structure can basically produce the same thing once you fix the network somehow, which you may refer to as prestressed.

This suggests that it is extremely important to have a percolative
network consisting of only s-SWCNTs without metallic shorts to achieve high sensitivity.
He used percolative
theory and microcapacitor modeling to explain these results.

Further, it would be interesting to investigate the influence of the formation of the percolative
'network-like' structure formation of MWNTs in the respective PA6/ABS blends with unmodified and modified MWNTs through electrical conductivity measurements.
The variation in complex viscosity and the storage moduli values in the lower frequency range during the frequency sweep indicate the transition from 'liquid' to 'solid-like' behavior prominently, which is a consequence of a rheological percolative
'network-like' structure formation between the polymer and the filler.
At 5 wt% of MWCNT, the images give the impression of a percolative
morphology due to overlapping of the tubes.
(119) exploited the sodium salt of 6-aminohexanoic acid (Na-AHA), which was able to assist in debundling the MWNT through cation-[pi] interactions during melt-mixing leading to percolative
network-like structure of MWNT within the PA6 phase in co-continuous PA6/ABS blends.
This is due to the formation of a percolative
network, which resulted in maximum property enhancement.
However, there may be competing factor like reaggregation of nanotubes in the presence of excess modifier which may not induce better percolative
network of MWNT.
Several authors have found that the three main factors that contribute to the conductivity of composite polymers are (a) high-electrical conductivity of the used filler, (b) the relative spatial distribution of conductive filler (percolative
distribution), and (c) interparticle "contact" resistance that reflects the kinetics of charge-transfer across filler particles [18-20].
Such core-shell structured Al particles give their composite a high dielectric constant as a percolative
system owing to the metallic core but a low dielectric loss comparable to that of a neat epoxy resin due to the insulating alumina ceramic shell (2).
22 wt%), although the final resistivity after the formation of a percolative
path is about 104 [ohm] cm, lower than that of GN-filled HDPE nanocomposites (ca.
