Nanotech Paints For Military 370

pmacwill wrote to us with a recent article on Pennet in regards to the U.S. military's proposed use of nanotech paints. Actually, it goes beyond proposal -- and beyond paint, as it would allow vehicles to change camo patterns very easily, and would also repair micro-cracks and fractures without the need for service.

    Army researchers eye nanomachine-based 'smart' paints for combat vehicles

    by John Keller

    PICATINNY ARSENAL, N.J. -- U.S. Army experts are trying to embed microscopic electromechanical machines in paint that could detect and heal cracks and corrosion in the bodies of combat vehicles, as well as give vehicles the chameleon-like quality of rapidly altering camouflage to blend in with changing operating environments.

    Officials of the Army Tank-automotive and Armaments Command's Armament Research, Development and Engineering Center (TACOM-ARDEC) at Picatinny Arsenal, N.J., are working with scientists at the New Jersey Institute of Technology in Newark, N.J., to develop nanotechnology-based "smart" coatings for Army vehicles and other materiel.

    Unlike today's paint coatings on battlefield vehicles, Army experts seek to develop paints with the ability to self-correct because of changing circumstances and tell the user of potential anomalies such as corrosion or adhesion problems.

    Today's conventional paints are labor intensive to apply, and potentially hazardous to the people working with them, Army officials say. In addition, most of these coatings need to be touched-up by hand, which can hide damage to the metal or other substrate material.

    As a result, Army leaders estimate the total cost for U.S. Department of Defense corrosion-related problems at $10 billion per year -- $2 billion of which is related to painting and paint-scraping operations.

    To rectify these problems experts from Picatinny and the New Jersey Institute of Technology plan to develop a prototype paint with nanomachine powders consisting of tiny machines that act as gears, motors, and electronic switches at the atomic level.

    These "smart" paints should be able to alert maintenance technicians of potential problems with the coating, in addition to modifying their physical characteristics on command.

    These future "smart" coatings will involve far more, however, than simply brushing on paint from a can, points out Joe Agento, program integration manager at the TACOM-ARDEC Industrial Ecology Center at Picatinny Arsenal.

    "Rather than paints, we are talking about coatings, which could be electroplated, or put on with physical vapor deposition qualities. We are talking about more things than paints. They could be metallic or have other qualities," Agento says.

    "We're trying to prototype a coating to replace the primers and top coats we use today, and develop a one-system coating that incorporates nanomachines within the coating itself," says Laura Battista, environmental engineer at the Industrial Ecology Center.

    "Now we are looking at the first stage -- a coating with nanomachines," Battista says. "We want to determine what the nanomachines are that we need; we still have to determine what that nanomachine would be -- switches, motors, or gears -- to allow the coating to change on command."

    Vehicle operators might quickly change the camouflage paint scheme on vehicles with "smart" coatings with an electrical impulse, Battista explains. "What we hope this coating can do is amazing. We're also looking at making it seem invisible."

    Researchers will begin by determining what the properties of a "smart" coating would be. Later, researchers would develop a prototype, before applying the coating to a tank or other Army vehicle, Battista says.

    A prototype "smart" coating may be developed as early as 2005, she says. "Once you already have the properties of the coating, such as the camouflage properties, we hope that changing the camouflage is as simple as changing pixels in the coating; it shouldn't be that difficult," she says.

    Assuming that researchers receive the necessary funding, Battista speculates that "smart" coatings might be deployed with active combat forces sometime between 2005 and 2009.

      I'm always unimpressed with this sort of "news". Of course what they hope it can do is amazing! And a lot of things "may" happen as early as 2005. But is there anything that indicates that they're making real progress? This is like a not-very-detailed grant proposal, in press release form.

Granted, it would be nice for HQ to be able to issue one command as a convoy moved from grass to sand (or a similar situation) but the potential for disaster would be unbelievable. A simple human control selected by the driver should be far more effective.

Perhaps nanotech could operate like insecticide, and get on the enemies' clothes, and send signals when the soldier returns back to base. At that time, a larger cloud could be enabled that would paralyze the forces, and they could be held as POW until the conflict ended.

    Another toy for the military to spend millions of dollars on while people remain unemployed, homeless, or just plain poor here.

  • This is what happens when you increase defense spending by a huge amount - they don't know what to do with it, so at that point, crazy little applications like smart paint start getting approved.
    How about worrying about improving the 50% chance that the National Missile Defense program has of intercepting an incoming nuke? And even THAT's assuming that the missile follows a plain vanilla trajectory with no fancy moves.

    Actually, it goes beyond proposal -- and beyond paint, as it would allow vehicles to change camo patterns very easily

    As a result, Army leaders estimate the total cost for U.S. Department of Defense corrosion-related problems at $10 billion per year -- $2 billion of which is related to painting and paint-scraping operations.

    Could this possibly be true or just a hyper-inflated figure to help sell/make the idea of bleeding-edge tech coatings seem realistic and feasible?

    I mean, come on... $2 billion a year just for painting and paint removal? What are they doing? Hiring only the most intelligent and beautiful virginal labourers to paint tanks with paint made from elements only found in asteroids, using fine, #10 ultra-sable brushes, gently scraping paint off with custom made, solid gold, diamond tipped scrapers?

    There have been rumors milling around that during WWII the US military was playing around with under-wing/fuselage lighting to camoflage bombers during daytime. It was considered useless at the time, but recently (I think the 80's?) there was a project that combined lighting with photoreceptors (CCD's maybe) where they were able to make a drone virtually invisible above a certain altitude. Rumor is it was classified after a few tests. Anyone heard anything like this?

    A long time ago (1986 or so) I worked for a summer at the Night Vision Electro-optics lab at Ft. Belvoir, Maryland. The topic of study was infrared camouflage.

    Visual camouflage works by fooling your eye into thinking the object is part of the background. This is done by breaking up profile, matching background colors, and various other tricks.

    The same problem exists in the infrared, except you have the additional wrinkle of controlling IR emission (just like carrying around a flashlight blows visual camouflage).

    IR happens to be a useful wavelength for detection, because it readily propagates through the atmosphere without loss (over 99% transmission, with exception of two frequencies near 2500 and 25000 where water absorbs and another absorbion band for CO2), and because most objects radiate it (e.g., people, sunlight on the hood of a vehicle, engines, leading edges on wingtips. etc.).

    In the 2500 - 25000 nanometer range, to match up with the forested/vegetation background in Maryland, we needed to duplicate the chlorophyl curve, which is the dominant background emission spectra. And, pretty much, they were able to do so, with some expensive nets and other mechanisms. They were trying for an integrated visual/IR/radar camouflage system (the radar folks worked in the same lab).

    It's very interesting to read about these paints, since this appears to be the first reasonably viable mechanism for achieving this. They would need a chlorophyl pattern for vegetated regions, a desert pattern for deserts, etc. They would also still need to baffle and reduce IR exhaust, since paint won't help camouflage heated air or hot gun barrels.

    The mechanisms previewed so far in the literature (electromechanical gears, electroptical properties) wouldn't likely generate much signature, if any. However, there might be some operation characteristic (e.g., power on) that could be detected with a SQUID (superconducting quantum interference device). However, the SQUID would pick up the spark plugs in the tank long before the electronic signals to the paint.

    Prototype by 2005? I doubt that. They admit to not even knowing what types of nanotech "gears and switches" they are going to need, let alone how to hook it all up to make the paint do what they want. How will they address individual pixels? How will they power it? Nanotech isn't magic, folks. As far as the military already having this technology, I doubt that too. Creating a coating with radar absorbing qualities is one thing, creating one that thinks and moves in a combat environment is entirely different.

    Sounds like they've been smoking that "gotta spend our increased budget or lose it" crack.

    One way to make color changing paint would be to create a grid of fins that could be moved closer together or farther apart. A butterflies wings are colored not with pigments, but with particles that have a gap sized to create interference cancelling out all but a specific wavelength of light. By adjusting the gap, maybe mechanically, maybe electrically, you could adjust the color.

    Another way would be balls, with say 6 different spots of color on different sides. Rotate the ball to get different colors.

    Another way would be pigment sacks, like a cuttlefish uses.

    Now try to think about how to address all the pixels on, say, a tank, with any of those systems. Then think about how you would go about making a system like that self-repairing.

    I would bet that by 2005 they have a prototype that looks bad, changes color slowly, fades quickly in sunlight, breaks down often, and doesn't self repair. They may have a working color changing paint by 2009, but I doubt they will get the self repairing bit down that soon.

    Just thought about it a bit more. They may develop a self repairing undercoating which could fix small cracks in the metal or undercoating by reacting to oxidation and releasing a sealer or catalyst that would bond paint or metal It's making the color changing bit itself self repairing that sounds hard to me.

    Imagine connecting the nontech-based paint job to the vehicle's speedometer. As the vehicle moves, the camo pattern could scroll at the same speed in the opposite direction. In the proper environment, this could make the vehicle difficult to spot when moving, since the observer's eyes would be presented with data not normally present in nature.

      Screw that, make my car jet black and as i speed up, make all the leading edges start to glow like an SR71 plane (or shuttle on re-entry).....

      How cool would that be????
