Abstract

To increase the complex permeability and widen the frequency band of carbon nanotubes (CNTs) are the most essential ways for promoting the microwave-absorbing property of microwave-absorbing coatings on multi-wall CNTs. Therefore, we have investigated the relations between the microwave-absorbing behavior and the complex permeability of CNTs, analyzed the electromagnetic parameters of CNTs/paraffin composites of different concentrations under different frequencies, and figured out the external conditions to obtain the optimum wave-absorbing behavior, which is particularly helpful for the further development of new material.
