A thin layer of graphene paint can make impermeable and
chemically resistant coatings which could be used for packaging to keep food
fresh for longer and protect metal structures against corrosion, new findings
from The University of Manchester show.
The surface of graphene, a one atom thick sheet of carbon,
can be randomly decorated with oxygen to create graphene oxide; a form of
graphene that could have a significant impact on the chemical, pharmaceutical
and electronic industries. Applied as paint, it could provide an ultra-strong,
non-corrosive coating for a wide range of industrial applications.
