Dielectric Loss Mechanism in Electromagnetic Wave Absorbing Materials

Ming Qin et al.

Summary: Comprehensive views on dielectric loss mechanisms provide important guidance for understanding the attenuation behavior of materials. Current researches focus more on materials synthesis rather than in-depth mechanism study. Therefore, further research on in-depth mechanisms, emphasis on new dielectric loss mechanisms, and new modulation strategies are needed to achieve simple and effective EM wave attenuation behavior modulation.

Grow defect-rich bamboo-like carbon nanotubes on carbon black for enhanced microwave absorption properties in X band

Yameng Jiao et al.

Summary: In this study, defect-rich bamboo-like carbon nanotubes (CNTs) were grown on carbon black (CB) to establish a developed multilevel conductive network and introduce abundant CB/CNTs nano-interfaces. The defects on CNTs provide moderate conductivity and good impedance matching for effective microwave absorption (MA). Moreover, the high-density defects on CNTs enhance the EMW loss ability by inducing dipole polarization.
