213. Flexible free-standing 3D porous N-doped graphene–carbon nanotube hybrid paper for high-performance supercapacitors.
The nanoarchitecture of carbon with assembled building blocks on diverse scales is of great importance for energy storage. Herein, we demonstrate high-performance supercapacitors by building a three-dimensional (3D) porous structure that consists of a N-doped graphene–carbon nanotube (CNT) hybrid. The 3D porous nitrogen-doped graphene–CNT (p-N-GC) hybrid paper was fabricated by using polystyrene...

81. Preparation of N-doped carbon quantum dots for high-sensitive detection of dopamine by electrochemical method
A simple electrochemical biosensor was developed based on N-doped carbon quantum dots (NCQDs) modified glass carbon electrode (NCQDs/GCE). The modified electrode displayed a good linear and broad response for detection of dopamine (DA). The as-prepared biosensor also exhibited satisfactory selectivity even the interference of ascorbic acid (AA) and uric acid (UA). The inorganic ions had no...

Char barrier effect of graphene nanoplatelets on the flame retardancy and thermal stability of high-density polyethylene flame-retarded by brominated polystyrene
Char barrier effect of graphene nanoplatelets (GNPs) on the flame retardancy and thermal stability of high-density polyethylene (HDPE) flame-retarded by brominated polystyrene (BPS) and antimony oxide (Sb2O3) was investigated. Thermogravimetric (TG) analysis, limited oxygen index (LOI) and vertical burning test (UL-94) showed that the presence of GNPs led to enhanced thermal oxidation stability an...

Facile one-step fabrication of polymer microspheres with high magnetism and armored inorganic particles by Pickering emulsion polymerization
Facile one-step Pickering emulsion polymerization was employed to prepare magnetic polymer microspheres with high magnetism and armored inorganic particles. Partially hydrophilic CTAB-modified Fe3O4 particles were employed as stabilizer of Pickering emulsion and were armored on the as-prepared microspheres, while totally hydrophobic oleic acid-modified Fe3O4 particles were encapsulated...

Fabrication of highly dispersed ZnO nanoparticles embedded in graphene nanosheets for high performance supercapacitors
We report a facile strategy to synthesize ZnO-graphene nanocomposites as an advanced electrode material for high-performance supercapacitors. The ZnO-graphene nanocomposites have been fabricated via a facile, low-temperature in situ wet chemistry process. During this process, high dispersed ZnO nanoparticles are embedded in graphene nanosheets, leading to sandwich-structured ZnO-graphene nanocom...

Synthesis and Characterization of Comb and Centipede Multigraft Copolymers PnBA-g-PS with High Molecular Weight Using Miniemulsion Polymerization
Comb and centipede multigraft copolymers, poly(n-butyl acrylate)-g-polystyrene (PnBA-g-PS) with PnBA backbones and PS side chains, were synthesized via high-vacuum anionic polymerization and miniemulsion polymerization. Single-tailed and double-tailed PS macromonomers were synthesized by anionic polymerization and Steglich esterification. Subsequently, the copolymerization of each macromonomer a...

MacromolRapidCommun--Tellurium-based polymeric surfactants as a novel seleno-enzyme model with high activity
A tellurium-based polymeric sufactant as a seleno-enzyme model has been constructed by employing 11-acryloyloxyundecyltriethylammonium bromide (AUTEAB, 4) and a tellurium-containing compound (1). It demonstrates strong substrate binding ability for thiols and high glutathione peroxidase (GPx) activity about 6 orders of magnitude more efficient than the well-known GPx mimic PhSeSePh in an ArSH assa...
