摘要: The films of polypyrrole-tin oxide (PPy-SnO 2 ) nanocomposites were synthesized by chemical oxidative polymerization technique. These irradiated with 90-MeV O 7+ ions at the fluences 5 x 10 , 1 × 11 and 12 ions/ cm . X-ray diffraction studies show that microstrain domain crystallite size SnO nanoparticles in PPy matrix increase ion fluence, resulting highly ordered PPy-SnO nanocomposites. TGA analysis shows inhibit degradation PPy, thereby enhancing thermal stability DC electrical conductivity is found to fluence conduction mechanism follows a one dimensional variable-range hopping model. AC also increases obeys correlated barrier-hopping I-V characteristics exhibit Schottky barrier formation PPy/SnO interface. photoluminescence intensity nanocomposite which can be attributed detrapping charge carriers owing enormous energy transfer during swift, heavy-ion irradiation.
