Ion-Mask Coating Could Make Waterproofing Electronics Easy

Engadget is reporting that a new chemical coating, originally designed to repel toxic vapors and liquids from soldiers' uniforms, may be the solution to small waterproof electronics. "The Ion-Mask is a special invisible coating that is chemically bonded to the device and repels water. It should allow waterproofing to make it into devices that are too small for the seals that are usually used to do the trick. Devices can have joins and gaps coated for a general level of water repellence, or have individual components treated for even more protection."

Ponca City, We Love You writes "Researchers at Monash University, in Australia, have found a process to coat natural fibers such as wool, silk, and hemp that will automatically remove food, grime, and even red-wine stains by coating their fibers with titanium dioxide nanocrystals, which break down food and dirt in sunlight. Titanium dioxide is a strong photocatalyst and in the presence of ultraviolet light and water vapor, it forms hydroxyl radicals, which oxidize, or decompose, organic matter. "These nanocrystals cannot decompose wool and are harmless to skin," says organic chemist and nanomaterials researcher Walid Daoud. Titanium dioxide can also destroy pathogens such as bacteria in the presence of sunlight by breaking down the cell walls of the microorganisms making self-cleaning fabrics especially useful in hospitals and other medical settings."

      Not necessarily. Hairdryers generate heat by sending an electrical current through a filament to heat it up, but that filament directly accessible through the wide nozzle of the hair dryer. This ion-seal doesn't prevent electrical current from touching water, it merely prevents water from seeping through small holes or cracks in a device. With the wide nozzle of the hairdryer, water could still easily flow directly into the filament - which means you can still check to see if your buddies reaction speed is

    Considering that I just sent my iPod through a ride in the washing machine, this could be quite useful. Not only for waterproofing, but also for cleaning electronics. Sure you can send your keyboard through the dishwasher, but you still have to let it dry for quite a while. It'd be a nice way to clean more intricate electronics as well.

      What I really should be doing is stocking up on PS/2->USB connectors so I'm able to use it with the future USB-3 only motherboards.
        • I had that problem a while back (I have an expensive keyboard that I didn't want to repurchase just to get a USB version). I bought a bunch of different PS/2->USB and ended up buying a $70 converter that actually worked.

          Any idea why that is the case? Furthermore, what are those cheap converters for if they don't work for keyboards? Do they work for mice?

            As far as I am aware the cheap ones simply act as connection changers and allow for keyboard manufacturers to create PS2/USB keyboards with only one connection on the end. The keyboard has to decide to what port it is connected and uses the appropriate protocol. The expensive ones actually change the protocol between USB and PS2 so the device doesn't have to be USB aware.

          • If memory serves, it is due to the voltages required by the Model M - and the voltages that are put out on certain newer motherboards.

    I guess this could be nice in the "small device" application that they mention, but other bigger devices come to mind:

    - Ever ruin a laptop by spilling soda on it? It might still be sticky, but you wouldn't fry the motherboard.
    - Ever tried waterproofing an outdoor AP or camera? You have to be very aggressive -- this could make things easier.

    It would be great if this stuff came to market like a Rustoleum-type spray.

      I thought of this too, but it brings up some important things to consider first: 1. Will the treatment inhibit heat transfer? Does it even stand up under heat? The article was pretty vague on that point, but if the answer to the first one is yes, or the second one is no, then that would limit its functionality greatly when expanding it to uses outside those mentioned in the article, namely phones. 2. Cost. How much does it cost to do this? and, more importantly, would there be a way to do it yourself, or to bring something in somewhere and get it done for you? If the is prohibitive, then it also lowers the usefulness, but if its cheap, easy to use, and you don't have to have a contract with them to get it done... this could end up being a pretty nice addition to ANY portable electronics.

    Although this coating may make something waterproof, I'd doubt that it makes the device surfactant-resistant. Soapy water (in the shower, tub, sink, or washing machine) does not have the high surface tension or tendency to be repelled by hydrophobic substances that I'd bet this coating depends on.

    Of course, I could be wrong and would enjoy an informative post that proves that this coating can survive suds.

    This article elaborates on how it would work with shoes/clothing:

    "Rather than absorbing water and dirt, moisture will instead bead off the surface of the specially-designed shoes."

    And then another advantage (for insurance companies at least) is the insurance angle:

    "For electronic devices, protection from water is also important. Water damage is one of the top reasons for insurance claims on mobiles, with more than 1.2 million being dropped in lavatories, drinks or put through washing machines last year."
