Integral estimation of nanoparticles aggregation is solutions using intensity autocorrelation functions of the scattered light
https://doi.org/10.32446/0368-1025it.2018-13-16
Abstract
The method is proposed for studying the aggregation of nanoparticles in colloidal solutions, based on the estimation of the slowing-down of the rotational diffusion coefficients of nanoparticles, which are more sensitive to changes in particle size than their hydrodynamic radius, depending on translational diffusion. The possibility of a comparative evaluation of these changes and the calculation of the relative aggregation index from the integral values of the autocorrelation functions of depolarized dynamic light scattering is shown. The results of numerical simulation of the proposed method and its experimental approbation are compared.
