Facile synthesis and electromagnetic wave absorption properties of silver coated porous carbon composite materials

Biomass porous carbon (PC) has become a novel microwave absorbing material because of its ultralow density, high dielectric loss capability and friendly to environment. In this study, we prepare Ag/PC composite materials by a simple hydrothermal method from 120 °C to 160 °C. By changing the reaction temperature, the electromagnetic parameters are adjusted and the absorption performance is optimized. XRD results prove the successful preparation...
