基于石墨烯基纸的复合材料已通过将溶液配置的功能化石墨烯纳入环氧基质中制造，并研究了其电磁干扰（EMI）屏蔽研究。该复合材料的渗滤阈值低于0.52卷。在8.2-12.4 GHz（X波段）的频率范围内测试了EMI屏蔽效率，并获得了15 wt％（8.8 vol。％）的负载，获得了21 dB的屏蔽效率，这表明它们可以用作轻巧，有效的EMI屏蔽材料。 （c）2008年由Elsevier Ltd.出版。
Composites based on graphene-based sheets have been fabricated by incorporating solution-processable functionalized graphene into an epoxy matrix, and their electromagnetic interference (EMI) shielding studies were studied. The composites show a low percolation threshold of 0.52 vol.%. EMI shielding effectiveness was tested over a frequency range of 8.2-12.4 GHz (X-band), and 21 dB shielding efficiency was obtained for 15 wt% (8.8 vol.%) loading, indicating that they may be used as lightweight, effective EMI shielding materials.
