Facile Synthesis and Microwave-Absorption Properties of Organic-Inorganic CoFe₂O₄/Polyaniline Nanocomposites with Embedded Structure.

Organic-inorganic CoFe₂O₄/polyaniline (CoFe₂O₄/PA) nanocomposites with embedded structures were synthesized by combining the sol-gel auto-combustion process and oxidative polymerization. The phases and morphologies of the prepared samples were identified. The pure CoFe₂O₄ samples exhibited inferior microwave-absorption properties in a frequency range of 2-18 GHz.
