Banana-peel derived activated carbon for microwave absorption at X-band frequency

The rapid advancement in information technology, communication, and electronic devices elevates the need to develop suitable materials for microwave absorption (MA) which should have properties of an ideal absorber. Porous activated carbon from agricultural wastes has piqued interest MA researchers due their distinct such as good specific surface area, high dielectric loss, electrical conductivity, low density. Herein banana peel was prepared by activating precursor with KOH carbonizing at different temperatures. difference porous structure varying carbonization temperature visible FESEM image, validated BET analysis. Banana Peel Activated samples exhibited performance, BP-AC700 displaying a minimum Reflection Loss (RL) −40.62 dB 10.72 GHz & 3.0 mm thickness. In addition, obtained effective bandwidth 3.5 spanned through X band frequency. This exceptional attained sample's conductive loss favourable morphology. study inspires development future facile functional waste-derived absorbers.
