进行了乙醇液滴在柱的结构化表面上的蒸发的研究（微米级的可变尺寸和间距的正方形柱，以及各种间距的圆柱形）。在经调味的全氟癸基三氯硅烷表面上，观察到显著的膜延伸远远超出纯乙醇液滴的初始接触线，最显著的是4微升液滴。在聚对二甲苯涂覆的表面上，对于50体积%乙醇-水混合物的1.5微升液滴观察到类似的吸收膜。该膜充当用于蒸发的附加表面，并且似乎液滴然后充当用于供给膜的储存器，直到蒸发过程完成，而不是蒸发由接触线处的蒸发控制。有膜的液滴具有更高的蒸发速率。
A study was undertaken of ethanol droplet evaporation on structured surfaces of pillars (square pillars of variable dimensions and spacing of order microns, and cylindrical of various spacings). On seasoned perflourodecyltrichlorosilane surfaces, significant films were observed extending far beyond the initial contact line for pure ethanol droplets, most prominently for 4 microlitre droplets. On parylene coated surfaces, similar imbibed films were seen for 1.5 microlitre droplets of 50% by volume ethanol-water mixture. This film acts as an additional surface for evaporation and it appears that the droplet then serves as a reservoir for feeding the film until the evaporation process is completed, rather than evaporation being governed by evaporation at the contact line. The droplets with films show higher evaporation rates.
