Synthesis,Characterization, and Optical Properties of Poly(o-methoxyaniline)/BaFe12O19 Composite via an In Situ Polymerization Pathway

Poly(o-methoxyaniline)(POMA)/BaFe₁₂O₁₉ composite was synthesized via a facile in situ polymerization approach for the first time. The structures of the products were characterized by X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) spectra, which indicated the existence of BaFe₁₂O₁₉ particles in the composite. The morphology of the as-prepared samples was observed by using field-emission scanning electron microscopy (FESEM), which revealed that the POMA/BaFe₁₂O₁₉ composite appeared in the form of a general pseudo-sphere-like shape and consisted of numerous highly aggregated globules with rough surfaces. The optical properties of the POMA/BaFe₁₂O₁₉ composite were further investigated by UV-vis spectra. The decrease of band gap for the POMA/BaFe₁₂O₁₉ composite revealed that electronic structure of POMA was affected by BaFe₁₂O₁₉ particles.
