Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further details below by concrete embodiment.
As shown in Figure 1, a kind of variable color film comprises first extraction electrode 14, second extraction electrode 11, control system 12 and first basic unit 3, first transparency conducting layer 4, photoelectric conversion layer 5, dielectric substrate 6, electrochromic layer 7, second transparency conducting layer 8, second basic unit 9 of arranging in turn.Described first extraction electrode 14 is electrically connected with first transparency conducting layer 4, and described second extraction electrode 11 is electrically connected with second transparency conducting layer 8.Described control system 12 is used to make first extraction electrode 14 and second extraction electrode 11 directly to be communicated with or makes between first extraction electrode 14 and second extraction electrode 11 connects with the mains.
Described first basic unit 3 and second basic unit 9 can be by polyethylene plastic film or polypropylene screen or polyester plastics film or polyethylene terephthalate (PET) film formations.This embodiment selects for use the PET film as first basic unit 3 and second basic unit 9, and through evidence, its toughness, shock resistance are all fine, have good explosion-proof effect.Described first transparency conducting layer 4 and second transparency conducting layer 8 can be the SnO of indium tin metal oxide (ITO) or doped with fluorine
2(FTO) film.Described photoelectric conversion layer can be made of zinc ferrite-titania.Described dielectric substrate is by polymeric matrix polymethylmethacrylate (PMMA), lithium salts (LiClO
4) and plastifier polycarbonate (PC) composition, dielectric substrate of the present utility model can be finished ion transfer and ion storage simultaneously.Therefore the utility model need not to be provided with ion storage layer again, has simplified the structure of variable color film.Described electrochromic layer can be by tungstic acid (WO
3) constitute.
The number of described first extraction electrode 14 and/or second extraction electrode 11 has at least two respectively.Because can there be internal resistance in first transparency conducting layer 4 and second transparency conducting layer 8, by being set, at least two extraction electrodes can make the voltage that is added on the electrochromic layer 7 more even, the variable color of electrochromic film is also more even, has overcome the uneven shortcoming of existing variable color film variable color.
As shown in Figure 2, described control system 12 comprises straight-through branch road, second branch road and selector switch 18.Described selector switch 18 is used to make straight-through branch road to link to each other with second extraction electrode 11 with first extraction electrode 14 or second branch road is linked to each other with second extraction electrode 11 with first extraction electrode 14.Described second branch road comprises power supply 16, the variable resistor 17 of mutual series connection.Described selector switch 18 is a single-pole double-throw switch (SPDT), can control switching to single-pole double-throw switch (SPDT) by remote control mode, so that the user operates.
Above-mentioned variable color film also comprises pressure-sensitive adhesive layer 2, release rete 1 and wearing layer 10, described pressure-sensitive adhesive layer 2 is between the release rete 1 and first basic unit 3, the pressure sensitive adhesive of described pressure-sensitive adhesive layer has very strong adhesive aggregation effect to glass, when glass is broken, can cling glass fragment, the people in order to avoid glass fragment splashes around the injury.Described release rete 1 can be made of the PET film that scribbles mould release.Described wearing layer 10 is positioned at second basic unit, 9 outsides, and promptly second basic unit 9 is between the wearing layer 10 and second transparency conducting layer 8.Described wearing layer can adopt that a kind of ultraviolet (UV) is coating material solidified to solidify to form through UV.
