[Adv. Funct. Mater.] 2D Janus Hybrid Materials of Polymer Grafted Carbon Nanotube/ Graphene Oxide Thin Film as Flexible, Miniature Electric Carpet
Ultrathin, freestanding
polymer hybrid film with macroscopic sizes and molecular thicknesses have
received significant interest due to their applications as functional devices, microsensors
or nanoactuators. Herein, it is demonstrated that 2D Janus hybrid materials of
polymer grafted carbon nanotubes/graphene oxide (CNTs/GO) thin film was
fabricated using micro-contact printed CNTs/GO as photo act...

In vitro degradation of biodegradable blending materials based on poly(p-dioxanone) and poly(vinyl alcohol)-graft-poly(p-dioxanone) with high molecular weights
Amphiphilic biodegradable graft copolymer, poly(vinyl alcohol)-graft-poly(p-dioxanone) (PVA-g-PPDO), was used to prepare a new biodegradable material by blending with poly(p-dioxanone) (PPDO). The in vitro degradation properties of the copolymer and blends with different contents of PVA-g-PPDO were studied in phosphate buffer at 37 degrees C. The degradation processes of the PVA-g-PPDO and its ble...

Leaf-like V2O5 Nanosheets Fabricated by a Facile Green Approach as High Energy Cathode Material for Lithium-Ion Batteries, Advanced Energy Materials, 2013, 3(9): 1171–1175
In summary, we have developed a facile, green, and lowcost
synthesis of 2D leaf-like V 2 O 5 nanosheets. The unique
nanoscale characteristics, including 2D morphology, hierarchical
porous structure, large specifi c surface, of these 2D V 2 O 5
nanosheets leads to the superior electrochemical performance
in terms of their specifi c capacity, rate capability, and cyclability
when they are used as a ...

Journal of Materials Chemistry 2011: One-pot preparation of polyethylenimine-silica nanoparticles as serum-resistant gene delivery vectors: Intracellular trafficking and transfection
Organic-inorganic hybrid silica nanoparticles (PM-1, PM-2 and PM-3) with positive surface charge and size below 200 nm were one-pot prepared via Michael addition between 3-methacryloxypropyl-trimethoxysilane (MPTMS) and polyethylenimine (PEI), followed by hydrolysis and polycondensation of siloxanes. The nanoparticles were characterized by FT-IR, element analysis and particle size analysis. The av...

Silk Fibers Extruded Artificially from Aqueous Solutions of Regenerated Bombyx mori Silk Fibroin are Tougher than their Natural Counterparts. Advanced Materials, 2009, 21(3): 366-370
Zhou GQ, Shao ZZ, Knight DP, Yan JP, Chen X*
The superior mechanical strength of certain spider dragline silks and of silk reeled artificially silk from silkworm larvae have lead to several attempts to extrude fibres from redissolved silk fibroin. These have, with a single exception, produced fibres weaker than the natural ones. The best process to date produced stronger ones but was u...

22. Crystallization kinetics and hydrophilicity improvement of biodegradable poly(butylene succinate) in its miscible blends with poly(ethylene oxide). Lu J, Qiu Z,* Yang W. Macromolecular Materials and Engineering 2008; 293 (11): 930-938.
The sphemlitic morphology and growth, overall isothermal crystallization kinetics and hydrophilicity of PBSU were investigated by POM, DSC and WCA measurements in its miscible blends with PEO. The Hoffman-Lauritzen equation was employed to analyze the spherulitic growth rates of neat and blended PBSU, which show a crystallization regime transition between regime II and III. The overall crystalliza...

Synthesis of High-Performance Polymers via Copper-Catalyzed Amination of Dibromoarenes with Primary Aromatic Ether Diamines
关键字：poly(imino ether ketone)s, heat-resistant polymer, copper-catalysis, foam.
In this paper, we introduce three high-performance polymers with similar structures, poly(imino ether ketone) (PIEK)s, which are synthesized by the ligand free copper-catalyzed C-N cross coupling reaction of aryl halides and primary aromatic diamines at moderate temperature. The influence of the solvents, base, temperature, and catalyst ligands on the polycondensation reaction is investigated. T...

High performance organic sensitizers based on 11,12-bis(hexyloxy) dibenzo[a,c]phenazine for dye-sensitized solar cells
关键字：organic sensitizers, dye-sensitized solar cells, 11,12-bis(hexyloxy) dibenzo[a,c]phenazine
Three new metal-free organic sensitizers containing 11,12-bis(hexyloxy) dibenzo[a,c]phenazine (BPz) units were synthesized and used for dye-sensitized solar cells (DSSCs). The broad absorption spectra indicate that the light harvesting abilities were enhanced by the introduction of the BPz unit in the p-conjugated space, which can also cause an anti-aggregation effect and the suppression of charge...

A New Low-Bandgap Polymer Containing Benzene-Fused Quinoxaline: Significantly Enhanced Performance Caused by One Additional Benzene Ring
关键字：benzene-fused quinoxaline; low-bandgap; polymer solar cells
Two new alkoxy-substituted quinoxaline (Qx)-based copolymers, PBDTQx and PBDTPz, are
designed and synthesized. The only difference between these two polymers is that two methyl groups of the Qx are replaced by one additional fused benzene ring. The UV–Vis absorptions, thermal stability, energy levels, fi eld-effect carrier mobility, and photovoltaic characteristics of the two copolymers are sys...
