Abstract
The utility model provides electrochomeric glass equipped with a WO3 film as the electrochomeric film thereof and a NiO film as an ion-providing layer thereof. Meanwhile, a blending mixture of a random copolymer P (Vac-Ma) prepared by vinyl acetate and methyl acrylate as monomers and polymethyl methacrylate (PMMA) are adopted as the ion conductive layer of the electrochomeric glass so as to manufacture sandwich-type electrochomeric glass. The adjustable voltage of the electrochomeric glass is provided by a solar energy battery, so that the color change of the electrochomeric glass can be realized. The electrochomeric glass can selectively absorb or reflect the external thermal radiation so as to prevent the internal heat radiation diffusion. Therefore, the energy consumed for the temperature adjustment of office buildings and residential buildings is reduced. The electrochomeric glass has the advantages of simple manufacture, low cost, easy manufacture method and good practicability, which is suitable for large-scale industrial production.
Description
Technical field
The present invention relates to a kind of preparation method of electrochomeric glass, relate in particular to by changing and provide voltage by solar cell, and then the preparation method of control electrochomeric glass.
Background technology
" energy crisis " is the word that present scientist in the world widely pays close attention to.Buildingss such as office block and residential building keep nice and cool warm with the maintenance in winter in summer at present, must realize by using air-conditioning or heating installation, thereby expend many energy, and the used freon contaminated air of air-conditioning, can cause the ozone cavity, the earth is produced huge harm.Reach energy-saving effect for the energy of interior of building can be exchanged freely with space outerpace smoothly, people by change interior of building finishing and a large amount of use glass make decoration.From then on adhering film to glass miscellaneous arises at the historic moment, and adhering film to glass on the market mainly contains TiO now
2(Titanium dioxide) glass-film, adhering film to glass, common electrochomeric glass, liquid crystal color-changing glass.TiO
2Glass-film, its shortcoming of adhering film to glass be can not coloured and colourless between change; Common electrochomeric glass color changeable effect is poor, and the reaction time is slow; And liquid crystal color-changing glass cost an arm and a leg and perishable.The voltage of above-mentioned these electrochomeric glass all needs additional power source that voltage is provided, and causes energy resource consumption, and installing to change also has certain difficulty.
Sun power has inexhaustible advantage as new green power.Solar cell can directly be converted to electric energy with sun power, can not produce any pollution to environment.Solar cell does not have the restriction of the region and the energy, has the place of sunlight to use, and convenient and safety.The solar cell kind is many, and on the largest scale mainly is silicon solar cell.The silicon solar cell characteristics are that avirulence, conversion efficiency height, long service life and stability are better.Silicon solar cell comprises monocrystalline silicon and polysilicon solar cell.The silicon solar cell photoelectric transformation efficiency that common commercial is used generally reaches 13%～16% and to be used in the lower devices of power consumption demand such as computing machine and wrist-watch maturely.
In sum, existing method is failed the product that each is emerging and is combined preferably, causes emerging product can better not come into operation, the energy dissipation of using outmoded equipment also to cause.
The utility model content
At the defective that exists in the above-mentioned prior art, the invention provides a kind of sun power control electrochomeric glass device and preparation method thereof.This electrochomeric glass is made up of two-layer FTO (Fluorine-doped Tin Oxides) or ITO electro-conductive glass such as (Indium Tin Oxides), the conductive layer of two-layer electro-conductive glass is relative, the centre accompanies electrochromic film in order, ion provides layer and ionic conduction layer, and electrochromic film adopts WO
3Film, ion provide layer to adopt the NiO film, and it is the random copolymers P (Vac-Ma) of monomer preparation that the ionic conduction layer adopts with vinyl acetate and methyl acrylate, with the blend of polymethylmethacrylate (PMMA).Two ends encase with epoxy resin, and lead is drawn at the place at conductive layer, and connect solar cell voltage is provided.
The present invention utilizes solar cell to produce voltage and this voltage is used to control electrochomeric glass.The Control of Voltage that solar cell produces+2V～-2V between, utilize adjustable resistance to change the variation of the voltage of whole electrochomeric glass, and then change the situation of the variable color of electrochomeric glass.
WO required for the present invention
3Film, P (Vac-Ma)/PMMA film, the NiO film is with low cost, and manufacture craft is simple.The finished product color changeable effect is good, and the reaction time is fast, and not perishable, is applicable to big production.WO
3But the off-color material absorbing wavelength is than the light of short-wave band, and reflection wavelength is than the light of long-wave band, and is therefore fine to the regulating effect of light, thereby can selectivity absorb or reflection External Heat Flux and prevention internal heat radiation diffusion.
