    "Treatment makes surfaces self-cleaning"

    I read this article, a few weeks ago


    Do anyone know more about this? Can it actually be applied to metal?

    i.e. car body, so I won't have to wash my car ever again:!!) , I'm just kidding, but wouldn't that be great.

    Actually that fenomena use hydrophylic characteristic of material. One material that exhibit that characteristics is titania. Water form a layer instead of droplet on a hydrophylic surface so the dust stuck in water layer and easily removed by water.
    I think we can use in metal, just coat it with titania.
