文摘
- •
Novel 3D CIP@PPy aerogel composites were synthesized.
- •
Dopamine was used as intermediary to connect CIPs with PPy.
- •
Flaky carbonyl iron powder enhance internal multiple reflections.
- •
Two strong absorption peaks are −38.9 and −39.5 dB, the bandwidth is 6.1 GHz.
- •
Interfacial polarization and geometry effect are the crucial mechanisms.
