Abstract

The invention discloses a temperature control fenestrated membrane and a making method thereof. The temperature control fenestrated membrane comprises a spectrum-selective membrane, doped membranes and a flexible basal membrane, wherein the doped membranes are arranged on the two side surfaces of the spectrum-selective membrane; the flexible basal membrane is arranged on the VO2 doped membrane on one side of the spectrum-selective membrane. According to the temperature control fenestrated membrane and the making method thereof, the VO2 membranes are formed on the two side surfaces of the spectrum-selective membrane, the property that the VO2 membranes in the metallographic phase under high temperature reflect infrared rays while in the semiconductor phase under low temperature enable the infrared rays to penetrate through is utilized, and through the doping technology, the phase-transition temperature of the VO2 doped membranes is reduced to room temperature, so that the purpose of automatically regulating the infrared transmission according to the indoor temperatures is achieved, and the control precision of the intelligent fenestrated membrane on the transmittance of the infrared rays is further improved.

Description

technical field [0001] The invention relates to the technical field of window films, in particular to a temperature-controlled window film and a method for manufacturing the temperature-controlled window film. Background technique [0002] At present, energy conservation and emission reduction has become one of the important ways to deal with the greenhouse effect and global climate change. The energy consumption required for temperature regulation in the field of automobiles and buildings is huge, and 70% of the incident heat into the room is transmitted through the windows. Sticking a layer of window film on the inner surface of automobile or building glass can effectively block infrared rays and ultraviolet rays, keep visible light through, and reduce energy consumption of air conditioners. In addition, window film can also reduce the damage caused by ultraviolet radiation in the car or indoor objects and personnel. [0003] Methods of preparing window films include wet...
