These systems consist of aqueous suspensions of core–shell particles having a solid polystyrene core and a shell of thermosensitive crosslinked poly(N- isopropylacrylamide) (PNIPA). In cold water the thermosensitive PNIPA-network is swollen leading to a high effective volume fraction of the particles in suspension. Approaching the volume transition at 32 °C the network shrinks by expelling water. Hence, the effective volume fraction can be adjusted by the temperature. We demonstrate that these suspensions are a well-characterized model system for the study of the flow behavior of concentrated suspensions. In particular, experimental work done on this system can be compared to the predictions of the modecoupling theory (MCT) of the fluid-to-glass transition. Excellent agreement is found demonstrating that MCT captures the essential features of the dynamics of flowing suspensions. In particular, MCT predicts a melting of the glass by shear which is fully corroborated by the experimental data.</dcterms:abstract> <dc:language>eng</dc:language> <dspace:hasBitstream rdf:resource=""/> <dcterms:title>Core-shell microgels as model colloids for rheological studies</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> </rdf:Description> </rdf:RDF>
