Synthesis of flowerlike nickel particles and their microwave absorbing properties

Abstract

Two kinds of nickel particles with flower-like structures assembled with a number of nano-flakes were synthesized and the relationship of their morphology and microwave absorbing properties was studied. The electromagnetic parameters of these flower-like Ni were measured with vector network analyzer at 2–18 GHz frequency and the reflection losses (RL) with different sample thicknesses were calculated. The results indicate that the flower-like nickel-wax composites with the sample thickness less than 2 mm show excellent absorbing ability. This result is expected to play a guiding role in the preparation of the highly efficient absorber.
