摘要：

A lightweight graphene foam composite with a density of 0.06 g/cm 3 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 of this foam composite gives it a stable EMI shielding performance under repeated bending. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
