Abstract

In order to obtain a flexible electromagnetic shielding materials with thin thickness and low electromagnetic wave reflection, pyrolytic carbon (PyC) and carbon nanotube (CNT) were in situ formed on the surface of SiC fiber fabrics (SiC_f, with the thickness of 0.34 mm) through chemical vapor deposition and catalytic chemical vapor deposition to form PyC-SiC_f and CNT-SiC_f fabrics, separately. CNT-SiC_f can maintain the flexibility of SiC fiber fabrics because of the high aspect ratio of CNT, but PyC-SiC_f fabrics can not. CNT-SiC_f had much lower electrical conductivity than PyC-SiC_f because of their higher contact electrical resistance. At the same loading, CNT-SiC_f and PyC-SiC_f could obtain higher EMI SE (≥15 dB), but CNT-SiC_f had lower reflection loss (≤6 dB) than PyC-SiC_f (≥8 dB) because CNT-SiC_f had much lower electrical conductivity and larger interface area than PyC-SiC_f.
