Interfacial Thermodynamics of Coexisting Aqueous Polymer Solutions

Listed in DANS Data Station Physical and Technical Sciences

Description

This dataset belongs to the PhD thesis of Mark Vis, "Interfacial Thermodynamics of Coexisting Aqueous Polymer Solutions" (Utrecht University, 2015). This dataset contains supplementary movies to Chapter 5. A PDF copy of the PhD thesis is included and can also be accessed through Utrecht University’s library, dspace.library.uu.nl/handle/1874/323671.

Abstract of Chapter 5: Ultrathin plate-like colloidal particles are effective candidates for Pickering stabilization of water-in-water emulsions, a stabilization that is complicated by the thickness and ultralow tension of the water–water interface. Here we present experiments and theory for the effect of gibbsite nanoplates on phase-separated aqueous solutions of biopolymers dextran and nongelling fish gelatin. Plate-like particles have the advantage of blocking much of the interface while simultaneously having a low mass.

Additionally, the amount of blocked interface is practically independent of the equilibrium angle θ at which the water–water interface contacts the nanoplates, as opposed to the wetting of spheres. As a result, the adsorption of nanoplates is stronger than for spheres with the same maximal cross section, except at θ = 90°.
