Abstract

The aim of this research is to create self-cleaning hydrophobic and superhydrophobic surfaces (SHS) on a glass substrate. Carbon soot has been deposited from the candle flame in order to manufacture a SHS on glass slides. The water contact angle (WCA) and roll-off angle were measured after carbon soot deposition using a test rig built in the laboratory. Further, to make SHS on glass slides more robust, candle wax and vassilline were applied on a glass substrate with or without roughening it using emery paper of grade (P80, P220 & P400). The highest WCA was 160° for a candle sooted on glass roughened with emery paper of grade P80 using vassilline as an adhesive. The mechanical durability of the prepared surfaces has been investigated using a peel-off technique with highly glue adhesive tape. The WCA was measured after each peel-off to check the changes in the degree of wettability of the fabricated surface. From the investigation, it has also been observed that more roughened glass slides show more resistance to the removal of carbon soot.

用碳烟和不同胶粘剂制备超疏水表面及评价

本研究的目的是在玻璃基板上创建自清洁疏水和超疏水表面(SHS)。为了在玻片上制造SHS，从蜡烛火焰中沉积了碳烟。利用室内搭建的实验台架，测量了碳烟沉积后的水接触角和滚转角。此外，为了使玻璃载玻片上的SHS更加坚固，将蜡烛蜡和瓦士林涂在玻璃基板上，使用等级(P80, P220和P400)的金刚砂纸进行或不进行粗化。用瓦西里啉作为粘合剂，用P80级金刚砂纸磨粗玻璃上的蜡烛，WCA最高为160°。采用高胶胶带的剥离技术研究了所制备表面的机械耐久性。在每次剥离后测量WCA，以检查制造表面润湿性的变化程度。从调查中还观察到，越粗化的玻片对碳烟的去除表现出更大的阻力。
