Extensional flow and electric conductivity of carbon nanotube dispersed system were investigated. Single-walled and multi-walled carbon nanotubes were dispersed into a photopolymer. The SWCNT systems indicated higher extensional viscosity than the MWCNT systems. The break-up surface of the solidified stretching filament was observed using a scanning electron microscope. The SWCNTs protruded from break-up surface were partially aggregated outside the polymer. By contrast, the MWCNTs indicated more uniform alignment due to their stiffness. The SWCNT dispersed system showed lower volume resistance than the MWCNT system. The electric resistance was decreased remarkably by the solidification of photopolymer, and was decreased also by the extensional flow.
