Laterally compressed graphene foam/acrylonitrile butadiene styrene composites for electromagnetic interference shielding

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·cm3/g are delivered,...
