotubes doping were used to enhance the emissivity of commercial black paint NVC811-21 from 8μm to 14μm. Compared with the coating directly sprayed with NVC811-21, the emissivity of the coating in the normal band from 8μm to 14μm in the atmosphere can be increased from 0.965 to 0.978. In addition, from the spectral emissivity of the coating in this band, the doping of carbon nanotubes can improve the emissivity near 10μm of the coating. For NVC811-21, this improves the uniformity of the spectral emissivity of the coating material. Due to the application of NVC811-21 in the actual service of the on-orbit blackbody, this paper's preparation method may help improve the emissivity of the on-orbit blackbody and the measurement accuracy of satellite remote sensors.
