摘要

Atomic-molecular engineering is an effective way to accurately tailor themicrostructures and components of materials at the micro-nano scale, whichcan be applied to flexibly manipulate their electromagnetic (EM) response.Herein, graphene microlaminates with multi-layer structure are fabricated byatomic cluster engineering and oxidative molecular layer deposition for thefirst time. The microlaminates enable a tunable EM loss (from 0.93 to 3.94for imaginary permittivity and from 0.17 to 0.25 for imaginary permeability)by changing poly(3,4-ethylenedioxythiophene) cycles, and the attenuationconstant reaches 160. On this basis, multifunctional antennas are conceived,achieving frequency-selective response that enables steady harvest of > 90%of EM energy from signal source, and tactfully recycling waste heat energyand mechanical energy. This study will furnish a new horizon for informationtransmission and artificial intelligence in the future.
