Description

Original data for Supplementary Videos of "Enhancing Spontaneous Droplet Motion on Structured Surfaces with Tailored Wedge Design" by Wang et al., Adv. Mater. Interfaces. 2020 (doi: 10.1002/admi.202000520). The data are video recordings during experiments designed to verify the proposed theoretical model on prediction of spontaneous droplet movement on patterned surfaces with straight and curved wedges. The designed wedges can be described by the profile functions y = 0.009775 x^2 + 0.01534 x − 0.03014 (in mm, "curved wedge") and y = tan (3°)x + 0.2661 (in mm, "straight wedge"). – video “curve 5ul” compares the motion of 5 ml droplets placed on the curved wedge at three positions x0 away from the wedge tip; – video “curve x0 4.7mm” compares the motion of droplets of volume 3, 4 and 5 ml placed on the curved wedge at x0= 4.7 mm from the wedge tip; – video “straight 5ul” compares the motion of 5 ml droplets placed on the straight wedge at three positions x0 away from the wedge tip; – video “straight x0 6.0mm” compares the motion of droplets of volume 3, 4 and 5 ml placed on the straight wedge at x0= 6.0 mm from the wedge tip.
