Description
Technical field
The present invention relates to glass technology fields, specifically disclose a kind of preparation method of hydrophilic glass product.
Background technique
The wetability of material surface is always the hot spot of academic and industrial circle concern, super hydrophilic and super-hydrophobic as two kinds of poles
Special wetting phenomena is held, has attracted the extensive research of domestic and foreign scholars in recent years.In general, super hydrophobic surface refers to solid-liquid
Contact angle is greater than 150 ° of surface.On the contrary, ultra-hydrophilic surface refers to that liquid can be spread completely, and cause contact angle be equal to or
Close to 0 ° of surface.Compared with super-hydrophobic research, super hydrophilic aspect research it is less, but due to the unique wetting of ultra-hydrophilic surface
Feature, so that ultra-hydrophilic surface has many advantages, such as automatically cleaning, high heat transfer.Earliest it is found out that super hydrophilic characteristic is based on two
The photocatalysis characteristic of titanium oxide, after by ultraviolet light, water and titanium dioxide semiconductor film contacts, contact angle be reduced rapidly to
0±1°.Its principle is that the bridge location oxygen of titanium dioxide surface generates active oxygen radical after by ultraviolet excitation, and life is reacted with hole
At oxygroup hole, water, which is adsorbed in oxygroup hole, becomes chemical absorbed water, to form equally distributed nanoscale on surface
Hydrophilic microcell.This super hydrophilic property has important application in terms of antifog glass, self-cleaning glass.However, titanium dioxide is thin
Film for the significant drawback of self-cleaning glass is restricted by illumination condition, that is, must have under conditions of light irradiates could send out
Wave super hydrophilic characteristic.In view of the above problems, special to propose this invention.
