Optimization of mechanical and dielectric properties of poly(urethane–urea)-based dielectric elastomers via the control of microstructure
In this work, we fabricated novel poly(urethane–urea) (PUU)-based dielectric elastomers using a hydroxylterminated butadiene–acrylonitrile copolymer (HTBN) as the soft segment and hexamethylene diisocyanate (HDI) and 3,30-dimethyl-4,40-diamino dicyclohexyl methane (DMDC) as hard segments. The effect of hard segment (HS) content on the hard domain (HD) structure, morphology, dielectric and mechan...

8.【J. Phys. Chem. B】Network Structure Control of Binary Mixed Langmuir Monolayers of Homo-PS and PS-b-P2VP.
Our recent work showed there existed a composition window for mixed Langmuir monolayers of homopolystyrene (h-PS) and a symmetric diblock copolymer polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) to form necklace-network structures at the air/water interface. In order to study further the possible mechanism and control the network structure (i.e., surface coverage and nanoaggregate diameter)...

Stereoselective Copolymerization of Unprotected Polar and Nonpolar Styrenes by an Yttrium Precursor: Control of Polar-Group Distribution and Mechanism
Styrene underwent unprecedented coordination–insertion copolymerization with naked polar monomers (ortho-/meta-/para-methoxystyrene) in the presence of a pyridyl methylene fluorenyl yttrium catalyst. High activity (1.26×106 g·molY-1 h-1) and excellent syndioselectivity were observed, and high-molecular-weight copolymers (24.6×104 gmol-1) were obtained. The insertion rate...

Stereoselective Copolymerization of Unprotected Polar and Nonpolar Stryenes by an Yttrium Precursor:Control of Polar-Group Distribution and Mechanism.
Styrene underwent unprecedented coordinationinsertion copolymerization with naked polar monomers (ortho-/ meta-/ para-methoxystyrene) in the presence of a pyridyl methylene fluorenyl yttrium catalyst. High activity (1.26 X 10(6) gmol(Y)(- 1)h (-1)) and excellent syndioselectivity were observed, and high-molecular-weight copolymers (24.6 X 10(4) gmol (-1)) were obtained. The insertion rate of the...

Concentration-driven phase control for low temperature synthesis of phase-pure anatase and rutile titanium oxide
It is highly desirable to develop controlled synthetic methods at low temperature (<100 °C) for defined phases of titanium oxide nanoparticle. We present here a simple low temperature approach which is based on the peroxide route. This approach allows the preparation of phase-pure rutile and anatase without the use of any additives or surfactants or external acids. The formation of crystalline...

Solvothermal synthesis of hierarchical Eu2O3 nanostructures templated by PS-b-PMAA: morphology control via simple variation of water contents.
A new method to synthesize hierarchical Eu203 nanostructures via a solvothermal process in N,N''''-dimethyl formamide (DMF) templated by an ionic amphiphilic diblock copolymer polystyrene-block-poly (methacrylic acid) (PS-b一PMAA) has been developed. By simply varying the mass ratio of HZO over DMF from 0 to 20 wt% in the polymer-salt mixed solution, a series of Eu203 morphologies including worm...

Effective Morphology Control in an Immiscible Crystalline/Crystalline Blend by Artificially Selected Viscoelastic Phase Separation Pathways
We investigated the interplay between viscoelastic phase separation (VPS) and crystallization in a dynamically asymmetric crystalline/crystalline polymer blend
system of poly(butylene succinate) (PBS)/poly(ethylene oxide) (PEO). The dynamic asymmetry came from the large molecular weight difference between the slow relaxing PEO and the fast relaxing PBS molecules. The evolution of networklike struc...

Soft Matter, 2011, 7, 8932-8941; Chemical modification of bioinspired superhydrophobic polystyrene surfaces to control cell attachment/proliferation
Surface chemistry is known to have a profound influence on cellular behavior. However, the cells'' responses on surfaces exhibiting extreme wettability values are not yet fully understood. In this work, bioinspired superhydrophobic polystyrene (PS) surfaces were produced by a phase separation method and the in vitro performance of three different cell lines (SaOs-2, L929 and ATDC5) was...
