Controllable synthesis of uniform ZnO nanorods and their enhanced dielectric and absorption properties

The PVDF/ZnO composites were prepared by a simple hot-press method. The dielectric behavior of the composites was improved at a lower percolation threshold. For the composites with a filler content of 10 wt%, the reflection loss appears as two peaks that can reach −15.90 dB at 6.60 GHz and −25.44 dB at 16.48 GHz.
