Steric stabilizer-based promotion of uniform polyaniline shell for enhanced electromagnetic wave absorption of carbon nanotube/polyaniline hybrids

Carbon nanotubes (CNTs) are potential electromagnetic (EM) wave absorption (MA) material due to the strong dielectric loss, nevertheless, sole CNTs suffer from limited MA ability because of the interface impedance mismatch of CNTs and the skin effect, which leads to high reflection of EM wave. The impedance mismatch characteristics of CNTs can be effectively improved by incorporation of polyaniline (PANI) with an intermediate conductivity....
