Technology comes in all shapes and sizes and in the case of nanotechnology, extremely small sizes, as small as one billionth of a meter in fact. One example of nanotechnology being applied in the real world is through a new waterproofing science known as superhydrophobic coatings, and the industry leader in this field is Canadian company, Nanex. Nanex develops and sells their AquaShield waterproofing spray that doesn’t just protect against water and other water based fluids, it actually scares the water away using sub-molecular polymers called nano-polymers and the results are visually incredible.
Nanex demonstrates their superhydrophobic coating protecting materials of all types from water, wine, and even soda. They also demonstrate mud bouncing off of a cement wall coated in AquaShield without leaving a trace. On each surface whether its cotton or cement the superhydrophobic coating appears to be completely invisible and according to Nanex you can’t even feel that there’s a waterproof coating present. Although there are many superhydrophobic waterproofing sprays available, Nanex states that what sets theirs apart from the others is that level of transparency coupled with the eco-friendly, non-toxic status of the water repellent sprays. The AquaShield water repellent spray is almost entirely water, but that’s just the delivery agent.
What actually forms the superhydrophobic coating are the nano-polymers in the water. These enter into the material on a sub-molecular level where they cling to each individual fibre by the millions. They’ll stay there for up to two years creating a superhydrophobic surface out of what was once just a regular cotton shirt or leather shoes. Examples of nanotechnology have been present in science fiction for decades, but more recently we’ve begun to see it used in medicine and even in lithium batteries for electric cars and cell phones. Despite all the advancement and potential in just about every industry it looks like superhydrophobic coatings may be the first readily useable example of nanotechnology.
