In-situ preparation and characterization of pyrrole and tert-butyl 1-pyrrole-carboxylate on barium titanate/poly(acrylonitrile-co-methylacrylate) nanoparticles

Uniform particle size distributions of the nanocomposites were obtained. The size of the nanocomposites decreased with the addition of PPy and TBPy. The spectroscopic characterizations during the formation of (BaTiO3-[P(AN-co-MA)]-PPy) and (BaTiO3-[P(AN-co-MA)]-TBPy) nanocomposites were studied using Fourier transform infrared (FTIR-ATR) spectroscopy, ultraviolet-visible (Uv-Vis) spectrophotometry, and X-ray diffraction(XRD) spectroscopy. Analyses demonstrated that there is a strong interaction between the [P(AN-co-MA)]-PPy and BaTiO3 and also [P(AN-co-MA)]-TBPy and the BaTiO3. The morphological characterizations of the nanocomposites were examined by scanning electron microscopy and transmission electron microscopy. Efficient coverage was observed for BaTiO3 nanoparticles with polymer shell.
