Amorphous carbon-matrix composites with interconnected carbon nano-ribbon networks for electromagnetic interference shielding
Abstract.
Carbon-matrix composites with self-assembly interconnected carbon nano-ribbon networks
were fabricated using natural and inexpensive rice husks by impregnating the rice
husks with transitional metal solutions and sintering. The nano-structure of the composite
was characterized using transmission electron microscopy. The electromagnetic interference
shielding effectiveness of the composite was evaluated in the frequency range of
30 kHz–1.5 GHz. The electrical conductivity was measured as a function of the sintering
temperature. These characteristics were compared with those of carbon-matrix composites
without nano-ribbon networks.
