Title:
MILLIMETER WAVE-ABSORBING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/040007
Kind Code:
A1
Abstract:
Provided are a millimeter wave-absorbing structure, a method for producing the same, a millimeter wave absorption method, and a method for suppressing the reflection or scattering of millimeter waves. The millimeter wave-absorbing structure comprises a metal member (A) and a coating film (B) which is formed on the surface of the metal member (A) and is integrated with the metal member (A). The coating film (B) comprises a binder and a carbon particle body having a specific surface area of 30 m2/g or greater. The carbon particle body content is within a range of 1 to 100 parts by mass with respect to 100 parts by mass of the binder. The specific gravity of the coating film (B) is within a range of 1.1 to 2.5 g/cm3 and the film thickness of the coating film is within a range of 100 to 400 µm.
