Abstract:Conjugated polymer composites with different dielectric properties can be widely used in electronics industry, sensors, batteries, smart windows and to reduce electromagnetic interference. In this study monodispersed polypyrrole composite nanospheres were synthesized by the presence of surfactants. Pyrrole(Py) was adsorbed onto -copolymer particle core dispersions. Surfactants were introducing the electronegative sites onto the surfaces of particles, which the pyrrole cationic ions can be adsorbed via static forces to surfaces, and Py can be oxidatively polymerized to encapsulate the matrix. In-situ oxidative polymerization of monomer of conjugated polymer in solution favored the formation of the well defined nanoparticles of nanocomposites with a size of ~80-100 nm diameter. Nanofibers of composites were obtained by electrospinning were characterizedby using NMR, FTIR-ATR, UV-Visible, and Differential Scanning Calorimeter (DSC). The relationship between conjugated polymer content, viscosity and fiber diameter were examined and increase in PPy content caused decrase in nanofiber diameter, determined by scanning electron microscopy (SEM) and atomic force spectroscopy (AFM) and increase in AC conductivities were followed by Electrochemical Impedance Study.
