The most important result is that the 99% semiconductor-enriched devices exhibit a much higher sensitivity compared to the 90% enriched device, suggesting that a few m-SWCNTs in a network can drastically weaken the sensing effect, even for high enrichment, and a percolative network consisting of only s-SWCNTs without metallic shorts is required to achieve high performance.
Hence, it can be commented that the MWNTs are accommodated in the elongated droplets and further in a well-developed 'co-continuous' phase, which results in a percolative 'network-like' structure formation of MWNTs [Table 1].
As the nanotube loading increased, the randomly distributed carbon nanotubes came closer (in other words, decrease in path length for charge carriers between nanotubes occurred) and even in the thin cut samples representing only a two-dimensional view of the three-dimensional structure, a percolative network structure became quite evident (Fig.
The migration of TRG during the phase separation led to an increase in local concentrations, which further assisted in the formation of a percolative network-like structure in the PaMSAN phase, shown by the time dependence DC conductivity in Fig.
This indicates that, once percolative network is formed, there is not much effect on the transition behavior from a liquid-like to a solid-like behavior.
The aggregation of CNFs can form a local conductive network which may initiate percolative conduction of the polymer composites.
As evident from TEM micrographs crosslinking already exists between the PANI chains due to gel formation and Ag nanoparticles do not produce any additional percolative network making only a small contribution to the overall conductivity due to band gap decrease of the nanocomposites.
Both 70/30 and 80/20 blends exhibit a frequency independent plateau over the entire measured frequency range indicating the formation of percolative network like structure of the filler.
The insulator-conductor transition due to the addition of filler (graphite) was found to be percolative in nature.
A gradual resistivity drop, rather than a sharp percolative insulator-conductor transition, characterizes the TPU/CB system, as opposed to a sharp percolative behavior observed for non-polar matrices (13).
The gas transport in a partially crystalline polymer presents two main features: 1) The absence of a percolative threshold.
