Microscopic theory of gelation and elasticity in polymer–particle suspensions

Abstract: A simplified mode-coupling theory (MCT) of ergodic-nonergodic transitions, in conjunction with an accurate two-component polymer reference interaction site model (PRISM) theory for equilibrium structural correlations, has been systematically applied to investigate gelation, localization, and elasticity of flexible polymer-hard particle suspensions. The particle volume fraction at the fluid-gel transition is predicted to depend exponentially on reduced polymer concentration and size asymmetry ratio at relativel… Show more

“…5(b)) the mean system dynamics becomes increasingly skewed toward localization. On the other hand, as pair attractions are increased, particles contained in the immobile clusters are themselves increasing bound to neighbors and thus localized [27]. Analysis of the full measured van Hove self-correlation functions (c.f.…”
