Logarithmic chain-exchange kinetics of diblock copolymer micelles.
We present a study of equilibrium chain-exchange kinetics of a well-defined model system for starlike polymeric micelles. The results show that the kinetics follows a logarithmic time dependence. The same feature has been confirmed for two other micellar systems. This is in sharp contrast to theoretical predictions and hints towards strongly coupled chain dynamics within the micellar cores indu...
متن کاملVisualizing worm micelle dynamics and phase transitions of a charged diblock copolymer in water.
Assemblies of block copolymer amphiphiles are sometimes viewed as glassy, frozen, or static colloids, especially in strongly segregating solutions. Here, we visualize by fluorescence microscopy and AFM the dynamics and transitions of single cylindrical micelles and vesicles composed of a charged diblock copolymer in water. In mapping the salt- and pH-dependent phase diagrams of a near-symmetric...
متن کاملAmphiphilic Diblock Copolymer Surface
10 11 Both visible and infrared (IR) spectroscopic ellipsometry have been employed to study the 12 structure of thin layers of bovine submaxillary mucin (BSM) adsorbed on poly(acrylic acid13 block-methyl methacrylate) (PAA-b-PMMA) copolymer and poly(methyl methacrylate) 14 surfaces at three pH values (3, 7 and 10). The adsorbed mucin layer on the copolymer surface 15 had the greatest thickness ...
متن کاملBlock copolymer micelle nanolithography
Au-nanoclusters between 2 and 8 nm in diameter were deposited onto solid substrates in different pattern geometries. The basis of this approach is the self-assembly of polystyrene-b-poly[2-vinylpyridine (HAuCl4)] diblock copolymer micelles into uniform monomicellar films on solid supports such as Si-wafers or glass cover slips. HAuCl4 as metallic precursor or a single solid Au-nanoparticle caus...
متن کاملThermally induced micelle to vesicle morphology transition for a charged chain end diblock copolymer.
A quaternary amine end functionalised diblock copolymer (PtBuA-b-PNIPAM) has been synthesised using RAFT polymerisation and shown to undergo a thermally induced morphology transition from micelles to vesicles, as evidenced by TEM, AFM, SLS and DLS analyses.
