Abstract

The invention relates to the technical field of coating materials, and provides a carbon nanotube ultra-black coating and a preparation method thereof. The preparation method of the carbon nanotube ultra-black coating provided by the invention comprises the following steps: dispersing carbon black in a first dispersion liquid containing a first dispersing agent, an organic auxiliary agent and deionized water to obtain a first mixed system, and mechanically grinding the first mixed system to obtain a carbon black dispersion liquid, wherein the first dispersing agent is aqueous dispersion resin,preparing a second dispersion liquid mixed with a second dispersant and deionized water, dispersing carbon nanotubes in the second dispersion liquid to obtain a second mixed system, grinding the second mixed system, adding deionized water for dilution to obtain a carbon nanotube dispersion liquid, and carrying out mixing treatment on the carbon black dispersion liquid and the carbon nanotube dispersion liquid to obtain the ultra-black coating. Compared with an ultra-black coating singly taking carbon black as a pigment, the reflectivity of the carbon nanotube ultra-black coating provided by the invention is reduced.

Description

technical field

[0001] The application belongs to the technical field of coating materials, in particular to a carbon nanotube ultra-black coating and a preparation method thereof. Background technique

[0002] Ultra-black materials, also called "invisible" materials, are a newly emerging "blackest" material. The ultra-black material only reflects 0.035% of the light, reaching a level that cannot be distinguished by the naked eye. It is as black as a black hole. This "super black" coating material is named "Vantablack". The emergence of ultra-black materials marks a major breakthrough in practical nanotechnology for optical instruments. In practical use, it can improve the sensitivity of optical instruments for use in astronomical cameras, telescopes, and infrared scanning systems. Its ability to reduce astigmatism will improve the "vision" of astronomical telescopes when viewing the faintest stars, and can be used for calibration. The camera for the oldest matter in the u...
