Synthesis and Study of the Properties of Porous Carbon-Carbon Nanocomposites with Nitrogen-Containing Carbon Nanofibers

The possibility of synthesizing carbon-carbon nanocomposites with nanofibers embedded in a carbon matrix by two-stage dehydrochlorination (under the action of alkali followed by carbonization) of a carbon-chain chloropolymer has been shown. Chlorinated polyvinyl chloride was used as the initial chloropolymer, and nitrogen-containing carbon nanofibers (N-CNFs) were used as a nanoscale component. The structure of the resulting nanocomposites was examined by electron microscopy and the texture parameters were studied using low-temperature nitrogen adsorption-desorption. The introduction of N-CNFs into the carbon matrix and the activation of the resulting carbon-carbon nanocomposite in an atmosphere of CO2 contributed to the formation of a micro- and mesoporous material with a specific surface area of similar to 1100 m(2)/g. It was shown that the resulting nanocomposites were characterized by high energy capacity and energy efficiency when tested as electrodes of electrochemical supercapacitors.
