摘要：

The electromagnetic interference (EMI) shielding of well dispersed single-walled carbon nanotube (SWCNT)/polyurethane composites was studied and the results show that they can be used as effective and lightweight shielding materials. The EMI shielding of the composite shows a reflection-dominant mechanism, while a shift from reflection to absorption was observed with increased SWCNT loading and frequency. This is explained using EMI shielding theory and the intrinsic properties of the components. (c) 2006 Elsevier Ltd. All rights reserved.
