A team of researchers from The Australian National University (ANU) has created a new spray-on protective coating with a remarkable ability to repel water that may be used to waterproof smartphones, and is also cheap and UV resistant.

"The surface is a layer of nanoparticles, which water slides off as if it is on a hot barbecue," said PhD student William Wong from The Australian National University (ANU). 

The team created a much more robust coating than previous materials by combining two plastics, one tough and one flexible. 

"It's like two interwoven fishing nets, made of different materials," Wong said. 

The water-repellent or super hydrophobic coating is also transparent and extremely resistant to ultraviolet radiation. 

Lead researcher and Associate Professor Antonio Tricoli said the new material could change how we interact with liquids. 

"It will keep skyscraper windows clean and prevent the mirror in the bathroom from fogging up," Tricoli said.

"The key innovation is that this transparent coating is able to stabilise very fragile nanomaterials resulting in ultra-durable nanotextures with numerous real-world applications," said Tricoli. 

The team developed two ways of creating the material, both of which are cheaper and easier than current manufacturing processes. 

One method uses a flame to generate the nanoparticle constituents of the material. For lower temperature applications, the team dissolved the two components in a sprayable form. 

In addition to waterproofing, the new ability to control the properties of materials could be applied to a wide range of other coatings, said Wong. 

"A lot of the functional coatings today are very weak, but we will be able to apply the same principles to make robust coatings that are, for example, anti-corrosive, self-cleaning or oil-repellent," he said.
