Strategies toward processing high-efficient MWCNTs/AgBr/PTs -co-PQ nanocomposite coupling for X-band stealth application.

There is a pressing desire for the development of ideal microwave absorption materials to tackle the escalating issue of electromagnetic interference (EMI) in electronic gadgets. So, EMI absorption material is an urgent requirement at the present time. Herein, a novel composite, MWCNTs enwrapped with AgBr and Poly(Thiophene- co -Quinoxaline), has been successfully synthesized to study absorption properties in X-bnad frequency range. The primary objective of this study is to increase the microwave absorption performance of composites by regulating their attenuation constant and impedance matching. The improved microwave absorption efficiency of MWCNTs/AgBr/Poly(Thiophene- co -Quinoxaline) has been achieved by using various filler contents. The optimal sample achieves RL mini of −54 dB with EAB of 2.2 GHz. As a result, the developed nanocomposites could be used in the field of microwave absorption.
