Abstract

Highly flexible carbon ink-loaded polyester fabric/epoxy composites with outstanding mechanical durability and absorption-dominant EMI-shielding characteristics are fabricated.The fracture toughness is ~ 38.5 MPa m^1/2 and electrical conductivity is maintained after 1000 bending cycles.A superior electromagnetic interference SE/t of ~ 66.8 dB mm^–1 was observed in the X-band frequency with over 0.7 absorption coefficient, related to the hierarchical structures composed of macro-scaled voids from the polyester nonwoven fabric skeleton and nano-scaled networks from SWCNTs/rGO.
