摘要: Abstract Electron Spin Resonance investigations on polyurethane – vapor grown carbon nanofiber composites are reported. The research focuses the free radicals generated during processing step and ESR spectrum of conducting electrons delocalized over nanofiber. deactivation due to their interaction with residing was analyzed related enhanced stability these composites. dependence resonance line parameters concentration nanofiller is studied in detail. Experimental data indicates that electrical conductivity uncoupled domains suggests dominated by polarons. percolation also reflected data. interactions between electronic spins, as revealed width nanofibers discussed
