A University of Michigan researcher has created a coating that could be used to repel water, oil, and other substances:

In an advance that could grime-proof phone screens, countertops, camera lenses and countless other everyday items, a materials science researcher at the University of Michigan has demonstrated a smooth, durable, clear coating that swiftly sheds water, oils, alcohols and, yes, peanut butter.

Called "omniphobic" in materials science parlance, the new coating repels just about every known liquid. It's the latest in a series of breakthrough coatings from the lab of Anish Tuteja, U-M associate professor of materials science and engineering. The team's earlier efforts produced durable coatings that repelled ice and water, and a more fragile omniphobic coating. The new omniphobic coating is the first that's durable and clear. Easily applied to virtually any surface, it's detailed in a paper published in ACS Applied Materials & Interfaces.

Tuteja envisions the new coating as a way to prevent surfaces from getting grimy, both in home and industry. It could work on computer displays, tables, floors and walls, for example.

[...] Ultimately, the team discovered that a mix of fluorinated polyurethane and a specialized fluid-repellent molecule called F-POSS would do the job. Their recipe forms a mixture that can be sprayed, brushed, dipped or spin-coated onto a wide variety of surfaces, where it binds tightly. While the surface can be scratched by a sharp object, it's durable in everyday use. And its extremely precise level of phase separation makes it optically clear.

Just what I needed for my keyboard, VR headset, countertop, toilet bowl, 1 gallon mayonnaise jar, t-shirts, patio deck, sailing ship, the inside of all of my body's cells, and synthetic killer bacteria.

    The coating could also be used in refrigeration, power generation and oil refining -- all industries that depend on the condensation of liquids. The new coating could enable equipment to slough off condensed water and chemicals more quickly, increasing efficiency by up to 20 percent. That's a game changer, as those industries are some of the world's most high-volume and energy-intensive.

    Sounds like Teflon, another fluorinated plastic. Teflon (Polytetrafluoroethylene ) is plenty slippery but fairly soft. Teflon is also relatively expensive compared to other plastics. I wonder what this new stuff will cost when used in volume manufacturing? And fluorine is not the best stuff to work with, will there be environmental problems?

      They want to give it to our kids right away!

      The research team is also doing further studies to ensure that the coating is nontoxic for use in places like daycare centers. Tuteja estimates that the coating could go to market within the next two years, and he believes childproof coatings are just the beginning.

        Rush it to market because the cost of keeping kid-stuff clean might bankrupt the country?

      2040 : Despite the denials by US industry lobbyists, there is growing evidence from independent researchers that the miracle coating can be linked to many forms of cancer.

      Just kidding ... about 2040 and the existence of independent researchers. Or US industry. Or US. Pick your fate, and enjoy your sure-to-be-found-toxic miracle.

    I wonder how durable this is in marine environments, what the friction coefficient is, and how toxic?

      Ideally it would be durable enough in marine environments, that we will never be able to get it out of the ocean. And never be able to get it off plants that are vital food for various organisms.

      If you had a truly Omniphobic "coating", that won't stick to anything, then how does it "stick" to the object you are coating?

      Not to worry. Those dirty hippie homosexuals you speak of will develop an omniphobic lube. Then straight people will discover this product. It will be discovered by alien archeologists that this use turned out to be the primary application of this new technology just before the sudden decline of humanity.

      We had those in the 60s. When I was in college. Let me tell you, they're much thicker than the disposable. Not as fun. But much safer. And if you washed them, they were cheaper. I could afford disposables. But sometimes I went with the washables, depending on the girl. The girls that were on the Pill were very popular!
