摘要：
Beta-manganese dioxide (beta-MnO2) nanorods have been fabricated on a large scale by a simple hydrothermal process in a wild condition. Several characterizations such as XRD, SEM, TEM and FESEM have been employed. The wave absorption properties of beta-MnO2/PVDF nanocomposites have been investigated. The results indicated that the beta-MnO2/PVDF nanocomposites exhibit enhanced wave absorption properties. The minimum reflection loss of the beta-MnO2/PVDFnanocomposite reaches -30.1 dB (>99.9% attenuation) at 8.16 GHz with a filler loading of 40 wt.%, and the frequency bandwidth less than -10 dB is from 7.12 to 9.20 GHz. The main microwave absorbing mechanism has been also discussed. (C) 2014 Published by Elsevier B.V.
