Scientists from the Australian National University (ANU) have developed a new spray-on superhydrophobic coating that can make your electronics waterproof for life.
This innovation has been worked on specifically due to the wide variety of potential consumer and industrial applications that waterproofing has in the market today.
The need for the development of such a robust waterproofing application comes as a direct response to the limitations that current waterproofing technology suffers from.
In order to understand these limitations, one must first understand how waterproofing actually works. In traditional methods, hydrophobic materials get their abilities thanks to rough surfaces made up of tiny pillars.
These pillars, trap air between them, thus preventing any sort of liquid from getting a good grip, which in turn makes the material underneath, waterproof.
However, despite their smart functioning, these materials aren’t durable, since these structures can damaged and rendered useless through long term use.
This made the scientists decide, that if they wanted to make the waterproofing more robust, they needed to make the structures more robust too.
Towards this end, they developed a new material, that combines two plastics, Polymethyl Methacrylate and Polyurethane, to form a structure that is up to 60 times more durable than it’s competitors.
In addition to being more durable, the new coating can also resist damage from acids, UV light and solvents like cleaning alcohols, making it compatible with a variety of other products.
Thanks to all these advancements, the new coating can be considered as a one time treatment to make your electronics waterproof forever.
While it will still take some time to accurately test how long does forever last, but as far as current waterproofing tech is concerned, it is still a game changer that we should be looking forward to.
