Abstract

In this paper the estimation of sphere size distributions of polymer latex with static light scattering is investigated. For the calculation of the scattering data a model is proposed which describes a SOFICA-type goniometer that was used for the light scattering experiments. From the comparison of this model with a model that is based on Mie's Theory only, conclusions about the reliability of the estimation of size distributions from uni- and bimodal colloidal suspensions with static light scattering could be drawn. Furthermore, the contribution of multiple scattering was investigated, and a method is suggested which further improves the obtained results. Both simulated and experimental data were examined. For data analysis, a method based on Tikhonov regularization was used.

      Upon obtaining the particle size distribution, the optical cross sections were calculated using a MATLAB script (Supporting Information). The underlying equations for the optical cross sections from the Mie analytical solution for spherical nanoparticles are well-known and are documented elsewhere. [36,42] For each set of wavelengths, corresponding complex optical constants of Ag and refractive index of the medium (n = 1.33 for water), the extinction, absorption and scattering cross sections were computed for the entire particle population normally distributed about the mean size as shown in Fig. S1.

      Light scattering is a versatile and non-invasive set of technique for measuring in situ on PSD. With the development of multiangle light scattering (MALS) measuring systems [1–3], multiangle dynamic light scattering (MDLS) and multiangle static light scattering (MSLS) [4–6] are widely applied to measure PSD of a variety of systems like emulsions, polymers, vesicles. For the determination of nano- or submicron particle size, MDLS should provide a better estimate of PSD than MSLS, which focuses on the determination of PSD in the larger size range from roughly 0.1 to a few micrometers.
