Title:
ELECTROMAGNETIC WAVE-SHIELDING MATERIAL HAVING BROADBAND REFLECTION AND ABSORPTION AND FABRICATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/128106
Kind Code:
A1
Abstract:
The present invention relates to an electromagnetic wave-shielding material and a fabricating method therefor, wherein the electromagnetic wave-shielding material is a shielding material that comprises a metal composite including silver (Ag) and a metal ferrite and simultaneously allows for reflection and absorption of electromagnetic waves, the metal composite having a core-shell structure in which silver surrounds the outer surfaces of metal ferrite particles and ranging in particle diameter from 200 to 500 nm. According to the electromagnetic wave-shielding material and the fabricating method therefor, metal composite nano-powder in a core-shell structure that has the form of simultaneously enabling reflection and absorption of electromagnetic waves can be fabricated, and a material with stability against corrosion of the inner core copper metal of the existing core-shell structure, improved electrical properties, a reduced process cost due to a single coating layer, and improved processability and usability can be provided.
