Estimation of single-walled carbon nanotube concentration in polyethylene using the spectral correlation method

The intensity distributions of scattered coherent radiation are studied using polyethylene films filled with single-walled carbon nanotubes. The use of a spectral-correlation method for analyzing the intensity distributions over various wavelengths make it possible to establish the relationship between certain parameters of the cross-correlation function of the distributions and the nanofiller concentration. The possibility in principle of a remote nondestructive measurement of the nanofiller concentration is demonstrated.
