Absence of crystals in the phase behavior of hollow microgels

Solutions of microgels have been widely used as model systems to gain insight into atomic condensed matter and complex fluids. We explore the thermodynamic phase behavior hollow microgels, which are distinguished from conventional colloids by possessing a central cavity. Small-angle neutron X-ray scattering probe in crowded environments. These measurements reveal an interplay between interpenetration deswelling, unusual absence crystals. Monte Carlo simulations microgel solutions confirm that, due cavity, they form supercooled liquid more stable than case with crosslinked core.
