New Tribology Findings Reported from University of Lodz (Stability and tribological investigations of 1H, 1H, 2H, 2H-perfluoroalkyltrichlorosilane on titania surface)

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Tribology are presented in a new report. According to news reporting originating in Lodz, Poland, by VerticalNews journalists, research stated, "Tribological and stability properties of fluoroalkylsilane film, obtained from the gas-phase deposition method coated on the titania, are presented. In order to correlate the surface structure with the tribological and stability characteristics, various surface analysis techniques, such as X-ray photoelectron spectroscopy (XPS), ellipsometry, atomic force microscopy (AFM), microtribometry and contact angle measurements, were used."

The news reporters obtained a quote from the research from the University of Lodz, "The stability of fluoroalkylsilane was investigated in tris- and phosphate-buffered saline at 37 degrees C using XPS and contact angle goniometry. The performed measurements proved that the fluoroalkylsilane film shows long-term (minimum 14 days) physiological stability. The influence of relative humidity on the adhesion and friction tests in micro- and nanoscale was also studied. Friction tests performed in the humidity range 10-90% by means of microtribometer and AFM reveal that fluoroalkylsilane is capable to decrease the value of the coefficient of friction by a quarter in comparison with the unmodified surface. The increase of humidity does not change the obtained values of the coefficient of friction and adhesive force for the modified surface."

According to the news reporters, the research concluded: "From wear tests it was also found that the fluoroalkylsilane film on the titania surface could not be easily removed even under a few micro-Newton normal load."
