| dc.description | Electrical conductivity of 150–200 μm thick polysulfone films loaded with 0.05–0.75% w/w multiwall carbon
nanotubes was systematically investigated for two types of dispersion states, uniformly dispersed and agglomerated at the
micro-scale. The percolation threshold was found at 0.11% and 0.068% w/w for the uniformly dispersed and agglomerated
films, respectively. Overall, the conductivity of the films with agglomerated nanotubes was higher than that of the uniformly
dispersed ones, with marked differences of 2 to 4
orders of magnitude for carbon nanotubes loadings in the upper
vicinity of the percolation threshold (0.1–0.3% w/w). The increased conductivity of the agglomerated state is explained by
the increased nanotube-to-nanotube contact after the percolating network has formed, which facilitates electron transfer. | |
