Conference paper


The MesoDyn simulation code supplemented with the percolation and cluster analysis concepts has been used to generate the subcritical percolating networks of PEDT beads of the coarse-grained PEDT/PSS complex in a range of PEDT/PSS mass ratio up to 20. Based on the comparison of the percolation parameters in three perpendicular directions, the anisotropy of the networks has been determined and its correlation with the macroscopic electrical conductivity has been evaluated.
