▎ 摘　　要

NOVELTY - A polypyrrole-based wave-absorbing material has an impedance matching layer, a loss layer and a reflection layer which are provided in top-to-down arrangement. The impedance matching layer is formed by dispersing 2-5 wt.% graphene/iron oxide powder into polypyrrole. The loss layer is formed by dispersing the hydroxy iron powder into neoprene. The reflective layer is formed by dispersing 5-20 wt.% quartz/carbon black composite material into chloroprene rubber. USE - Polypyrrole-based wave-absorbing material (claimed). ADVANTAGE - The polypyrrole-based wave-absorbing material has maximum absorption range of more than 42.3dB, and has excellent performance.
