Thermoresponsive reversible behavior of multistimuli pluronic-based pentablock copolymer at the air-water interface.
Surface behavior of the pH- and thermoresponsive amphiphilic ABCBA pentablock copolymer has been studied with respect to the environmental conditions. We demonstrate that the pentablock copolymer poly((diethylaminoethyl methacrylate)-b-(ethylene oxide)-b-(propylene oxide)-b-(ethylene oxide)-b-(diethylaminoethyl methacrylate)) possesses reversible temperature changes at the air-water interface i...
متن کاملCharacterization of a sulfonated pentablock copolymer for desalination applications
Water and salt transport properties were determined in a family of sulfonated pentablock copolymers to characterize their potential as chlorine-tolerant desalination membrane materials. The degree of sulfonation, block molecular weight, and casting conditions can be independently varied to tune the transport properties of these materials. Data for water uptake, water permeability, salt permeabi...
متن کاملpH- and temperature-dependent phase behavior of a PEO-PPO-PEO-based pentablock copolymer in aqueous media.
We investigated the structural features of micelles formed by the self-association of the pentablock copolymer poly[ N,N -(diethyl amino)ethyl methacrylate]-block-poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethyleneoxide)-block-poly[ N,N -(diethylamino)ethyl methacrylate] (PDEAEM-PEO-PPO-PEO-PDEAEM) in aqueous solutions by using small-angle neutron scattering SANS. The pentabloc...
متن کاملSynthesis and characterization of diblock and gel-forming pentablock copolymers of tertiary amine methacrylates, poly(ethylene glycol), and poly(propylene glycol)
Novel pH-sensitive gel-forming pentablock copolymers based on commercially available Pluronic (poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide), PEO-b-PPO-b-PEO) triblock copolymers and cationic diblock copolymers based on polyethylene glycol) methyl ether (PEGME) were synthesized by oxyanionic polymerization. Polymerization of the cationic moiety, poly((diethylamino)-ethyl m...
متن کاملFlexible thermoresponsive nanomembranes at the aqueous-air interface.
A synthetic pathway is described to construct thermoresponsive freestanding nanomembranes at the aqueous-air interface of a pendant drop. Dynamic control of the reaction kinetics allows formation of viscoelastic interfaces supporting anisotropic stresses and mechanical stability, which can be tuned by external stimuli.
