Temperature-Responsive Phase Transition of Polymer Vesicles: Real-Time Morphology Observation and Molecular Mechanism
Novel thermosensitive polymer vesicles with controlled temperature-responsive phase transition at the lower critical solution temperature (LCST) varying from 8 to 81 °C were prepared via self-assembly of amphiphilic hyperbranched star copolymers having a hydrophobic hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane] (HBPO) core and many hydrophilic polyethylene oxide (PEO) arms. Real-time optic...

Parallel carbon nanotube stripes in polymer thin film with tunable microstructures and anisotropic conductive properties
It is known that shear-flow can induce units to assemble into vorticity-aligned stripe-structures in confined
geometries. This study shows that the microstructure and the property of the stripe in polymer thin
film can be well tuned by adjusting the viscosity ratio between dispersed phase and continuous phase.
Polypropylene (PP)/poly(styrene–ethylene/butadiene–styrene) (SEBS)/octadecylamine func...

Hollow Double-Layered Polymer Microspheres with pH and Thermo-Responsive Properties as Nitric Oxide-Releasing Reservoirs
Nitric
oxide-releasing hollow double-layered polymer microspheres (HDPMs) with both
pH- and thermo-responsive properties in aqueous media are designed and prepared
by a multi-step process. Silica/polymer (SiO2/P(bocAmEMA-co-EGDMA)) core-shell microspheres with boc-protected
secondary amino groups are synthesized by distillation precipitation copolymerization
of 2-(ethyl(boc)amino)ethyl methac...

[Chem. Commun.] A supramolecular hyperbranched polymer based on molecular recognition between benzo-21-crown-7 and secondary ammonium salt
A novel A2-B3-type supramolecular hyperbranched polymer was prepared based on the benzo-21-crown-7/secondary ammonium salt recognition motif. The resulting supramolecular polymer exhibited a reversible disassembled–assembled process by adding or removing potassium ions.

[Polymer] Large complex micelles formed from amphiphilic H-shaped terpolymers with adjustable block ratio by ultrasonic vibration
Large complex micelles based on H-shaped terpolymers (poly(ethylene glycol))(poly(N,N-dimethylaminoethyl methacrylate))-polytetrahydrofuran-(poly(N,N-dimethylaminoethyl methacrylate)) (poly(ethylene glycol)) ((PEG)(PDMA)-PTHF-(PDMA)(PEG)), with proper block ratio, are obtained through ultrasonic vibration. However, similar micellar morphology is not found using other traditional m...

Gradiently Varied Chain Packing/Orientation States of Polymer Thin Films Revealed by Polarization-dependent Infrared Absorption
Gradiently varied chain packing/orientation states of the polyacrylamide (PAL) thin films spin-coated on the gold (Au) substrates were found via the polarized reflection-absorption fourier transform infrared spectroscopy (RA-FTIR). As the film thickness increases, the splitted amide I bands provide a direct evidence that the PAL thin films are of a gradiently varied bi-layered structure. I...

A comparative study of viscoelastic planar contraction flow for polymer melts using molecular constitutive models
The benchmark problem of planar contraction flow is often used to evaluate the stability of numerical algorithms and the predictability of viscoelastic constitutive models in predicting the rheological behavior of polymer fluids. In this paper, for the simulation of planar contraction flow, the single/simplified modified double convected Pom–Pom (S–MDCPP) model recently proposed is adopted, an...

Enhanced water retention and proton conductivity of the proton exchange membranes by incorporating hollow polymer microspheres grafted with sulfonated polystyrene brushes
Hollow polymer microspheres grafted with sulfonated polystyrene brushes
(HPSS) were synthesized via combination of surface-initiated atom transfer
radical polymerization (SI-ATRP) of styrene from SiO2@P(MAA-co-DVB-co-CMSt)
core-shell microspheres, sulfonation of the polystyrene brushes, and finally
removal of the silica core. These HPSSs were then incorporated into the
sulfonated poly(ether e...

Facile one-step fabrication of polymer microspheres with high magnetism and armored inorganic particles by Pickering emulsion polymerization
Facile one-step Pickering emulsion polymerization was employed to prepare magnetic polymer microspheres with high magnetism and armored inorganic particles. Partially hydrophilic CTAB-modified Fe3O4 particles were employed as stabilizer of Pickering emulsion and were armored on the as-prepared microspheres, while totally hydrophobic oleic acid-modified Fe3O4 particles were encapsulated...
