| Popis: | In this study, barium titanate BaTiO 3 –poly(acrylonitrile-co-methylacrylate) [P(ANco-MA)]–polypyrrole (PPy) (BaTiO 3 –[P(AN-co-MA)]–PPy) and BaTiO 3 –[P(AN-co-MA)]–poly(tert-butyl 1-pyrrole-carboxylate) (TBPy) (BaTiO 3 –[P(AN-co-MA)]–TBPy) nanocomposites were synthesized separately by in-situ emulsion polymerization in the presence of surfactant dopant dodecyl benzene sulfonic acid (DBSA). Particle size, yield, crystallinity, chemical structure and morphology were fully characterized and systematically studied. 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 (BaTiO 3 –[P(AN-co-MA)]–PPy) and (BaTiO 3 –[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 BaTiO 3 and also [P(AN-co-MA)]–TBPy and the BaTiO 3 . The morphological characterizations of the nanocomposites were examined by scanning electron microscopy and transmission electron microscopy. Efficient coverage was observed for BaTiO 3 nanoparticles with polymer shell. |
