More Information
Summary:The present invention relates to an electromagnetic wave shielding film containing metal ferrite and a method for manufacturing the same, and more specifically, to metal ferrite particles for shielding an electromagnetic wave applicable to frequencies of 30 MHz to 20 GHz by comprising a highly conductive material having an electromagnetic interference (EMI) effect and a magnet material having electromagnetic susceptibility (EMS), and a method for manufacturing the same. 본 발명은 금속 페라이트를 포함하는 전자기파 차폐 필름 및 이의 제조방법에 관한 것으로, 보다 구체적으로 전자기파 차폐(Electro Magnetic Interference, EMI) 효과를 갖는 고전도성 소재 및 전자기 내성(Electro Magnetic Susceptibility, EMS)을 갖는 자성소재를 포함하여 30 MHz 내지 20 GHz 주파수까지 적용 가능한 전자기파 차폐를 위한 금속 페라이트 입자 및 이의 제조방법에 관한 것이다.
