Abstract

Electromagnetic interference (EMI) shielding coatings based on carbon nanotube (CNT) has been prepared and evaluated. The electromagnetic shielding effectiveness is measured using planar material fixture method from 10MHz to 3 GHz and with free space method in the range of 3 GHz to 18 GHz. The results show that carbon nanotube based coating is effective in providing EMI shielding in broad frequency range from 10 MHz to 18 GHz. CNT based coating showed good shielding effectiveness (25-30dB) and absorption performances (60%-90%) in wide frequency range.
