Recently, the European solargain R & D team has developed polymer plastic films with energy saving of more than 90%. According to the characteristics of polymer materials absorbing specific light wavelengths, the team has successfully developed commercially feasible chromophore polymer film materials, and implemented real-time dynamic autonomous activation or deactivation control of glass film coatings by using advanced photovoltaic induction technology, Design and manufacture a full-function intelligent window.

    In order to increase the area of lighting and ventilation or show the personality characteristics of modern buildings, the area of doors and windows of buildings is becoming larger and larger, and there are all glass curtain wall buildings, so that the heat loss of doors and windows accounts for more than 40% of the total heat loss of buildings. Energy saving of doors and windows is the key to building energy saving. Doors and windows are not only sensitive parts of energy source gains and losses, but also related to lighting, ventilation, sound insulation and facade modeling. This puts forward higher requirements for the energy saving of doors and windows. The energy-saving treatment is mainly to improve the thermal insulation performance of materials and the sealing performance of doors and windows.

    It is understood that the organic combination of various polymer film material coatings must be suitable for the film coating production and processing technology of window glass. At present, the film coating products are being monitored and verified for short, medium and long-term performance indicators, environmental protection standards, safety and reliability. The R & D team is also making efforts to reduce technology production costs and actively expand the application potential of smart window technology in the field of energy-saving buildings.

    Since the 1960s, fluorescent polymers have gradually become a research topic of keen concern because of their good mechanical properties, easy film formation and convenient processing. Pyrazoline chromophore is a high-quality luminescent material. Its emission wavelength is about 450 nm. It has high fluorescence quantum efficiency, narrow emission wavelength and good color purity. It is a pure blue light.
