Temperature‐Sensitive Core–Shell Microgel Particles with Dense Shell

Abstract

Cores and effect: Using different temperature-sensitive polymers a core–shell microgel is prepared, which at intermediate temperatures has a shell with a higher segment density Φ than the core (see radial density profiles: core (red), shell (blue)). More detailed information is obtained from small-angle neutron scattering. A new form-factor model describes the experimental scattering curves at different temperatures.
