Capillary Rise and Flow of Complex Liquids in Nanopores — •Simon Grüner and Patrick Huber — Saarland University

We present measurements on the capillary rise (spontaneous imbibition) and pressure driven flow (forced imbibition) of liquids into silica monoliths (namely porous Vycor) permeated by tortuous pores with radii of 5nm. The flow properties are studied as a function of the complexity of the building blocks of the liquids (water, n-alkanes and liquid crystals), as a function of shear rate and as a function of temperature in the case of the liquid crystal. This work has been supported within the DFG priority program 1164, Nano- & Microfluidics (Grant No. Hu 850/2).
