CoNi@SiO2 @TiO2 and CoNi@Air@TiO2 Microspheres with Strong Wideband Microwave Absorption.
The synthesis of CoNi@SiO2 @TiO2 core shell and CoNi@Air@TiO2 yolk shell microspheres is reported for the first time. Owing to the magnetic dielectric synergistic effect, the obtained CoNi@SiO2 @TiO2 microspheres exhibit outstanding microwave absorption performance with a maximum reflection loss of 58.2 dB and wide bandwidth of 8.1 GHz (8.0 16.1 GHz, 10 dB)
