Facile Synthesis of Polyindole/Ni Zn FeO ( = 0, 0.5, 1) Nanocomposites and Their Enhanced Microwave Absorption and Shielding Properties.

The present work reports the fabrication of polyindole (PIN)/Ni Zn FeO ( = 0, 0.5, 1) nanocomposites as efficient electromagnetic wave absorbers by a facile in situ emulsion polymerization method for the first time. The samples were characterized through Fourier transform infrared spectroscopy, UV-vis spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, high-resolution transmission electron microscopy, and vibrating sample magnetometry.
