Preparation and Characterization of Polyamide4(PA4)-Polyurethane(PU)-PA4 Triblock Copolymers

Clickable Amphiphilic Triblock Copolymers.

Amphiphilic polymers have recently garnered much attention due to their potential use in drug-delivery and other biomedical applications. A modular synthesis of these polymers is extremely desirable since it offers precise individual block characterization and increased yields. We present here for the first time a modular synthesis of poly(oxazoline)-poly(siloxane)-poly(oxazoline) block copolym...

Preparation of echinoid-like aggregated hematite particles by forced hydrolysis with PEO-PPO-PEO triblock copolymers

Sub-micrometre sized hematite particles with a controlled structure were prepared by forced hydrolysis of a Fe(NO3)3·9H2O aqueous solution in the presence of poly(alkylene oxide) triblock copolymer (Pluronic P123). The resulting particles show an echinoid-like shape and a narrow size distribution. After removal of the polymer by calcination at 500 C for 3 h, the resulting particles show a retai...

Self-assembled architectures from biohybrid triblock copolymers.

The synthesis and self-assembly behavior of biohybrid ABC triblock copolymers consisting of a synthetic diblock, polystyrene-b-polyethylene glycol (PSm-b-PEG113), where m is varied, and a hemeprotein, myoglobin (Mb) or horse radish peroxidase (HRP), is described. The synthetic diblock copolymer is first functionalized with the heme cofactor and subsequently reconstituted with the apoprotein or ...

Preparation and Characterization of Thermo-Responsive Rod-Coil Diblock Copolymers

In this study, we synthesized amphiphilic poly(2,7–(9,9–dioctylfluorene))–block–N,N– (diisopropylamino)ethyl methacrylate (POF–b–PDPMAEMA) rod-coil diblock copolymers by atom transfer radical polymerization (ATRP). The structure and multifunctional sensing properties of these copolymers were also investigated. The POF rod segment length of 10 was fixed and the PDPAEMA coil segment lengths of 90...
