Abstract: A technique for computer simulation of a random 3D distribution of carbon nanotubes (CNTs) with different orientations in a polymer matrix and calculation of the distance between nearest neighboring CNTs is described. It is shown that at low volume concentrations of CNTs, with an increase in CNT ordering, the character of the distribution of the minimum distance between CNTs changes significantly (from exponential to logarithmically normal), and the average minimum distance between CNTs noticeably increases. The proposed method and calculation results can be used to simulate the electrical conductivity, thermal conductivity, and other physical properties of polymer nanocomposites.

Keywords: carbon nanotubes, orientation, computer modelling, random location, distance.
