This randomized trial examines how liquid spreads on rough surfaces, highlighting the role of the precursor film in wetting processes.

This research investigates how liquids spread on nanopatterned surfaces, focusing on the formation of a precursor film.
Used advanced nanofabrication techniques to create surfaces with nanopillars of varying heights.
Employed liquid-phase transmission electron microscopy for real-time imaging of the wetting process.
Documented the dynamics of water spreading across the patterned surfaces.
Identified that water forms an ultrathin precursor film before wetting the nanopatterned surface.
Observed that capillary action from nanopillars increases the thickness of the water film.
Captured nanoscale details of the precursor film, revealing its vital role in the wetting process.

Anand et al. (2021) studied this question.
