Spontaneous Droplet Motion on Structured Surfaces with Curved and Straight wedges

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.

本数据为Wang等人发表于《Advanced Materials Interfaces》2020年（DOI: 10.1002/admi.202000520）的论文《基于定制楔形结构设计提升结构化表面液滴自发运动》补充视频的原始实验数据。
本数据集为验证所提理论模型的实验录制视频，该模型用于预测带有直楔形与曲楔形结构的图案化表面上的液滴自发运动。
所设计的楔形结构可通过如下轮廓函数描述（单位：mm）：曲楔形为 y = 0.009775 x² + 0.01534 x − 0.03014；直楔形为 y = tan(3°)x + 0.2661。
– 视频"curve 5ul"对比了放置在曲楔形结构上、距楔形尖端x0位置处的5毫升液滴的运动过程；
– 视频"curve x0 4.7mm"对比了在曲楔形结构上、距楔形尖端x0=4.7mm位置处放置的体积为3、4、5毫升的液滴的运动过程；
– 视频"straight 5ul"对比了置于直楔形结构上、距楔形尖端x0位置处的5毫升液滴的运动过程；
– 视频"straight x0 6.0mm"对比了在直楔形结构上、距楔形尖端x0=6.0mm位置处放置的体积为3、4、5毫升的液滴的运动过程。
