Complex electric conductivity

Using linear response theory and noting (according to the results at the end of Section 5.1.3) that the (complex) electrical conductivity a is the Fourier transform of the current density autocorrelation function, we obtain from Eqn. (5.75) (see the equivalent Eqn. (5.21))... 

Although the anisotropy of the complexes electrical conductivity was not mentioned, the three-dimensional nature of the complex facilitates a metal-like temperature dependence of its conductivity down to 4K where a = 105 2 lcm l (room-temperature a is a respectable 300 2 1cm 1). The absence of a metal-insulator transition down to 4K shows that the Peierls instability has been successfully avoided by increasing the interstack coupling. 

The mixture theories were originally developed for dielectric properties, but can be applied to other properties that are governed on a macroscopic level by Laplace s equation ( 10). Consequently, the generalized conductivity in the above equations can be the ionic conductivity o, thermal conductivity K, or complex electrical conductivity o defined by ...

For composites obtained from LCF (long carbon fibers)/PP matrix/PANl (polyaniline complex), electrical conductivity was much higher and surface resistivity much lower that in the case of separate LCF/PP and PP/PANI complex composites. By using the PANI complex, the percolation threshold of LCF composites could be moved towards a reduced fiber content. Electrical conductivity measurements over the thickness of the sample and in different directions showed a synergetic effect [136].
