Graphene and CNMs: A comparison

We are often asked about the difference between graphene and our carbon nanomembranes. The simple answer is: Graphene is atomically thin graphite, a CNM is a molecular thin plastic film.

The following table shows the differences in a more comprehensive manner:

CNM Graphene
A CNM is a molecular thin polymer-like membrane. Graphene is atomically thin graphite.
CNMs have a homogeneous thickness of one molecular monolayer due to their manufacturing process. The thickness and homogeneity of graphene depend on the manufacturing conditions.
CNMs are elastic and follow the morphology of a substrate. (Technical) Graphene is brittle.
CNMs can be easily chemically functionalised. Graphene cannot be easily functionalized and loses its properties during the process.
Perforation can be intrinsically achieved during fabrication. Perforation has to be performed retro-actively (e.g. via UV/ozone etching or ion bombardment).
CNMs are electrically insulating. Graphene has a unique electronical structure.
CNMs can be transformed into graphene. Graphene cannot be transformed into CNMs.
