ABSTRACT: Composites based on ultradispersed
polytetrafluoroethylene and intercalated graphite oxide compounds with dodecahydro-closo-dodecaborates
and methods of their fabrication have been developed. The fabricated composites
have been characterized using XRD analysis, and optical microscopy. These
composites are distinguished with completeness of their combustion, since the
combustion products comprise gaseous boron fluorine-containing compounds of
boron, boron trifluoride (BF3), and boron oxyfluoride ((BOF)3). Besides, these
composites are characterized with increased energy capacity as compared to purely
oxygen-containing compounds, since the heat of formation of boron fluorine-containing
compounds is higher than that of boron oxide. Introduction of ultradispersed
polytetrafluoroethylene imparts composites with hydrophobicity, thus improving
their functioning properties.
