Graphene vs 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. |
