Preparation, characterization, and property of polyaniline/Prussian blue micro-composites in a low-temperature hydrothermal process

Polyaniline/Prussian blue micro-composites have been synthesized by a low-temperature hydrothermal process. Prussian blue is obtained using the single iron-source precursor K3[Fe(CN)6] in acidic aqueous solution. The composite was characterized by field-emission scanning electron microscopy (FE-SEM), Fourier transmission infrared spectroscopy (FT-IR), and X-ray diffractometer (XRD). The magnetic behavior of polyaniline/Prussian blue composites and the effect of the concentration of K3[Fe(CN)6] on the morphology of polyaniline/Prussian blue micro-composites have been investigated.
