Monte Carlo studies of optical transmission of anisotropic suspensions

Monte Carlo model for simulation of light transmission in anisotropic suspensions filled by absorbing cylindrical particles with anisotropic shape was developed. Aspect ratio of the cylinders (i.e., ratio of length and diameter) was varied between r = 0 (infinitely thin disks) and r -> infinity (infinitely thin rods). The cooperative filling model was used for simulation of clustering of particles controlled by aggregation parameter f Orientation ordering of particles in anisotropic suspension was characterized by order parameters S. The effective cross section of particles and deviations from the Beer-Lambert-Bouguer law were studied as function of r, f and S. Obtained data may be useful for understanding the experimental data on optical properties of media filled with carbon nanotubes. (C) 2018 Elsevier B.V. All rights reserved.
