Vertical carbon nanotubes arrays with controlled morphology on silicon carbide fibers for electromagnetic wave absorption

نویسندگان

چکیده

Silicon carbide fiber-Carbon nanotubes arrays (SiCf-CNTs) hybrids with controllable morphologies were successfully synthesized by a floating catalyst chemical vapor deposition method (CVD). As the reaction duration prolonged from 2 min to 15 min, length of CNTs was elongated ?m 50 ?m, and moreover content in increased 1.5 wt% 3.7 wt%. By filling this chopped SiCf-CNTs (20 wt%) into paraffin, composite 3 mm thickness presented minimum reflection loss (RLmin = ?56.2 dB) maximum effective absorption wideband (EAB, RL ? ?10 4.3 GHz (8.5–12.8 GHz). The dielectric performance hybrid optimized CNT's growth density has high potential application electromagnetic wave absorption.

Electromagnetic Wave Absorbing Properties of Amorphous Carbon Nanotubes

Amorphous carbon nanotubes (ACNTs) with diameters in the range of 7-50 nm were used as absorber materials for electromagnetic waves. The electromagnetic wave absorbing composite films were prepared by a dip-coating method using a uniform mixture of rare earth lanthanum nitrate doped ACNTs and polyvinyl chloride (PVC). The microstructures of ACNTs and ACNT/PVC composites were characterized using...

Vertical Silicon Nanowire Arrays for Gas Sensing

The goal of this research was to fabricate and characterize vertically aligned silicon nanowire gas sensors. Silicon nanowires are very attractive for gas sensing applications and vertically aligned silicon nanowires are preferred over horizontal nanowires for gas sensing due to the high density of nanowire arrays and the increased nanowire surface area per substrate area. However, the developm...
