Paper Abstract

In the paper, direct current conductivity of percolation channels in composite cellulose - insulating oil - water nanodrops, was analyzed. Number of nanodrops in macroscopic length channel (on the order of a few millimeters) is about 106. In such nanocomposites below the percolation threshold, direct current conduction takes place by electron tunneling between the potential wells generated by the nanoparticles of the conducting phase. On the basis of the tunneling mechanism, percolation channel resistance was calculated in which the nanoparticles are randomly distributed. Gauss probability distribution of the distances between neighboring nanodrops was used for the calculations. The standard deviation of the average distance between neighboring nanodrops was chosen as the disorder factor. It was established that the percolation channel resistance value is lowest in the case of regular distribution of the nanodrops. With the increase in disorder, which is characterized by an increase in the standard deviation value, the resistance of the percolation channel increases.
