Poly(phenylene sulfide) magnetic composites. I. Relations of percolation between rheology, electrical, and magnetic properties
Poly(phenylene sulfide)/ferrosoferric oxide composites (PPS/Fe3O4) with various loading levels were prepared by melt compounding. The microstructure of composites was investigated using SEM and XRD. The rheological, electrical and magnetic properties were characterized respectively by the parallel plate rheometer, high resistance meter, and magnetometer. The results reveal that the Fe3O4 part...

Poly(phenylene sulfide)/low-melting-point metal composites. I. Transient viscoelastic properties and crystallization kinetics
Poly(phenylene sulfide)/low-melting-point metal composites (PPSMs) with various loading levels were prepared by melt compounding. The nonisothermal crystallization behavior and transient viscoelastic properties were characterized by the DSC, POM, DMA, and parallel-plate rheometer. The results reveal that the low-melting-point metal (LMPM) particles show nice dispersion at relative low content leve...

Morphology evolution of nanocomposites based on poly(phenylene sulfide)/poly(butylene terephthalate) blend
Poly(phenylene sulfide) (PPS)/poly(butylene terephthalate) (PBT) (60/40 w/w) blend nanocomposites (PPS/PBTs) were prepared by direct melt compounding of PPS, PBT, and organoclay. The morphology and rheology of PPS/PBTs were investigated using scanning electron microscope and transmission electron microscope as well as parallel plate rheometer. The intercalated clay tactoids are selectively located...

Perfectly Alternating and Regioselective Copolymerization of Carbonyl Sulfide and Epoxides by Metal-Free Lewis Pairs
The preparation of perfectly alternating and regioslective copolymers derived from the copolymerization of carbonyl sulfide (COS) and epoxides by metal-free Lewis pair catalysts composed of a Lewis base (amidine, guanidine, or quaternary onium salts) and a Lewis acid (triethyl borane) is described. Colorless and highly transparent copolymers of poly(monothiocarbonat...

[Composites Part A]Synergistic improvement of thermal conductivities of polyphenylene sulfide composites filled with boron nitride hybrid fillers
Hybrid fillers of micrometer boron nitride/nanometer boron nitride (mBN/nBN) were employed to fabricate the highly thermally conductive insulating mBN/nBN/polyphenylene sulfide ((mBN/nBN)/PPS) composites via mechanical ball-milling followed by hot-compression method. The thermally conductive coefficient (λ), dielectric constant (ε) & dielectric loss tangent (t...

Composition controlled nickel cobalt sulfide core– shell structures as high capacity and good ratecapability electrodes for hybrid supercapacitors
Herein, we report a type of core–shell structured NixCo361xS4 (x = 1, 1.5 and 2) through tuning the ratios of Ni to Co by a simple two-step hydrothermal method. Scanning electron microscopy and transmission electron microscopy images of all the Ni–Co sulfides show high porosity and uniform spherical morphology. Moreover, this study demonstrates that controlling the appropriate ratio of Ni to Co ...

Catalytic Hydrogenation of Alkali Lignin to Bio-oil Using Fullerene-like Vanadium Sulfide
    The catalytic conversion of alkali lignin to chemicals has been the subject of intense research efforts during the past few decades. In thisstudy, VS2 catalysts, with different morphologies of sheets and nanoflowers, were prepared through hydrothermal methods and applied to the hydrogenation of alkali lignin. The conversion of alkali lignin and yield of bio-oil are 77.02 and 5...

Alternating copolymerization of carbonyl sulfide and Cyclohexene Oxide catalyzed by zinc–cobalt double metal cyanide complex
This paper describes the first example of alternating copolymerization of carbonyl sulfide (COS) with cyclohexene oxide (CHO) via heterogenous catalysis of a nano-lamellar zincecobalt(III) double metal cyanide complex (ZneCo(III) DMCC), providing an efficient method for converting COS to poly(cyclohexene monothiocarbonate) (PCHMTC) with an alternating degree up to 93%. The number-avera...

184. Nonenzymatic sensor for glucose based on a glassy carbon electrode modified with Ni(OH)2 nanoparticles grown on a film of molybdenum sulfide.
A glassy carbon electrode (GCE) was modified with nickel(II) hydroxide nanoparticles and a film of molybdenum sulfide. The nanocomposite was prepared by two-step electrodeposition. Scanning electron microscopy reveals that the nanoparticles are uniformly deposited on the film. Cyclic voltammetry and chronoamperometry indicate that this modified GCE displays a remarkable electrocatalytic activity t...

Poly(phenylene sulfide) Magnetic Composites. II. Crystallization, Thermal and Viscoelastic Properties. Polymer Engineering & Science, 2008, 48, 966-975.
Polymer Engineering & Science, 2008, 48, 966-975. ABSTRACT: Poly(phenylene sulfide)/ferrosoferric oxide composites (PPS/Fe3O4) with various loading levels were prepared by melt compounding. The crystallization, thermal and viscoelastic properties were characterized respectively by the DSC, DMA, TGA and parallel plate rheometer. The results reveal that the well dispersed Fe3O4 particle restr...
