I don’t know if I am expecting too much or not. Rice U. just
announced that they can produce one atom thick sheets of graphite
(graphene). Given this era of nanotechnology, why not one lattice
thick sheets of any mineral?
Graphite/graphene is very interesting in that it makes incredibly
strong sheets that don’t have significant attraction to each other
or anything else. This is in part why it is such a good lubricant.
Recently researchers found that a good, practical, consistent way to
separate graphite into graphene was to use regular tape.
By taking a small amount of graphite, putting it on some tape,
folding the tape over onto itself, and the repeatedly sticking and
unsticking the tape. The sheets of graphene are easily pulled away
from each other leaving individual layers.
This type of easy separation is very unusual, and the consistency of
a unilayered substance will be very difficult to match in any
substance that prefers to make 3-dimensional bonds, like minerals.
