Glass, home bathroom antifog glass, the plane skylight etc. of the display of electronic product and solar cell obtain widely should
With.
At present, the processing method of the super hydrophilic wetability of glass surface mainly has：
1. micro-nano structure is formed in glass surface by nanometer technology, optical etching technology, vapor deposition in situ etc..Such as health
The super array structure using nano aluminium oxide is prepared for the gold with micro-nano array structure in the rafifinal Tunnel-hole template
Belong to nickel nano particle and super hydrophilic nano metal nickel film is made.Such method prepare super hydrophilic glass with preparation process it is simple,
The micro-nano structure that the advantages that micro-nano structure is controllable, and super hydrophilic ability is strong but this method are formed is fragile, it is impossible to there is slight touching,
And instrument cost is higher.
2. by modifying glass surface group the methods of self-assembled monolayers, functionalisation of surfaces.For example, Luo Xiang research and utilizations
Polyallylamine hydrochloride and SiO2Electrostatic self-assembled of the nano-particle on organic glass piece surface prepares super-hydrophobic organic glass.
Super-hydrophilic film prepared by such method, synthesis temperature is low, and film covering is uniform, and chemical composition is homogeneous, but film not antifriction
It wipes, super hydrophilic effect, which is held time, to fall short of.
3. super hydrophilicity is obtained in glass article surface by coated with nano material coating.For example, Yamashita will be molten
Nano-meter SiO_2 prepared by glue gel2It is spin-coated on glass slide and obtains super-hydrophilic coating.Super hydrophilic glass prepared by such method, parent
Aqueous energy is strong, and use scope is wider, but the glass of most coated with nano coatings no longer possesses the simple glass transparency, light transmission
Property.

Kind mechanism；1. under hydrothermal conditions, H2O can attack glass surface Si-O-Si groups and a condensation hydrolysis reaction response occurs such as
Shown in Eq.1, reaction result can cause glass surface covalent to be broken, some small molecules or ion are formed.It is 2. same with this
When have NH3H2The organosiloxane for the OH- attack glass surfaces that O is generated, destroys the reaction of Si-O keys as shown in Eq.2.In this etching
Middle formation some soluble small moleculars and insoluble web-like silicon complex chemical compound, this just into the micro-nano structure of glass surface,
And cover substantial amounts of hydrophilic functional group-OH.
Eq.1Si-O-Si+H2O→Si-OH+OH-Si
Eq.2Si-O-Si(OH)3++NH3·H2O→Si-O-Si(OH)4++NH4 +→Si(OH)4+SiO+NH4 +
Preferably, the solution is the ammonia spirit of 1mol/l.
Preferably, the temperature is 150 DEG C, when the hydro-thermal reaction time is 1 small.
Preferably, the solution is by being added in ethanol/water azeotropic mixture solution made from ammonium hydroxide.
Preferably, in the ethanol/water azeotropic mixture solution, ethyl alcohol：Water=0.87：0.13m3/m3.
