Flexible polymer composites with enhanced wave absorption properties based on beta-manganese dioxide nanorods and PVDF

The minimum reflection loss of the β-MnO2/PVDF nanocomposite 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.
