脚趾头碎了可以愈合吗 新型材料有修复功能 碎屏能自动愈合

新型材料有修复功能 碎屏能自动愈合  

A new self-repairing material has been developed by researchers in the UK and they say it’ll be ready to integrate into everything from smartphone screens to nail varnish within the next five years。
Originally developed for aeroplane wings
the technology has the potential to revolutionise a range of industries with the capacity to move into tiny cracks and harden inside like the way blood forms a dry
protective scab to heal flesh wounds。
Made from a mixture of different carbon-based chemicals
this new healing agent produces a sheet of millions of microscopic spheres. When a crack breaks these hollow microspheres apart
a liquid is released that moves into the newly formed gap. A chemical reaction then causes the polymerisation - or hardening - of this liquid
causing it to glue to the edges of the cracks and form a hard
near-invisible filler。
这种新型治愈体由不同碳基化工品混合而成，会生成一张由数百万微观球体构成的板面。当裂缝打碎了空心球体的表面，它会释放一种液体填补到新的裂缝中去。随后的化学反应生成聚合作用，将液体硬化，使之将裂缝边缘沾到一起，形成几乎看不见的坚硬填充物。
The technology has been developed by a team from England’s University of Bristol
led by chemist Duncan Wass
and was presented at a Royal Society meeting in London last month。
"We took inspiration from the human body
" Wass told Chris Green at The Independent。
"We’ve not evolved to withstand any damage - if we were like that we’d have a skin as thick as a rhinoceros - but if we do get damaged
we bleed
and it scabs and heals. We just put that same sort of function into a synthetic material: let’s have something that can heal itself."
