摘要:
Disclosed is an electromagnetic shielding material with enhanced shielding effectiveness and mechanical property by employing a carbon nanotube and a metal as an electrical conductor. The electromagnetic shielding material includes a polymer resin for a matrix and two conductive fillers having a carbon nanotube and a metal, wherein a volume percent of the carbon nanotube ranges about 0.2% to about 10% and a volume percent of the metal powder ranges about 7.0% to about 30% so that the total volume percent of the conductive filler is in a range of about 7.2% to about 40%.
