Static light scattering studies of polymer colloids

Abstract

Static light scattering (SLS) has been used to study polymer monodisperse particles (Colloids). Dilute polymer particle of diameter 0.38 µm dilute colloidal system has been synthesized to avoid multiple scattering. Colloidal particles can form lattices according to DLVO theory, where they interact by Coulombic repulsion and Vander walls attractive force (DLVO Potential whenever the repulsive potential dominate the particles begins to interact strongly to form bcc, fcc or other lattice structures in the colloids. This is defined by structure factor S (Q) in a colloidal system. On the contrary, when attractive forces dominate in the colloids, the particles begin to form clusters. The present studies, however deals with dilute solution and therefore scattering take place from individual particle. This give rise to single particles scattering revealing morphology of particle. Static light scattering (SLS) can be affectively used as a technique for single particle scattering. The present study uses unpolarized light and polarized light (linear and circular) to study the effect of polarization over the single particle scattering event.Static light scattering (SLS) has been used to study polymer monodisperse particles (Colloids).
