Title:
METHOD FOR PREPARING RADIATIVE COOLING METAMATERIAL BY POWDER COATING
Document Type and Number:
WIPO Patent Application WO/2023/132560
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a metamaterial in the form of a film having high visible light transmittance and excellent radiative cooling characteristics even with a small thickness, by powder coating. In the present invention, a metamaterial in the form of a highly transparent film can be prepared by powder coating of aerogel particles, an optical modulator, and a base resin. The metamaterial formed according to the present invention can exhibit excellent visible light transmittance and heat dissipation characteristics and, since a powder coating process is used, a metamaterial coating can be formed regardless of the shape of an object and the coating can be thin and uniform.
