Outline of Final Research Achievements

By spray coating the graphene/ graphene oxide flake, we prepared a filtration membrane for desalination and other separation. As a result, 85~96% desalination was achieved. It was found that not only the hole within the graphene, but also the edge space and interlayer space were crucial for the efficient atomic/ molecular separation.
Oxidation of cup-stacked carbon nanotube resulted in the expansion of the interlayer spacings and cleavage of the tube, which enabled us to make the most of the internal graphene edge. It was found that the surface area increased up to 400% of the untreated nanotube.
