Our recent achievements in design, processing and studies of physical properties of polymer-nanostructured carbon composites (PNCC) as prospective strain sensor and gas sensor materials are presented. Mechanical, electrical and gas sorption properties have been investigated. Electrically conductive atomic force microscopy (EC AFM), positron annihilation life-time spectroscopy (PALS) and broadband (100 Hz - 2.5 THz) dielectric spectroscopy have been used to investigate the causes of gigantic sensing effects in PNCC. As a result, multifunctional polymer-nanostructured carbon composites exhibiting simultaneously excellent strain sensor and gas sensor properties have been obtained and the existing models of sensing effects improved.
