We investigate soft, temperature-sensitive microgels at fluid interfaces. Though having an isotropic, spherical shape in bulk solution, the become anisotropic upon adsorption. The structure of interfaces is described by a core–corona morphology. Here, we how changing temperature across microgel volume phase transition temperature, which leads to swelling/deswelling aqueous phase, affects behavior within monolayer. combine compression isotherms, atomic force microscopy imaging,...
Monolayers of polymer microgels adsorbed at the liquid interfaces were studied by dissipative particle dynamics simulations. The results demonstrated that compressibility monolayers can be widely tuned varying cross-linking density and their (in)compatibility with immiscible liquids. In particular, compression (increase 2D concentration microgels) leads to decrease lateral size. Herewith, shape individual soft particles gradually changes from oblate (diluted system) nearly spherical...
The structures of a molecular brush in good solvent are investigated using synchrotron small-angle X-ray scattering wide range concentrations. under study, PiPOx239-g-PnPrOx14, features relatively long poly(2-isopropenyl-2-oxazoline) (PiPOx) backbone and short poly(2-n-propyl-2-oxazoline) (PnPrOx) side chains. As solvent, ethanol is used. By model fitting, the overall size persistence length as well interaction strength determined. At this, interplay between form structure factor taken into...
Monolayers of polymer microgels with a spherical cavity adsorbed at the liquid-liquid interface were studied using mesoscopic computer simulations. One liquid, named water, was always considered as good solvent, while microgel solubility in second oil, varied. The symmetric and asymmetric cases vanishing strong differences between network particles liquids considered. simulations provided us an insight into shape volume changes upon compression, making it possible to relate response...
