Abstract
A combined approach to the synthesis of functional nanocomposite materials based on fibroporous polytetrafluoroethylene (PTFE) prepared by the CO2 laser irradiation of the block PTFE sample (fluoroplastic-4) has been developed. Fibroporous materials (FPM) such as cotton and felt were modified by supercritical carbon dioxide treatment to create nano- and micropores in the surface layers of FPM fibers. The gold- and silver-containing fibroporous nanocomposites have been obtained by processing the nano-structured FPM with the organosols of the metal nanoparticles in isopropanol prepared by metal-vapor synthesis. The composition and structure of the metal-containing fluoropolymers have been investigated by X-ray analysis and electron microscopy.
