Résumé
Biomass material has gained significant popularity due to its potential to meet the requirements of green and sustainable development in modern times. It is widely used in various fields, especially for absorbing electromagnetic waves (EMW). In this study, we used luffa sponge carbon (CLS) as a lightweight and porous carbon source. Through a static reaction and heat treatment process, we successfully loaded coral sheet cobalt onto the surface of CLS to create lightweight and efficient luffa sponge carbon/cobalt (CLS/Co) composites for EMW absorption. We controlled the microstructure and electromagnetic properties of the CLS/Co composites by adjusting the pyrolysis temperature. At 700 °C, the CLS/Co composites showed a minimum reflection loss (RL
