不同刻蚀条件对铜基表面微结构的表面润湿性能影响
Effect of Different Etching Conditions on Surface Wetting Properties of Copper-Based Surface Microstructure
摘要
Abstract
A 60° thread turning tool is used to turn the end face of the copper rod to obtain a regular,controllable and uniform surface microstructure.Turning processing combined with chemical etching and high-temperature oxidation are used to construct nanofilms and 1-Octadecanethiol modification methods to prepare copper-based superhydrophobic surfaces.The effects of etching time and etching temperature on the surface wetting properties of the copper-based surface microstructure are studied.The surface microstructure after turning is observed with a scanning electron microscope(SEM)and the static apparent contact angle of the copper-based superhydrophobic surface is measured with an optical contact angle measuring instrument.The results show that the copper-based surface can form ravines and are evenly distributed in a spiral shape.The submicron or nanoscale rough structure,the static contact angle size of the copper-based superhydrophobic surface and the coverage of the nanofilm increase with the increase of oxidation time and oxidation temperature.The copper-based superhydrophobic surface obtains the best superhydrophobic performance when the chemical etching temperature is 75℃ and the oxidation time is 60 minutes,and the best static apparent contact angle is 165°.The cost of this superhydrophobic surface preparation method is low,the effect is relatively good,and it has a certain promotion effect on the actual production of superhydrophobic surfaces.关键词
