Title:
RADIATIVE COOLING MULTILAYER FILMS
Document Type and Number:
WIPO Patent Application WO/2023/090702
Kind Code:
A1
Abstract:
Disclosed is a radiative cooling multilayer film having a structure in which a post-processing process is easy while practical radiation cooling performance is achieved. The present invention provides a radiative cooling multilayer film comprising: a first infrared radiation layer including a first polymer in which first dielectric particles are dispersed; a second infrared radiation layer including a second polymer in which second dielectric particles are dispersed; a third infrared radiation layer including a third polymer in which third dielectric particles are dispersed; and a fourth infrared radiation layer including a fourth polymer, wherein the first dielectric particles, the second dielectric particles, and the third dielectric particles are same or different types.
