Conductometry and Size Characterization of Polypyrrole Nanoparticles Produced by Ball Milling
Popis výsledku v původním jazyce
Polypyrrole (PPy), one of the most extensively investigated conducting polymers, has attracted a great deal of interest because of its good electrical conductivity, environmental stability, and easy synthesis. PPy films were produced by polymerization ofpyrrole and tosylate (TsO-) as dopants in the presence of oxidant FeCl3 and polyethylene glycol ( 8000) at -5°C for 48?h. High energy milling was carried out at 850 rpm in the dry media with the balls of 10?mm. Particles were then characterized by Scanning Electron Microscope and Dynamic Light Scattering techniques for size distribution, and it was found that the size of PPy particles is a decreasing function of time of milling. Electrical conductivity was measured by preparing a homogenous aqueous dispersion of PPy particles and found as exponential decreasing function of time of milling. The changes occurred in PPy after milling was analyzed by Differential Scanning Calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR)
