Layers of adsorbed vapor molecules have profound impacts on adhesion and friction. This article reviews fundamental aspects of alcohol and water adsorption effects on adhesion and friction. Capillary force, a component of adhesion force which arises from the liquid meniscus that forms between contacting surfaces, shows a strong vapor partial pressure dependence that is not explained by theory which...
Surface texturing of silicon substrates with nanowells can change the lubricious performance of cationic polymer lubricant (CPL), a bound-and-mobile lubricant consisting of a polydimethylsiloxane (PDMS) backbone with covalently bonded quaternary ammonium iodide cations. The filled nanowell reservoirs enhance self-healing within the contact track since they can readily provide CPL to near-by regions...
