pH- and temperature-responsive aqueous foams stabilized by hairy latex particles.
Polystyrene (PS) particles carrying pH- and temperature-responsive poly[2-(dimethylamino)ethyl methacrylate] (PDMA) hairs (PDMA-PS particles) were synthesized by dispersion polymerization. The diameter, diameter distribution, morphology, chemical composition and surface chemistry of the particles were characterized using scanning electron microscopy (SEM), elemental microanalysis, dynamic light...
متن کاملPolymer adsorption on colloidal particles
2014 We consider the adsorption of polymers on colloidal particles 2014 spheres and cylinders 2014 whose dimensions are comparable to solution polymer radii of gyration. Adsorption occurs if the « sticking energy » per monomer exceeds a certain threshold. For a colloidal particle, this threshold increases by an amount inversely proportional to its radius. In addition, the repulsive interactions...
متن کاملFluid-bicontinuous emulsions stabilized by colloidal particles
Using controlled spinodal decomposition, we have created a fluid-bicontinuous structure stabilized by colloidal particles. We present confocal microscopy studies of these structures and their variation with kinetic pathway. Our studies reveal a rigid multilayer of colloidal particles jammed at the interface which prevents the liquids demixing for many hours. The arrangement of two-fluid domains...
متن کاملBicontinuous emulsions stabilized solely by colloidal particles.
Recent large-scale computer simulations suggest that it may be possible to create a new class of soft solids, called 'bijels', by stabilizing and arresting the bicontinuous interface in a binary liquid demixing via spinodal decomposition using particles that are neutrally wetted by both liquids. The interfacial layer of particles is expected to be semi-permeable; hence, if realized, these new m...
متن کاملPolymer depletion profiles around nonspherical colloidal particles.
We study the effect of chain self-avoidance on the polymer density profiles that are induced by a single colloidal particle of nonspherical shape such as an ellipsoid, a dumbbell, or a lens in a solution of nonadsorbing polymers. For colloid sizes sigma much smaller than the size R(x) of the polymers, we observe a pronounced difference between ideal and self-avoiding chains. In the case of idea...
