“…Stimuli-responsive polymers are able to respond to the external environment and exhibit reversible or irreversible changes in their chemical structure and physical properties. − Various types of stimuli, e.g., light, , gas, , pH, , mechanical forces, , temperature, , electric field, , and magnetic field, , have been applied to trigger the changes of the chain conformation, self-assembly, and solubility of stimuli-responsive polymers. As an important type of stimuli-responsive polymers, thermoresponsive polymers with a lower critical solution temperature (LCST) attract significant attention both in theories and applications due to their fast response, high sensitivity, and easy control of temperature response. − Typically, when the external temperature is below the transition temperature (TT), thermoresponsive polymers with LCST behavior are more hydrophilic, since intermolecular hydrogen bonds between water molecules and polymer chains can be formed.…”
