    Scientists develop self healing polymer glass

    Discovered by accident by Japanese scientists, the glass heals at room temperature (video).

    Re: Scientists develop self healing polymer glass

    I wonder what happens if you put two pieces on top of each other - or if the molecular bonding process that the surfaces need to be in very close contact (is in the line of a fracture.

    Shame it can't 'heal' that air bubble at the fracture line, and I'm no expert when it comes to patents but wasn't this invented in 1975?

    Seems a great idea but both above posts are valid. Also my screen has a crack in it and the above demo videos all show that the crack is still visible

    Video has comments disabled is suspicious. Cut in the video between bond and weight test suspicious. Would like to see a breaking point test of the material strength before and after joining

    Re: Scientists develop self healing polymer glass

    Why would anyone need space glass as a safety feature when you can have an 8K exterior camera and a video wall? Not to let in sunshine as it would just blind you anyway.

    Might be useful for something like car windscreens if they can get it clear enough.

    err, can you point out where in that lovely load of chemistry speak it talks about self-healing glass?

    ditto. And is it me or can you still see the line of fracture?

    It doesn't as the substance in the article is not glass, it's an epoxy resin/polymer called polyether-thioureas.

    doubt it - to make an engineering grade toughened glass that similarly fragemented into regular sized pieces and also self healed would be some feat, and I doubt this is near that sort of performance.

    It's the same polymer, but they make no mention of the self-healing properties

    Laminate it? It might even not need to be treated, depending on how sharp the typical shards are

    possibly, but it might not be allowed. I thought they went for toughened glass because you could smash it and get out, and in a crash it stopped the whole windshield popping out and acting like a battering ram. Plus it avoided the glass-collar decapitations that annealed glass shields used to create. Not a nice way to go. How laminate would fit into all that and compliance with the relevant crash regs I just don't know.
