A simple, inexpensive spray method that deposits a graphene
film can heal manufacturing defects and produce a high-quality graphene layer
on a range of substrates, report researchers at the University of Illinois at
Chicago and Korea University.
Their study is available online in the journal Advanced
Functional Materials.
Graphene, a two-dimensional wonder-material composed of a
single layer of carbon atoms, is strong, transparent, and an excellent
conductor of electricity. It has potential in a wide range of applications,
such as reinforcing and lending electrical properties to plastics; creating
denser and faster integrated circuits; and building better touch screens.
