MICROTRIBOLOGICAL PROPERTY OF VERTICALLY ALIGNED CARBON NANOTUBE FILM

carbon-nanotube (VACNT) films have been studied [1]. Adhesion forces were obtained by measuring force-displacement curves. Friction experiments were conducted in reciprocating sliding configurations. Effects of tip radius, applied force, scan speed, and relative humidity were investigated. A model of the friction of VACNT film is discussed on the basis of in-situ tribological experiments inside a scanning electron microscope (SEM). A VACNT film was synthesized by microwave plasma enhanced chemical vapor deposition (CVD) on silicon oxide film. Details of the synthesis method and the characterization of VACNT film were described elsewhere [2]. SEM observations revealed that the thickness of the VACNT film was approximately 6 mm
