Thermoresponsive Diblock Copolymer with Tunable Soluble–Insoluble and Soluble–Insoluble–Soluble Transitions
Copyright policy )Thermoresponsive Diblock Copolymer with Tunable Soluble–Insoluble and Soluble–Insoluble–Soluble Transitions
AbstractThe thermoresponsive transition behavior of a diblock copolymer consisting of poly(ethylene glycol) methyl ether (mPEG) and poly(N,N‐dimethylaminoethyl methacrylate) (PDMAEMA) in aqueous solutions has been investigated. With a specific composition, the copolymer showed a unique tunable phase transition from no response in acidic media to a soluble–insoluble (S‐I) transition in neutral media and an S‐I‐S transition in basic media either in the presence of salt or for salt‐free solutions. The S‐I‐S transition can be tuned over a wide temperature range even to an S‐I type transition just by adding salts. In addition, phase transitions can occur in both pure water and saline solution under practical conditions (30–80 °C), which makes them suitable for a broad range of applications.magnified image
