Plasma-assisted doping of pyrolyzed corn husk strengthened by MoS/polyethersulfone for fascinating microwave absorbing/shielding and energy saving properties.

To address the ever-increasing electromagnetic pollution, numerous efforts have been made. In this case, biomass-derived materials as green, affordable, lightweight, capable, and sustainable microwave-absorbing materials have become a research hotspot; meanwhile, transition metal-based microwave absorbers and sulfide structures as polarizable electromagnetic absorbers have intrigued researchers. Alternatively, plasma treatment as a novel strategy has been applied in different fields, and doping strategies are in the spotlight to modify the microwave-absorbing features of materials.
