Electric-control color-changeable glass

The utility model discloses electrically controlled color-changeable glass which has the key point that a layer of polypropylene alcohol clamping glue (2) and (6) is separately coated on the inner side of each of two layers of ordinary glass (1) and (7), and a layer of tin peroxide indium thin conductive films (3) and (5) is separately sandwiched on the inner side of each of two layers of polypropylene alcohol clamping glue (2) and (6); afterwards, electrically controlled color-changeable polymethyl methacrylate polymers (4) are led between the two layers of tin peroxide indium thin conductive coating layers to form the electrically controlled color-changeable glass. In the process of using the utility model, the light transmittance of a PMMA can change along with the change of voltage when the voltage is added to the conductive thin films. Compared with the prior art, the utility model can regulate the light transmittance by means of the action of electricity and can play the role of intellectualized official or household business. Simultaneously, the utility model can absorb the element of ultraviolet radiation in sunlight to achieve the effect of protecting against the ultraviolet radiation.
