Description
Technical field
The invention belongs to Treatment of Metal Surface and its technical field of modification, are related to a kind of for the special of drop directed transport
The preparation method on wellability surface.
Background technique
Wetability is a kind of important interfacial phenomenon of the surface of solids, and moistened surface degree depends on its chemical component and microcosmic
Form and geometry.There are two the factor of influence surface of solids wellability is main：（1）Surface free energy；（2）Rough surface
Degree.When surface free energy reduces, hydrophobic performance will enhance.However, even if the smooth surface with minimum surface energy,
Also only have 119 ° with the contact angle of water.Better hydrophobic effect in order to obtain needs surface to have certain roughness.It is super-hydrophobic
The research on surface and the correlated phenomena of high contact angle can trace back to a very long time, and researcher can prepare it is close
Perfect air-water interface（Contact angle is 180 °）Super hydrophobic surface.In addition, super hydrophobic surface has such as antifrost, drag reduction
And the features such as automatically cleaning, these outstanding characteristics show huge value, such as transparent hydrophobic coating in practical applications（For
Vehicle glass）, water-oil separating, anticorrosion, droplet manipulation etc..Wherein in droplet manipulation field, the transport of drop orientation especially by
The concern of researcher.Due to the special nature of the contact between solid-liquid two-phase, conveying of a small amount of liquid on solid is not one
Simple process.Solution to this problem mainly has following three kinds：
First method is the adhesion strength for changing super hydrophobic surface, to microlayer model be adhered on super hydrophobic surface, Ke Yitong
It crosses and moves the super hydrophobic surface with high adhesive force to move drop.
Another method is to wrap up drop using hydrophobic powder." liquid bead " made of being wrapped up as hydrophobic powder
It can be considered as one soft " class solid globules ", this bead significantly reduces the adhesiveness to the surface of solids.To " class
The movement that solid globules " can orient under the action of gravity, electric and magnetic fields.
It is using super-hydrophobic track there are also a kind of more direct approach.This is a kind of simple and effective method：Flat
The track with certain depth is carved out on face, then makes entire plane（Including track）With superhydrophobic characteristic, drop can be with
Using gravity or electrostatic force as driving force, make directed movement on super-hydrophobic track.But use simple super-hydrophobic track
Carrying out droplet transport has very strong limitation.Track super-hydrophobic first has certain depth, this means that needs have
It is processed in the plane of certain thickness, this brings very big challenge to the micro- plane machining of MEMS.In addition to this, due to about
Beam drop derives from the vertical walls of track without departing from the power of track, and drop is very easy to deviate super-hydrophobic track, this makes liquid
The movement velocity dripped on super-hydrophobic track cannot be excessive.
Therefore, a kind of simple, efficiently quick, conducive to drop orientation transport the special wellability surface of preparation method is developed
Preparation method have very important significance.
Summary of the invention
The object of the present invention is to provide a kind of preparation method on the special wellability surface of drop directed transport, this method exists

The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of preparation method on the special wellability surface of drop directed transport, as shown in Figure 1, the special infiltration surface of its preparation
It include mainly hydrophobic substrate 1, super hydrophobic surface 2 and super hydrophilic channel 3, specific preparation process is as follows：
（1）There is the ultra-hydrophilic surface of micro-nano collaboration diadactic structure in smooth hydrophobic substrate material surface preparation；
（2）Using the method for surface modification（That is the method for chemical modification or coating）To step（1）The ultra-hydrophilic surface of preparation into
Row modification forms super hydrophobic surface in ultra-hydrophilic surface to reduce the surface energy of ultra-hydrophilic surface, so that the super hydrophilic table of preparation
Face obtains superhydrophobic characteristic；
（3）Superfine, the extremely shallow super hydrophilic track that width is 30 ~ 100 μm, depth is 30 ~ 100 μm is prepared in super hydrophobic surface,
The surface texture and low-surface-energy decorative material that script is destroyed by laser carving method make track have super hydrophilic characteristic.
Super hydrophobic surface with hydrophilic track is tilted a certain angle, Van der Waals of the drop between gravity, capillary force and fluid molecule
Under power collective effect, realize that drop carries out directed transport on the super hydrophilic track of preparation.
In the present invention, ultra-hydrophilic surface can be processed using the methods of etching, hydrothermal synthesis, electrochemistry.
In the present invention, super hydrophilic track can be processed using the methods of fine laser processing, machining or scribing,
The super hydrophilic track of processing can be straight line and be also possible to arbitrary graphic structure.
In the present invention, super hydrophilic track can be continuous micron trenches shape structure, be also possible to by discontinuous micron
The discontinuous structure of grade dot matrix permutation composition.
Compared with the prior art, the invention has the advantages that：
1, surface prepared by the present invention possesses super hydrophilic track, super hydrophobic surface, so that the resistance that rubs when drop is moved along track
Power is very small, as long as the angle of inclination very little can be realized as the directed transport of drop.
2, preparation method of the present invention is simple, can use existing super-hydrophobic preparation process, by processing fine surpass
The directed transport of drop can be realized in hydrophilic channel.
3, method of the present invention relative to traditional super-hydrophobic channel drop directed transport, surface are tilting biggish angle
Degree, in the case where liquid drop movement fast speed, hydrophilic channel, which still is able to hold onto drop, prevents it from de-orbiting, limiting case
Under, sizeable drop remains to move along super hydrophilic track with faster speed when surface tilts 90 °.
