【28 Polymer】 The influence of molecular weight of polymer matrix on the structure and rheological properties of graphene oxide/polydimethylsiloxane composites
The structure and rheological properties of graphene oxide (GO)/polydimethylsiloxane (PDMS) composites are examined as the molecular weight of PDMS and concentration of GO are varied. Clusters formed by GO sheets get smaller and disperse better with increasing molecular weight of PDMS, which results in the higher critical concentration to form network (Ccr). Moreover, at GO concentration just abov...

【Polymer Chemistry】Large-Scale Fabrication of Polymer Ellipsoids with Controllable Patches via Viscosity-Induced Deformation of Spherical Particles
A simple and controllable strategy to synthesize polymer ellipsoids via the viscosity-induced deformation of spherical particles is proposed. These polymer ellipsoids can be employed as living seed particles to fabricate patchy ellipsoids with controlled protrusions. Most importantly, the methodology presented here will make a breakthrough in the preparation of ellipsoidal particles.

(Polymer) Magnetoresistive Conductive Polymer-Tungsten Trioxide Nanocomposites with Ultrahigh Sensitivity at Low Magnetic Field
The effect of conductive polymer matrix including polyaniline (PANI) and polypyrrole (PPy) on the magnetoresistance (MR) behaviors in the variable range hopping (VRH) regime has been investigated in the disordered polymer nanocomposites containing tungsten trioxide (WO3) nanoparticles. These nanocomposites have demonstrated ultrahigh MR sensitivity at low magnetic field regi...

Redox phospholipid polymer microparticles as doubly functional polymer support for immobilization of enzyme oxidase
We prepared redox phospholipid polymer microparticles for immobilizing an enzyme in order to maintain activity for a long time and obtain highly effective electron transfer to a gold substrate as an electrode. To achieve these double functions, an amphiphilic redox phospholipid polymer, poly(2-methacryloyloxyethyl phosphorylcholine-co-n-butyl methacrylate-co-p-nitrophenyloxycarbonyl oligo(ethyle...

[Polymer] Synthesis and thermally-triggered self-assembly behaviors of a dumbbell-shaped polymer carrying β-cyclodextrin at branch points
We report the design and synthesis of a thermally-responsive dumbbell-shaped polymer based on one b-cyclodextrin (β-CD)-terminated polyethylene glycol (PEG) segment and several poly(N-isopropylacrylamide) (PNIPAM) segments through combining click reaction with atom transfer radical polymerization. Thermally-triggered self-assembly and molecular inclusion behaviors of the polymer we...
