Title:
ELECTROMAGNETIC WAVE SHIELDING SHEET HAVING FLEXIBILITY AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/169246
Kind Code:
A1
Abstract:
Disclosed are an electromagnetic wave shielding sheet, which can shield electromagnetic waves that may exert a harmful influence over the human body or cause malfunctions of other electronic devices, and a method for manufacturing the same. To this end, provided is an electromagnetic wave shielding sheet comprising: a metal sheet containing Sendust (Fe-Si-Al alloy) flakes; and a conductive sheet disposed on the lower surface of the metal sheet. The present invention can provide an average shielding rate of 70 to 80 dB or more in the frequency band from 300 MHz to 1.5 GHz, and even when the shielding sheet has a small thickness of 100 μm or less, can effectively shield electromagnetic waves, and thus reduce the specific absorption rate (SAR) thereof by the human body. Further, the electromagnetic wave shielding sheet of the present invention can be applied to not only a flat surface but also a curved surface where electromagnetic wave shielding is required.
