Application of WO3 nanoparticles nanopowder: for thermal insulation glass
Nano-tungsten oxide is a new type of thermal insulation medium, or it can be said to be a new type of functional nano powder, which is often used to prepare glass thermal insulation coatings. The obtained transparent heat-insulating coatings are often used in sunrooms and other buildings that use large-area glass, and the effect of heat insulation and sun protection is remarkable, which is the development trend of the heat insulation industry in the future.
Tungsten trioxide is a semiconductor material. The band gap of the tungsten trioxide semiconductor is 2.6-2.8 eV, so it has a relatively short cut-off wavelength of about 460 nm. A large number of studies have shown that the surface plasmon resonance of semiconductor materials can absorb light of specific wavelengths. Performing certain reduction treatment on tungsten oxide nanoparticles or adding third-phase cations can accumulate a large number of free electrons on their surface, so that they have the characteristic of plasmon resonance absorption of near-infrared light. At the same time, since the size of nano tungsten trioxide particles is much smaller than the wavelength of visible light, it can maintain the transparency to visible light.
Coating nano-tungsten oxide glass heat-insulating paint on the glass surface of the sun room can form a coating heat-insulating layer with spectral selectivity, which can block sunlight from radiating indoors. In summer, it can effectively reduce the heat entering the room, insulate and sunscreen, reduce indoor temperature and air conditioning energy consumption, reduce hot sensation, and improve comfort; effectively block harmful ultraviolet rays, protect human skin from harm, and slow down the aging of furniture and other interiors. Extend service life; no shielding of electronic signals, no edges, no bubbles, environmental protection and durability.
