[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...

暨南大学刘明贤教授课题组ACS AMI：聚硅氧烷改性埃洛石纳米管涂覆的高效超疏水聚氨酯泡沫
关键字：超疏水，聚氨酯泡沫
勘探，生产，精炼和运输过程中的石油泄漏难以控制，这对环境会造成灾难性的破坏。石油污染对海鸟和其他海洋生物构成了巨大的威胁。泄漏的油污可能通过食用的鱼类和贝类富集在人类体内，并且会污染地下水。因此，需要新的有效解决策略来解决一直存在的土壤和海洋污染问题。
近日，暨南大学刘明贤教授团队与美国路易斯安那理工大学的Yuri Lvov教授合作，在ACS Applied Materials & Interfaces...

陕西科技大学张美云教授团队《ACS Nano》：省时高效制备芳纶纳米纤维研究获进展
关键字：芳纶纳米纤维，纳米复合材料，ANFs
芳纶纳米纤维（aramid nanofibers, ANFs）作为近年来开发的一种新型纳米高分子材料，兼具对位芳纶纤维（PPTA）和高分子纳米纤维的双重优势，可解决芳纶纤维存在的表面光滑惰性强、复合界面强度弱等问题。同时，ANFs可与聚合物基体通过物理/化学/自组装交联作用高效复合，使其成为构建高性能复合材料极具潜力的“增强构筑单元“，在纳米复合材料领域起着重要的界面增强作用。然而，利用宏观PPTA纤维通过去质子化法制...
