Highly porous, bendable laterally compressed graphene foam (cGF)/acrylonitrile butadiene styrene (ABS) composites are developed by dip coating of ABS on dense cellular-structured, freestanding cGFs. Electrical conductivities of the cGF/ABS composites are enhanced to 6.5 S/cm, higher than that of GF/ABS composites. An electromagnetic interference shielding effectiveness (SE) of 42.4 dB and a specific SE (SSE) of 300.7 dB.cm(3)/g are delivered, shielding 99.99% incident electromagnetic radiations. Compared with isotropic and fragile graphene foam (GF)/ABS composites, the cGF/ABS composites with 75% compression degree of GFs exhibit a distinctive two-layer structure which endows them with strong and bendable performances to a maximum wrapping angle of 50 degrees. Synergistic effects of the unique two layer morphology, the balance between the thicknesses of two layers, the bending direction, and the compressively strong porous structure contributed to the highly bendable properties of 75%-cGF/ABS composites.
