Glassy states in adsorbing surfactant–microgel soft nanocomposites

Mixtures of polymer-colloid hybrids such as star polymers and microgels with non-adsorbing polymeric additives have received a lot attention. In these materials, the interplay between entropic forces softness is responsible for wealth phenomena. By contrast, binary mixtures where one component can adsorb onto other been far less studied. Yet real formulations in applications often contain low molecular weight that soft colloids. Here we study microstructure rheology nanocomposites made surfactants using linear nonlinear rheology, SAXS experiments, cryoTEM techniques. The results are used to build dynamical state diagram encompassing various liquid, glassy, jammed, metastable, reentrant liquid states, which from subtle enthalpic, entropic, kinetic effects. We rationalize rheological properties each domain diagram, thus providing exquisite solutions designing new modifiers at will.
