氧化还原法制备超疏水表面及其防覆冰性能
|
摘要
使用化学氧化还原法制备出疏水性能优异的超疏水表面,使用接触角测量仪、扫描电镜对表面浸润性及形貌进行表征分析。制得的铝基体超疏水表面接触角高达163.31°,滚动角小于5°。探究不同反应时间对表面形貌和浸润性的影响,使用自制的结冰监测系统对制备出的超疏水表面的静态和动态水滴防覆冰性能进行探究,并结合一维传热理论和经典成核理论对实验结果进行分析。结果表明,反应80min时表面疏水效果最好,超疏水表面静态水滴延缓结冰时间约是普通样品的5倍,结冰温度也低了3.3℃,动态水滴撞击表面时,超疏水表面始终无积水和覆冰,表现出优异的静态和动态防覆冰性能。
Superhydrophobic surfaces with excellent hydrophobic properties were prepared by chemical redox process. The surface wettability and morphology were characterized and analyzed by contact angle measurement and scanning electron microscopy(SEM). The contact angle of the superhydrophobic surface is as high as 163.31°, and the sliding angle is less than 5°. The effect of different reaction time on surface morphology and wettability was investigated, the performance of the static water droplets and the dynamic anti-icing performance of the superhydrophobic surface was explored by using a self-made icing testing system, and the experimental results were analyzed by combining the one dimensional heat transfer theory and classical nucleation theory. The results show that the surface hydrophobicity is the best when the reaction is 80 min. The delay icing time of static water droplets on superhydrophobic surface is about 5 times than the normal sample, icing temperature is also low 3.3℃. There is no accumulated water and ice from start to end on superhydrophobic surface when water droplets impacting the cold surface. The as-prepared superhydrophobic surfaces show excellent static and dynamic anti-icing performance.
