Electromagnetic Characteristics and Microwave Absorption Properties of CNT Composite
The microwave permittivity and permeability of Carbon Nanotubes (CNTs)/paraffin and CNTs-Co(C)/paraffin were measured respectively and their differences were discussed in detail. Furthermore, the reflection losses for double-layer CNTs (CNTs-Co(C))/epoxy coatings, with the thickness ranged from 1.6-2 mm, were practically tested through Arc Method in 2.6-18 GHz frequence range. The results indicated that the reflection loss peak shifted towards low frequency and the peak value decreased with the coating thickening and possible mechanisms for the phenomena were given.
