In another awesome project inspired by nature, scientists developed a new type of nano coating that makes a surface stay wet or keep it completely dry, and it never needs to be cleaned. Researchers at the University of Sydney created this newly discovered material by using raspberry-shaped nanoparticles that mimic the surface structure of a rose. Depending on the arrangement of these bundled particles, the surface can either repel water or soak it up like a sponge, and one of its many applications includes using it in airplanes to keep airborne viruses at bay.
The newly discovered material is made with small clusters of charged nanoparticles that trap tiny water droplets, preventing them from rolling off surfaces even when turned upside down. At the same time, when the same structure of miniature bobbles is created with fluorinated polymers it provides a highly water-repellent surface.
Dr Andrew Telford, the lead researcher from the University’s School of Chemistry, says that their research could allow a person to design a flexible surface with multiple functions. “”We could also design a surface that stays dry forever,” Telford said in a release. “Never needs cleaning or able to repel bacteria or even prevent mold and fungi growth.”
Beyond making quick drying walls or other surfaces that never need to be cleaned, the raspberry nanoparticles could be utilized to reduce the condensation in airplane cabins, making them less hospitable to airborne viruses. Alternatively, the scientists are also looking into medical apparatus that can be safely used outside of labs or an operation room.
