摘要:本发明公开了一种稳定超双疏表面的制备方法,是以醇-水混合溶液为介质,以酸或碱作为催化剂,有机硅烷混合物与纳米粒子进行水解缩合反应,得到有机硅烷聚合物/纳米粒子复合物悬浮液;再将有机硅烷聚合物/纳米粒子复合物悬浮液喷涂于基底表面形成涂层,然后通过热固化处理,既得稳定超双疏表面。以5μL水滴和油滴测定接触角和滚动角,结果:水接触角> 160°,滚动角< 2°;癸烷接触角> 155°,滚动角< 10°。采用细砂磨损、高压水柱冲击、有机溶剂浸泡、高低温和紫外线照射等损坏超双疏表面后,测定对水和油滴接触角和滚动角的影响,发现本发明制备的超双疏表面具有优异的机械、化学和环境稳定性。 |

Abstract: A preparing method of a stable superamphiphobic surface is disclosed. The method includes subjecting an organosilane mixture and nanometer particles to a hydrolytic condensation reaction by adopting an alcohol-water mixed solution as a medium and adopting an acid or an alkali as a catalyst to obtain organosilane polymer/nanometer particle composite suspension; spraying a substrate surface with the organosilane polymer/nanometer particle composite suspension to form a coating; and performing thermal curing treatment to obtain the stable superamphiphobic surface. Contact angles and roll angles are measured by using 5 muL of a water drop and an oil drop, and results show that the water contact angle is larger than 160 degrees, the water roll angle is smaller than 2 degrees, the decane contact angle is larger than 155 degrees, and the decane roll angle is smaller than 10 degrees. After the superamphiphobic surface is damaged by fine-sand abrasion, high-pressure water column shock, dipping with organic solvents, high and low temperatures, ultraviolet irradiation, and the like, influences on the contact angles and the roll angles of the water drop and the oil drop are measured, and results show that the superamphiphobic surface prepared by the method has excellent mechanical, chemical and environment stability. | |
