Thermoresponsive polymere
Webb5 jan. 2024 · Thermoresponsive polymers are typical functional polymers that exhibit reversible phase-transition behavior when manipulated by thermal stimuli. Poly (N-isopropylacrylamide) (or p (NiPAAM)) is a well-known thermoresponsive polymer whose phase-transition temperature is approximately 32 °C [1], [2], [3]. WebbConsequently the polymer-polymer interactions become stronger than the polymer-solvent interactions, resulting in phase separation of the polymer takes place. The …
