142. Fabrication and Characterization of Ultrathin Graphene Oxide/Poly(Vinyl Alcohol) Composite Films via Layer-by-Layer Assembly.
Novel multilayer ultrathin ?lms comprised of graphene oxide (GO) and poly(vinyl al-
cohol) (PVA) were fabricated through a layer-by-layer (LBL) assembly technique. GO
could self-assemble onto quartz substrates alternately with PVA via hydrogen-bonding interactions. X-ray diffraction, atomic force microscopy, and transmission electron microscopy analysis revealed that GO was exfoliated to monolay...

Preparation of well-de?ned blackberry-like polypyrrole/?y ash composite microspheres and their electrical conductivity and magnetic properties
Composites consisting of conducting polypyrrole (PPy) and ?y ash (FA) or amino-functionalized ?y ash
(A-FA) were prepared by the in situ chemical oxidative polymerization method, respectively. The surface
functionalization of ?y ash (FA) with amino groups was found to play an important role in the formation
of the well-de?ned blackberry morphology. The scanning electron microscopy (SEM) analysi...

11. Studies on interface structure and crystal texture of poly(ether-ether-ketone)-carbon fiber composite
The interface structure of poly(ether-ether-ketone) (PEEK)-carbon fibre composite and the crystal texture of PEEK matrix have been studied by scanning electron microscopy (SEM) after the samples were properly etched by argon plasma. We find that most of the PEEK'S crystals are induced by nucleating carbon fibre and then they developed the transcrystalline or spherulite shape, depending on the...

Hypochlorite treatment on thin film composite RO membrane to improve boron removal performance
Controlled hypochlorite treatment was conducted on three commercial RO membranes to improve their boron removal performance. The effects of hypochlorite treatment on membrane performance, including permeate flux, NaCl rejection as well as boron removal were investigated. The effect of pH of feed water on both original and chlorinated membranes was also investigated. In order to better understand t...

Banded Spherulites of Electrospun Poly(trimethylene terephthalate)/Carbon Nanotube Composite Fiber Mats
Polymer International, 2011, 60(10), 1497-1503.
ABSTRACT:
The crystallization of poly(trimethylene terephthalate) (PTT) composites containing carbon nanotubes (CNTs) were studied in this work. The electrospinning technology was employed to fabricate thin film samples with well-embedded CNTs for the spherulite observations using atom force microscopy (AFM). The results show that the composites p...

The Core/Shell Composite Nanowires Produced by Self-Scrolling Carbon Nanotubes onto Copper Nanowires
We demonstrated a novel method to produce core/shell composite nanowires (NWs) by selfscrolling carbon nanotubes (CNTs) onto copper NWs via forced-field-based molecular dynamic (MD) simulations. When large diameter CNTs are placed beside the copper NWs, the CNTs approach the NWs, collapse, and self-scroll onto the NWs, resulting in coaxial core/shell composite NWs. It is found that the van der Waa...

Electrospun palladium (IV)-doped copper oxide composite nanofibers for non-enzymatic glucose sensors
Pd (IV)-doped CuO oxide composite nanofibers (PCNFs) have been successfully fabricated via electrospinning and then employed to construct an amperometric non-enzymatic glucose sensor. The PCNFs based glucose sensors display distinctly enhanced electrocatalytic activity towards the oxidation of glucose, showing significantly lower overvoltage (0.32 V) and ultrafast (1 s) and ultrasensitive current ...

Computational analysis of effect of modification on the interfacial characteristics of a carbon nanotube–polyethylene composite system
In this study, the non-covalent association of single-walled nanotube (SWNT) with polyethylene (PE) molecule and the influence of sidewall modification on the interfacial bonding between the SWNTs and polymer were investigated using molecularmechanics (MM) andmolecular dynamics (MD) simulations.
The model of interaction between the initially separated PE and SWNT fragments, which can be either wr...
