Title:
ELECTROMAGNETIC WAVE SHIELDING MEMBER AND ELECTRONIC DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/154196
Kind Code:
A1
Abstract:
The present invention provides an electromagnetic wave shielding member and an electronic device comprising same, the electromagnetic wave shielding member comprising: a first composite layer in which electromagnetic wave absorbing particles and electromagnetic wave reflecting particles are dispersed in a matrix; and a second composite layer which is formed on one surface of the first composite layer and in which electromagnetic wave absorbing particles are dispersed in a matrix, wherein the absorbing particles and the reflecting particles each comprise a core and a shell coating layer covering the core. The electromagnetic wave shielding member of the present invention simultaneously implements reflection and absorption functions of electromagnetic waves, and can thus selectively remove electromagnetic waves of a desired specific frequency band in a situation in which electromagnetic waves of a wide frequency range are mixed.
