Nano paint for bathroom

Thanks to a new titanium dioxide coating, the bathroom in the future will always be clean, without the need to clean hands.

The self-cleaning material is the product of the researchers from ARC Australia's Center for Materials Nanomaterials. According to Prof. Rose Amal, with this material, families and hospitals will not have to use surface cleaners as well as other chemicals .

Currently , tiny titanium dioxide particles, 20 nanometers in diameter, are used to cover outdoor surfaces, such as self-cleaning windows . They absorb ultraviolet light with wavelengths below 380nm.

This wavelength stimulates the electrons and makes the titanium dioxide particles more potent than the chlorine bleach. Thus, nanoparticles can kill bacteria, disintegrating organic matter from vehicle exhaust and plant into carbon dioxide and water.

Surfaces coated with nanoparticle titanium dioxide also have the ability to self-clean when there is water and the water does not condense into it.

However, titanium dioxide can only be activated by ultraviolet light with a wavelength of less than 380 nanometers, in the condition of sunlight, not other light sources. This means that up to now self-cleaning coatings have been used for outdoor surfaces only.

GS Amal and his team modified nanoparticles of titanium dioxide so they could absorb light at higher wavelengths, above 400 nanometers, in the visible spectrum. They also mix these particles with small amounts of iron or nitrogen.

Tests have shown that new coated glass can be activated by light to kill Escherichia coli. In addition, it decomposes volatile organic compounds.

This material can be covered with tiles, mirrors, glass and benches in bathrooms, hospitals. It is also very useful for outdoor surfaces.
