The invention has the characteristics that the method is light in pollution and low in cost and easy to operate, complex instruments and equipment are not required, and the method is suitable for large-scale industrial production.
Description
Technical field
The present invention relates to metal surface properties modification, particularly a kind ofly prepare the method that the base steel height is sticked super hydrophobic surface
Background technology
Super hydrophobic surface is meant that water droplet contact angle above that surpasses 150 ° surface; Can be divided into low super hydrophobic surface (roll angle＜10 °) and the height of sticking according to the size of roll angle sticks super hydrophobic surface (no roll angle, sample are overturn, and water droplet still can be attached on its surface after 180 °.The common low super hydrophobic surface that sticks of occurring in nature has lotus leaf, paddy rice leaf, water skipper leg etc.; Common height sticks super hydrophobic surface has peanut leaf, roseleaf and some animal pin such as gecko, fly, honeybee, locust etc.
Present discover that the low super hydrophobic surface that sticks can be applicable to aspects such as drag reduction, freezing frosting, corrosion-resistant, automatically cleaning, and highly stick the harmless transfer that super hydrophobic surface can be applicable to liquid.Because steel extensive use in military industry and civilian industry, and its price is more cheap, and therefore, the preparation steel matrix is hanged down and sticked super hydrophobic surface and height and stick super hydrophobic surface and have certain application prospect.Although existing at present several different methods can be used for preparing the steel matrix super hydrophobic surface, these super hydrophobic surfaces are low stick super hydrophobic surface (Guo F., Su X.J.; Hou G.L., Li P., Applied Surface Science; 2012,258, pp.4906-4910; Song H.J., Shen X.Q., Ji H.Y., Jing X.J., Appl.Phys.A, 2010,99, pp.685-689; Yang H., Pi P.H., Cai Z.Q., Wen X.F., Wang X.B., Cheng J., Yang Z.R., Applied Surface Science, 2010,256, pp.4095-4102; ).At present, about sticking super hydrophobic surface, artificial metal's matrix height mainly concentrates on (Li J., Liu X.H., Ye Y.P., Zhou H.D., Chen J.M., J.Phys.Chem.C, 2011,115, pp.4726-4729 on copper, zinc and the titanium matrix; Li J., Yang Y.X., Zha F., Lei Z.Q., Materials Letters, 2012,75, pp.71-73; Lai Y.K., Gao X.F., Zhuang H.F., Huang J.Y., Lin C.J., Jiang L., Adv.Mater., 2009,21, pp.3799-3803; ), and on the more cheap steel matrix of price the preparation height stick super hydrophobic surface also Shang Weijian report is arranged.Therefore, inventing a kind of simple effective method prepares the base steel height and sticks super hydrophobic surface and be necessary.
Summary of the invention
The purpose of this invention is to provide a kind of simple and effective method that the base steel height is sticked super hydrophobic surface for preparing.
The technical scheme that the present invention adopts comprises the steps:
(1) steel plate is cleaned oil removing, carry out rubbing down then, re-use ultrasonic waves for cleaning; The steel plate that is adopted can not be a stainless-steel sheet;
(2) will handle clean steel plate and be immersed in and be no less than 20s in the copper sulfate solution, and make the surface deposit layer of copper equably;
(3) steel plate behind the deposited copper is immersed in the stearic acid ethanolic solution is no less than 24h, take out the back and obtain the base steel height with absolute ethyl alcohol flushing, oven dry back and stick super hydrophobic surface.
The present invention has following characteristics:
(1) method of the present invention is not used strong acid, highly basic, and is little to the harm of operating personnel and environment.
(2) the bright method of this law need not complex instrument equipment or expensive raw material, is suitable for large-scale industrial production.
(3) the base steel height that obtains of method of the present invention is sticked super hydrophobic surface the contact angle of water is reached 163.3 °, demonstrates high super-hydrophobicity, and the adhesion to water droplet is stronger simultaneously, and when 90 ° of surface tilt or 180 °, water droplet still can't tumble.
