To disperse exfoliated graphene in an organic solvent, it is necessary to use dispersants with a strong affinity to the carbon surface.
Four types of interactions with the surface of carbon nanostructures are possible:
- Pi-pi interaction
- Chemical boundings
- Van de Valls forces interactions
- Electrostatic interactions
Which of them would be the best for the easiest electron transfer from one surface of a graphene flake (mainly multi-layer in the case of exfoliated graphene) to another?
The structure of the emulsifier itself should also facilitate this transfer.
The goal is to produce an epoxy resin composite with exfoliated graphene with the best electrical conductivity.
I would like to start a discussion on the influence of dispersants on the electrical conductivity of composites filled with exfoliated graphene.
I will be grateful for any opinions and comments.
