Abstract

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 selfhealing within the contact track since they can readily provide CPL to near-by regions. However, once this initial reservoir is completely consumed and depleted, the empty nanowells interfere with long-distance lateral flow process since they act as a reservoir that needs to be filled during the flow.
