Abstract

Line tension was measured for microliter-scale and subnanoliter-scale droplets of an ionic liquid on a highly smooth and homogeneous fluoroalkylsilane coating. Values for microliter-scale droplets were two orders larger than those for subnanoliter-scale droplets despite their identical combinations of solid surfaces and liquid. Scale factors related to this measurement and hydrostatic pressure from the liquid play an important role in the discrepancy.
