Comparison of filler percolation and mechanical properties in graphene and carbon nanotubes filled epoxy nanocomposites

- We compare the percolation network of carbon nanotubes and graphene in epoxy nanocomposites.
- Carbon nanotubes readily form a percolated network characterized by high viscosity and high electrical conductivity.
- The low viscosity of the graphene dispersions let us double the maximum amount of carbon nanotubes.
- Graphene is the most effective reinforcing filler without compromising their processability.
