An Xps and Low-Temperature Nitrogen Adsorption Study of the Structure of Carbon-Fluorocarbon Nanocomposites

详细

The products of mechanosynthesis in the systems “superstoichiometric fluorocarbon nanomaterial CF_1.2–thermally expanded graphite” are studied using X-ray photoelectron spectroscopy and low-temperature nitrogen adsorption to identify texture characteristics. A correlation is revealed between the conductivity of the composites and functional composition of their surface layers. The obtained results are explained by the fact that mechanosynthesis products contain mesoporous carbon-fluorocarbon nanocomposites consisting of micro- and nanoparticles CF_1+x coated by an outer nanolayer sp²-C–sp³-C–F.
