Abstract

Excellent quantitative agreement with the structural predictions of the microscopic Polymer reference interaction site model (PRISM) theory over a wide range of length scales, volume fractions, solvency conditions, polymer sizes and polymer concentrations were documented. Agreement between theory and experiment breaks down on local cage and mesoscopic length scales as suspensions "fall out" of equilibrium at the gelation transition. This paper explores the ability of MCT with PRISM theory input to describe gel boundaries and elastic moduli of colloid-polymer suspensions characterized by short-range depletion attractions.
