Directional transport property and repellency of artificial sweat liquid on the superhydrophobic finished fabric after selective plasma treatment.

Caption

(A and B) Still frames taken from videos when sweat droplet was dripped onto (A) exposed top spot and (B) unexposed back spot areas under a flow rate of 10 μl/min. The fabrics were originally laid horizontally and then were rotated clockwise to certain inclined angles. The back spot was tested via dripping sweat liquid initially upward against the gravity. (C) Transport behavior of a first sweat droplet when being dripped upward to the back spot of the horizontally laid fabric. Movie credit: Lihong Lao, Cornell University.
