(A) Schematic for (a) synthesis of RGF, (b) preparation of reflection-absorption-integrated shielding compartments, and (c) CNT/RGF/PC composites; (B) (a) Scanning electron micrograph of CNT/RGF/PC composite, (b) and (c) are the higher magnification micrographs of (a), (d) energy dispersive X-ray elemental mapping of Fe and (e, f) transmission electron micrograph of CNT/RGF/PC composite. The inset cartoons show the composite’s observing area; (C) Shielding mechanism of the reflection-absorption-integrated shielding compartment. Adapted with permission from Li et al.
