The interfacial properties of perfluoropolyether (PFPE) films having the [(CF2)nO] main chain with n = 1.5, 3 and 4, were systematically compared on carbon surfaces. The monolayer thickness decreases with increasing n, indicating that stiffer chains

The D-4OH adsorbed film structure is investigated as a function of film thickness and of molecular weight via surface energy measurements, terraced flow profiles, and ellipsometric imaging for film dewetting. The D-4OH monolayer thickness on a carbon

Slider-disk contact hysteresis is investigated as a function of the Zdol bonded fraction at constant film thickness. The contact hysteresis is found to increase with the Zdol bonded fraction. AFM force-distance curves also indicate increasing work of

The UV irradiation of Z-Tetraol films on amorphous nitrogenated carbon surfaces was investigated. COF2 evolution, captured in the gas phase, decreased with increasing number of OH end groups in the order: Z > Zdol > Z-Tetraol after UV irradiation. Bo

The thin film properties of some novel branched perfluoropolyether (PFPE) boundary lubricants are investigated as a function of molecular polarity and end-group bonding to the underlying carbon film. The PFPE main chain, comprised of n-perfluoroethyl

In magnetic hard disk drives, it is important to evaluate the replenishment effect of a submonolayer lubricant film under a more severe condition that the head&ndash
disk spacing has to be reduced from the current 0.7 nm to ~0.5 nm. In contrast
