Microwave absorption enhancement by adjusting reactant ratios and filler contents based on 1D K-MnO 2 @PDA and poly(vinylidene fluoride) matrix

One-dimensional K-MnO nanorods were prepared by a wet chemical process. Dopamine hydrochloride (PDA) layers with various thicknesses were coated and finally, the composites were filled in a poly(vinylidene fluoride) (PVDF) matrix using the hot-molding procedure. The complex permittivity and permeabi...

Description
Summary:One-dimensional K-MnO nanorods were prepared by a wet chemical process. Dopamine hydrochloride (PDA) layers with various thicknesses were coated and finally, the composites were filled in a poly(vinylidene fluoride) (PVDF) matrix using the hot-molding procedure. The complex permittivity and permeability of the K-MnO @PDA/PVDF composites could be adjusted by reactant amount ratios and filler contents. The minimum reflection loss could reach -49.4 dB and an effective absorption bandwidth (
