Abstract

Abstract—Nanocomposites have been synthesized by the destruction of copper electrodes in the plasma of a pulsed high-voltage discharge in the presence of fluoroplast. Nanocomposites include copper-containing nanoparticles distributed in a carbon-fluorocarbon matrix made from chain nanofibrils. Calcining of the specimens has afforded coils from carbon nanoribbons. An identical behavior of magnetic susceptibility M(H) has been determined in initial and calcined specimens, which manifests itself in gradual changes at specific values of magnetic field, which suggests the existence of a Josephson contact environment at room temperature. High-molecular fluorocarbon compounds, which do not correspond to PTFE molecules, have been determined in the products of pyrolysis of initial specimens. A powder specimen consisting of the composite nanoparticles containing PTFE and these compounds has been prepared. It has been demonstrated that high-molecular fluoroorganic compounds, which are not poly(tetrafluoroethylene) molecules, are formed from fluoroplast molecules after exposure to the plasma of pulsed of high-voltage discharge on fluoroplast.
