Abstract
This present invention relates to a method of preparing graphene-based film, said method comprising: providing a first graphene-based film comprising sheets of graphene, graphene oxide, partially reduced graphene oxide, reduced graphene oxide, or a combination of two or more thereof, that are (i) arranged relative to each other in a substantially planar manner so as to form a layered structure, and (ii) at least partially separated by a liquid medium; exchanging said liquid medium with a packing density adjustment medium that comprises at least two components, wherein one of said components has a volatility greater than the other component; and removing at least some of the more volatile component from the first graphene-based film to produce a graphene-based film that has a different packing density of the graphene-based sheets relative to that of the first graphene-based film.
