New Take on Self-Healing Polymer Could Mean Scratch-Free Screens

techprophet writes to mention that a new take on self-healing plastic could provide a long-term solution to scratched screens. The new polymer, developed by scientists at the University of Southern Mississippi, uses UV light to reform bonds between molecules rather than embedded healing agents of similar systems. "At the core of their design is polyurethane, which is an elastic polymer that already has decent scratch resistance. To enhance its ability to withstand mechanical damage, Ghosh and Urban added two more components, OXE and CHI. OXE has an unstable chemical structure (a four-membered ring containing three carbons and one oxygen) that makes it prone to being split open. CHI is UV sensitive. The idea is that, if the polyurethane gets damaged by a scratch, the unstable ring structure of OXE will open to create two reactive ends. Then, UV light can trigger CHI to form new links with the reactive ends of OXE and thereby fix the break in the polymer."

    it could trigger a healing process, or it could release noxious fumes, killing the user.

    it's like a 70-30 chance, don't worry about it.

      *General surgeon warning: scratching the surface might result in death. Other less serious side effects may include "lung quake, facial corkboarding, eye-arrea, bearded thalamus, transsexual kidneys, rectal dyslexia, Flu-nami, Spontaneous Mertail, and Honey Nut Areolas".

      I've had rectal dyslexia and it was a bitch. However, the Honey Nut Areolas were quite enjoyable.

    i also submitted this story this morning so since this made it i guess mine will be scrapped. because of this i can also give you a few links. This is great technology no doubt.

    Sorry if i am a little excited but its nice to be personally linked to a university that is about 15 minutes from where you live.

      Huh? This is Slashdot. Why do you assume it will be scrapped? Give it a few more hours.

    Does anyone else think this technology could also serve well as self healing lenses for glasses?

    What good is a scratch free screen if I can't see it through my scuffed eye-wear?

    They still won't know love. If movies have taught us anything. That is the only weakness they need.

    If something is so important that you feel the need to post it on the internet... It probably isn't that important.

    Seeing as the scratches the technology currently fixes are only a few micrometres in size, it's probably more an issue of it being extremely difficult to place another scratch at exactly the same place as a previously healed one.
