Enter in above-mentioned solution, continue ultrasound 5min；（4）At room temperature, 5ml butyl titanates are instilled in the above-mentioned solution containing fabric,
65 DEG C are warming up under ultrasonic state.After ultrasonic 2h, silicon dioxide gel is slowly added in above-mentioned solution, continues ultrasound at 65 DEG C
2h；（5）Fabric is finally taken out, is dried at 80 DEG C, is cured at 120 DEG C, obtains titania/silica/graphene oxide
Fabric after arrangement.
The preparation method of tri compound coated fabric of the present invention, step（1）The drying temperature is 60 DEG C.Step
（2）The sonication treatment time is 1h.
The preparation method of tri compound coated fabric of the present invention, step（4）The instillation speed of the butyl titanate
For 50 μ L/s.Step（4）The addition speed of the silicon dioxide gel is 2-3 drops/s.
The preparation method of tri compound coated fabric of the present invention, step（5）The drying time is 5min.Step
（5）The hardening time is 3min.Under illumination condition, titanium dioxide valence-band electrons are excited to conduction band, electronics and hole to
Surface migration, in Surface Creation electron hole pair.Electronics and Ti4+Reaction, hole are then reacted with surface bridge oxonium ion, are generated respectively
Ti3+And Lacking oxygen.At this time, the water decomposition in air, is adsorbed in Lacking oxygen, becomes chemical absorbed water, i.e., around Lacking oxygen
Form hydrophily microcell.Chemical absorbed water can further adsorb the moisture in air, form physics adsorption layer.Titanium dioxide table
The nanostructured characteristic in face makes above-mentioned reaction further strengthen, and equally distributed nanoscale is constituted in titanium dioxide surface
Hydrophilic microcell and hydrophobic microcell, similar to bidimensional capillary structure.Since the drop size of water is much larger than these microcell areas, institute
Water-wet behavior is shown with macroscopically titanium dioxide surface.Titanium dioxide is subject to burst of ultraviolel, and the valence-band electrons of semiconductor occur
Band-to-band transition, i.e., transit to conduction band from valence band, so as to produce light induced electron (e-) and hole (h+).Adsorb at this time in nano particle
The dissolved oxygen trapped electron on surface forms superoxide anion, and hole will adsorb hydroxide ion and water oxygen in catalyst surface
It is melted into hydroxyl free radical.Superoxide anion and hydroxyl free radical have very strong oxidisability, can be by most of organic matter oxygen
It is melted into final product carbon dioxide and water.Methylene blue absorbance in non-coated fabric has almost no change, and tri compound
Coated fabric is 92% to the degradation rate of methylene blue.After 30 washings, fabric becomes the palliating degradation degree of methylenum careuleum without obvious
Change, degradation rate still reaches 91.5%.Therefore, experimental result further demonstrates that, through composite nano-granule on tri compound coated fabric
Son forms good adhesion with fabric, after 30 washings, still maintains higher methylene blue degradation rate, washability is excellent.
Ultrasonic wave also enhances the photocatalysis performance of nano-particle, the degraded before ternary coating fabric washing prepared by ultrasonic method to fabric
For the standby ternary coating fabric of two rolling of the leaching of rate 97% to two to the degradation rate 90% high 7% of methylene blue, analysis reason is photocatalyst
Due to the presence of its surface force between grain, make them be easy to reunite, form larger aggregate, destroyed using supersonic oscillations
Coulomb force and Van der Waals force in aggregate between particle, the aggregate being scattered in medium are opened, so that little particle point
Cloth is evenly.On the one hand it is that supersonic oscillations are stripped of the material that titanium dioxide surface is deposited on mulching method, reduces pair
The stop of light, transmission depth increase so that the quantity increase in photoinduced electron hole pair so that catalytic activity improves；On the other hand,
Supersonic oscillations are handled so that a certain amount of overstrain and position change defect are generated in catalyst granules, so that titanium dioxide energy
Gap width reduces；Furthermore ultrasonic wave produces violent shock wave and microjet in photocatalyst solution, can not only solve nanometer
Photocatalyst particle reunite and solution inside it is uneven the problems such as, the aggregate being scattered in solution can also be opened so that
Photocatalyst particle granularity reaches nano-scale dimension, and is evenly distributed.
Tri compound coated fabric has excellent photocatalysis performance, and coated fabric prepared by ultrasonic method under visible light
With stronger washing fastness, the mechanism that ultrasound strengthens nano-particle insertion fabric is further analyzed, mainly in terms of two
Analyzed, be on the one hand the effect of main acoustic radiation force and infrasonic radiation power, be on the other hand acoustic cavitation effect, caused more
Nanoparticle aggregation in fabric.In addition to ultrasonication, the hydroxyl group and nano-particle of fabric face form interface
With reference to also so that forming stronger combination power between nano-particle and fabric.
