“…The appearance of a plateau means that an increase in the filler concentration in this range may lead to the emergence of new conductive chains, but these chains may be longer, which is the reason for the insignificant contribution of these newly formed clusters to the reduction of resistance. Furthermore, an increase in the concentration in this range of values may lead to a certain reduction (optimization) of the lengths of the already existing conducting circuits-clusters [11,15,16].…”

“…In order to obtain the values of the electrical resistivity of the fibers, the current-voltage characteristics (CVC) of the composites were measured using an automated CVC measurement system based on a Keithley 6487 picoammeter and an AKIP-1124 programmable DC power supply. To improve the contact between the sample and the electrodes, we used Conductive Carbon Paint (SPI) [12,15]. Volumetric electrical resistance was calculated by the formula:…”

“…It has been experimentally shown that the conductivity of composite fibers depends on a whole set of factors: the polymer matrix, the type of filler, its geometry and concentration, the degree of fiber drawing, manufacturing technology, etc. [15,16].…”

Polypropylene and polylactide-based composite fibers have been produced by a melt technology. Long vapor-grown carbon fibers (CNFs) have been used as electrical conductivity fillers. It is clearly shown by experimental methods that the CNFs are evenly distributed in the polymer matrix, orienting themselves along the direction of fiber extrusion and retaining their initial dimensions. It is shown that for composites fibers based on crystallizing (polypropylene) and amorphous (polylactide acid) polymer matrix, the dependence of electrical resistance on the filler concentration is percolation character and can be described as a double Boltzmann function. Four sections are identified on the dependences of the electrical resistance on the filler concentration for composite fibers, and the reasons for this character of this dependence on the formation of electrically conductive circuits are analyzed. Investigated in this work are the PP-based and PLA-based composites filled with carbon nanofibers that can be used as antistatic, shielding materials, or as sensors.

“…1 c). The manufacturing process, described in [1][2][3], of the filled polymer took place according to the melt technology. Filler concentration (K) was 0 wt.%, 10 wt.%, 20 wt.%, 30 wt.% and 40 wt.% for CB; for CNF -0 wt.%, 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.%; for CNTs -0 wt.%, 3 wt.%, 6 wt.% and 10 wt.%.…”

“…In [1][2][3], it was experimentally proved that the concentration dependences of the electrical resistance of polypropylene filled with carbon nanofillers on the type of filler are percolative, which means that in a small range of changes in the concentration of the filler, a change in electrical resistance by several orders of magnitude is observed. The most important characteristics of this process are:…”
