Electromagnetic interference (EMI) occurs when electronic devices are subject to electromagnetic radiation from unwanted sources at the same frequency ranges that these devices operate. Metals typically serve as excellent EMI shielding agents, but their heavy weight, high cost and susceptibility to
The electromagnetic shielding properties of epoxy resin composites containing short carbon ΓΏbers coated with a layer of non-conducting polyaniline base have been studied. Below the percolation threshold the composites show a high AC conductivity at high frequencies (10 -1300 MHz) and low DC conducti
