Multifunctional nanolayered renewable carbon for electromagnetic interference and energy devices

Controlled carbonization of biomass leads to nanolayered graphitic structures with characteristic crystalline sp2 hybridization, conductive properties up to 600 S/m, and electromagnetic interference shielding effectiveness of 47.7 dB at 12 GHz. We investigate functional properties of nanolayered renewable carbon, including conductive and photoluminescent features, leading to a new understanding of structure–property correlation and their …
