Direct Observation of the Lower Critical Solution Temperature of Surface-Attached Thermo-Responsive Hydrogels by Surface Plasmon Resonance

The precipitation of thermo‐responsive polymers from solution on heating is a well‐known phenomenon. But how do such polymers behave at interfaces? By direct observation, with surface plasmon resonance, of the thermo‐responsive effect of a polymer grafted to a gold surface, it was shown that the pol...

Summary:The precipitation of thermo‐responsive polymers from solution on heating is a well‐known phenomenon. But how do such polymers behave at interfaces? By direct observation, with surface plasmon resonance, of the thermo‐responsive effect of a polymer grafted to a gold surface, it was shown that the polymer undergoes a phase transition even at the interface (see picture) at the lower critical solution temperature (LCST).
