Negative pressures in nanoporous membranes for thin film evaporation

(author unknown)



Rong Xiao, Shalabh C. Maroo, and Evelyn N. Wang

We present a nanoporous membrane-based approach, which decouples the capillary pressure from the viscous resistance, to achieve high driving pressures and efficient liquid delivery for thin film evaporation. By using alumina membranes with ≈150 nm pore diameters, absolute liquid pressures as low a ... [Appl. Phys. Lett. 102, 123103 (2013)] published Wed Mar 27, 2013.
