Full-day self-cleaning smart window film
|
Ultrathin multifunctional films coated on glass and other substrates that comprise two-dimensional (2D) tungstate oxide nanosheets (TON) as building blocks. Surfaces coated in this material prevent fogging, are self-cleaning, block UV radiation and heat IR sources, whilst maintaining transparency to visible light.
- Ultrathin and transparent coating
- Self-cleaning and anti-fogging
- UV-responsive and thermally-insulated
- Photocatalytic with memory activity
- Coating on car mirrors to avoid fogging in winter time;
- Coating on external surface of building windows to block heat and achieve self-cleaning;
- Coating on internal surface of building windows for indoor air purification;
- Coating on glasses to block UV light.
Tungstate oxide, a semiconductor, is exfoliated into atomically-thin 2D nanosheets. A low-cost layer-by-layer (LBL) method is then used to generate the ultrathin films, whereby the monolayered tungstate nanodots act as building blocks. The nanodots possess unique properties including super-hydrophilicity and excellent electron storage and discharging ability, which results in multiple new functions
