Abstract

CI@Co-P particles are prepared by electroless plating technics. The structure, morphology, and antioxidant properties analyses demonstrate that the the CI particles have been coated with intact spherical-shell Co-P coating, and the Co-P coatings, as the efficient barriers to prevent the further oxidation of the CI particles, can delay the oxidant temperature of CI about 150 °C. In terms of reflection loss (RL), the absorbing frequency band (AFB, the value of RL< -10 dB) and the matching thickness (tm), CI particles also show effective performances after the surface modification of Co-P: minimum RL of -45.0 dB with tm=1.6mm at 9.7 GHz, AFB of 8.2- 12.4GHz. The results indicate that Co-P coated CI particles can significantly improve the antioxidant properties of CI particles with no negative influence for RL of CI and that CI@Co-P particles could be used as an effective microwave absorption material..
