A lightweight graphene foam composite with a density of 0.06 g/cm3 is developed. It shows a EMI shielding effectiveness of 30 dB and specific shielding effectiveness of 500 dB·cm3/g, which surpasses the best values of metals and other carbon‐based composites. In addition, the excellent flexibility o...
