N2 - Processing of nanocomposites strongly influences final material performance. This work investigates the dispersion of SWNT-epoxy composites processed by two different methods. Two sets of composite material with identical compositions were synthesized using an ionic liquid dispersant/initiator. One set of material was processed by rotational shear mixing, the other by three roll milling. The SWNT dispersion of resulting SWNT-epoxy composites was evaluated using SEM imaging, and electrical conductivity measurements in conjunction with percolation theory analysis. Critical percolation occurs at much lower volume fraction for samples prepared using three-roll milling which suggests the formation of a more uniformly dispersed system using this processing method.
