Weakly Interacting Colloid Polymer Mixtures
This thesis explores the physics of weakly interacting colloid-polymer mixtures. Colloid-polymer mixtures can consist of two kinds of interactions; depletion and adsorption. Both interactions can lead to colloidal aggregation and formation of space spanning gels that can bear stress. Depending on the range of the attractive interaction, depletion gels bear stress by two mechanisms; bond-stretch...
متن کاملPhase Behaviour of Colloid + Polymer Mixtures
A new treatment of the phase behaviour of a colloid + nonadsorbing polymer mixture is described. The calculated phase diagrams show marked polymer partitioning between coexisting phases, an effect not considered in the usual effective-potential approaches to this problem. We also predict that under certain conditions an area of three-phase coexistence should appear in the phase diagram. Introdu...
متن کاملInteractions in mixtures of colloid and polymer
2014 We report results of light scattering study of interactions in a mixture of a surfactantstabilized colloid and hydrogenated polyisoprene polymer. With a virial expansion the smallangle scattering intensity from the mixture is calculated as a function of colloid and polymer concentrations. Using the obtained formula we measured the mutual excluded volume between a polymer molecule and a col...
متن کاملThe structure of colloid-polymer mixtures
– We investigate the structure of colloid-polymer mixtures by calculating the structure factors for the Asakura-Oosawa model in the PY approximation. We discuss the role of potential range, polymer concentration and polymer-polymer interactions on the colloid-colloid structure. Our results compare reasonably well with the recent experiments of Moussäıd et al. (Moussäid A., Poon W. C. K., Pusey ...
متن کاملDynamics of confined colloid-polymer mixtures
We investigate the effect of confinement on particle dynamics in mixtures of colloidal particles and non-adsorbing depletant polymers that serve as models for attractive suspensions. Holding the volume fraction of particles and the polymer concentration constant, the dynamics of the particles become increasingly slow as the suspensions are confined in thin wedgeshaped cells. Confocal micrograph...
