Standby super hydrophobic surface, executes following step.Firstly, cleaning base component 1 with water and soap, base component is immersed water-bath and adding
It carries with ultrasound about 10 minutes.After having rinsed base material 1, base material 1 is again dipped into clear water and is loaded with ultrasound
10 minutes.Next cleaning includes immersing base material 1 in ethyl alcohol and loading it with ultrasound 10 minutes.Finally,
With the dry base material 1 of compressed air.Next, with ozone treatment base material 1 to remove any organic residue and exposure
The OH group of glass material.
Then, one or more than one silica containing layer is deposited to by base component by combustion chemical vapor deposition
On 1.The step is generated by so-called pyrolysis silicon technology by SiO2The unformed layer 2 of composition.Being pyrolyzed silicon is organosilane based precursor,

Due to used system, the SiO of deposition2Amount it is directly related with the number or duplicate number passed through.However,
It must be stressed that key factor be not necessarily by number but deposition pyrolysis silicon/SiO2Amount.In other words, lead to
The number crossed and the thus quantity of layer 2 depend on the desired characteristic of the subsequent purpose of base component 1, layer 2, and are used to form layer
2 system and parameter.It, can be with the roughness on the surface of measurement layer 2 by means of such as field emission scanning electron microscope (FESEM)
And it can be by assessing SiO2The size and amount of crystal grain analyze the SiO of deposition2Amount.
In the case where passing through for execution 1 time, the SiO of diameter about 20nm is formed2The aggregation of particle and 5 to 10 particles.
As long as subsequent thicker layer 2 will be deposited, so that particle can be gathered into bigger by the more pyrolysis silicon of middle addition
Grain.In the case where passing through for execution 2 times, the medium size of these aggregated particles is about 100nm, and pass through at execution 4 times
In the case of, the medium size of these aggregated particles is about 200nm.If by different pyrolysis silicon be used for it is different pass through, can
To deposit multiple and different layers 2.
Fig. 2 shows the schematic cross sectional views of base component 1, the base component 1 is further coated using silicon fluoride.
Silicon fluoride (or fluorinated silane) is applied to reduce the surface tension on surface.Two kinds are deposited by using two different methods
Different silicon fluorides.In general, both methods can be used alternatively or additionally, but generally preferably use chemical vapor deposition
(CVD)。
1) PFOTESi dip-coating
Base material 1 was immersed with different duration (10 minutes or 60 minutes) and contains 1H, 1H, 2H, three second of 2H- perfluoro capryl
Oxysilane (PFOTESi) (has 1 volume %, 5 volume %, 10 with various concentration in fluorated solvent (HFE-7100)
Volume %) solution in.One or more than one super-hydrophobic top layer 3 with different thickness is formed as a result,.
2) PFOTCSi CVD is coated
Under about 100 millibars of vacuum, base material 2 is placed in 10 drops trichlorine (1H, 1H, 2H, 2H- perfluoro capryl)
1 hour in the reactor (English: dissecator) of silane (PFOTCSi).Since PFOTCSi and the moisture in remaining atmosphere are anti-
Answer, silicon fluoride is hydrolyzed, to form silanol, the silanol then with other silanol molecules and SiO2Free OH in layer 2
Condensation reaction occurs for group.Silicon fluoride thus with before by pyrolysis pasc reaction formed amorphous Si O2Layer 2 is with covalent linkage
And form super-hydrophobic top layer 3.Silicon fluoride layer 3 is the thin layer for following the topology of pyrolysis silicon granular bedding 2.
As last post-processing, coated base material 1 is heated to about 110 DEG C about 10 minutes, to promote water
The condensation of evaporation and unreacted silanol groups.Finally, with acetone clean base material 1, with remove any unreacted silane,
Silanol or other compounds.
Other than FESEM, the topological shape of layer 2,3 obtained can be analyzed by atom/scanning force microscopy (AFM)
Looks, to determine SiO2The size of particle and the roughness for determining layer 2 or layer 3.Coated base portion is shown in following table 1
The quadratic average roughness value R of material 1RMS.As can be seen that increasing of the roughness on surface with the number of pass times of pyrolysis siliceous deposits
Add and increases.For having 4 pyrolysis siliceous deposits passed through, roughness is 1 about 5 times passed through.
Table 1: r.m.s. roughness with pyrolysis siliceous deposits number of pass times variation
The roughness and SiO on surface2The amount and size of particle in relation to and the thus wettability with water contact angle and surface
It is related.In short, not only improving the adhesion of succeeding layer 3, Er Qieshi by using the pyrolysis siliceous deposits controlled in the following manner
Show high hydrophobicity, even superhydrophobic surface behavior: being pyrolyzed silicon/SiO by changing the number passed through and thus changing2's
The surface concentration and roughness of the size and particle of amount and particle control pyrolysis siliceous deposits.If the side passed through with 3-4 times
Formula deposition pyrolysis silicon and/or if the SiO deposited2The size of aggregated particle be about 100nm to 200nm and if secondary flat
Equal roughness value RRMSIn about 50nm between 80nm, then this effect is maximized.
In the case where depositing in a manner of pyrolysis silicon by 1 time, although surface is that " just " has hydrophobicity, water
Contact angle significantly increases.In the case where passing through for 2 times, there is second of increase for realizing surface super-hydrophobic, and 3 to 4
It is secondary pass through in the case where, water contact angle stablize at 167 ° or so.In addition, super-hydrophobic by being formed by using 3-4 pyrolysis silicon
Surface is proven to have extremely low slide angle.It is shown in following table 2 in different pyrolysis silicon number of pass times (with pyrolysis silicon
Amount it is directly related) under water contact angle and slide angle result.
