Microwave absorption enhancement of CIP/PANI composites

The carbonyl iron powder and polyaniline (CIP/PANI) composites have been synthesized by in situ polymerization method and it is found that the doped acid mole ratio has great influence on the properties of the composites. At proper mole ratio of doped acid to aniline, a non-magnetic phase appears due to interaction between the micro-sphere CIP and the PANI polymer, which weakens the magnetic loss and dielectric loss of the composite...
