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 intermolecular interactions at the interface between a monomolecular hydroxyl-terminated perfluoropolyether (PFPE) liquid and an amorphous silicon nitride (SiNx) film were investigated using contact angle goniometry, Fourier transform infrared sp

We have used a quartz crystal microbalance (QCM) to study the solution-phase adsorption of the perfluoropolyether lubricants Fomblin ZDOL and Demnum SA from perfluorohexane and perfluorobutylmethyl ether onto model carbon-coated hard-disk surfaces. T

Methods to chemically passivate the surfaces of amorphous-carbon films (a-C) produced by dc magnetron sputtering were studied. The chemical composition of carbon surfaces produced via sputtering are dependent upon the environment to which the carbon

The magnetic recording industry predominantly uses Zdol to lubricate the carbon overcoat of magnetic recording disks. Zdol comprises a perfluoropolyether chain terminated with hydroxyl end groups that are capable of reversibly bonding to the carbon o

Ultrathin fluoropolymer films were deposited by a plasma-enhanced chemical vapor deposition process, from mixtures of hexafluoropropylene (C3F6) and octafluoropropane (C3F8) precursors. Different monomer feed compositions result in different rates of

The high-frequency frictional properties of thin lubricating layers of perfluoropolyethers coated onto the surface of quartz-crystal resonators were probed by measuring the increase in resonance bandwidth when the quartz surface comes into contact wi
