percolation limit

percolation limit

[pər·kə′lā·shən ‚lim·ət]
(solid-state physics)
In a disordered crystalline alloy having one constituent with a magnetic moment, the concentration of the magnetic element above which the spin-glass phase is replaced by the ferromagnetic state.

The resistivity of the composite continues to follow this power law until a percolation limit is reached.
5 volume percent, and a percolation limit generally at 10-20 vol%.
Values for the percolation threshold, limit, and electrical conductivities at the percolation limit are given in Table 2.
While the basic power law does capture differences in the percolation threshold, it cannot distinguish between differences in the percolation limit across polymers, nor does it lie within the proper region of actual conductivity behaviors.
However, measured resistivities for the unfilled polymers reveal that the electrical resistivity of the polymer does not regularly correlate to either the percolation threshold or percolation limit for available data.
This is explained by the fact that it exceeds the percolation limit and results an increase of interactions number between carbon nanotubes.
