HIGH PERFORMANCE EMI/FRI SHIELDING POLYMER COMPOSITE HAVING EXCELLENT ELECTROMAGNETIC SHIELDING EFFECT BY SIMULTANEOUSLY INCLUDING A CONDUCTIVE FILTER AND METAL HAVING A LOW MELTING POINT

摘要

PURPOSE: A high performance EMI(electromagnetic interference)/RFI(radio frequency interference) shielding polymer composite is provided to minimize a surface impedance by maximizing network between conductive filters using a metal having a low melting point and to effectively perform EMI/RFI shielding by maximizing inner scattering of electromagnetic wave through the conductive filler.;CONSTITUTION: A high performance EMI/RFI shielding polymer includes a thermosetting polymer resin, a conductive filer which is a polyhedron, and a metal having a low melting point. The content of the metal having the low melting point is 1-10 volume %. The content of the conductive filer is 5-69 volume %. The polymer composite includes a glass fiber filler with an amount of 50 parts by weight or less based on 100.0 parts by weight of the polymer composite.;COPYRIGHT KIPO 2010
