【15 Industrial & Engineering Chemistry Research】 Striking influence about HZSM-5 content and nickel catalyst on catalytic carbonization of polypropylene and polyethylene into carbon nanomaterials
A one-pot approach was established to effectively convert polypropylene (PP) and linear low density polyethylene (LLDPE) into carbon nanomaterials (CNMs) including cup-stacked carbon nanotubes and carbon nanofibers under the combined catalysis of HZSM-5/NiO or HZSM-5/Ni2O3 at 700 °C. The effects of HZSM-5 content, a nickel catalyst, and the carbon precursor on the morphology, microstructure, phas...

【09 Industrial & Engineering Chemistry Research】 Synergistic effect between a novel char forming agent and ammonium polyphosphate on flame retardancy and thermal properties of polypropylene
The performances of a novel char forming agent containing spiro and caged bicyclic phosphate (SBCPO) and its mixture with ammonium polyphosphate (APP) were investigated. The flame retardancy of the polypropylene (PP)/SBCPO/APP system was evaluated by the limiting oxygen index (LOI), the UL-94 test, and the cone calorimeter test. The maximum LOI value of PP/intumescent flame retardant (IFR) could r...

【Nano Research】A series of nanoparticles with phase-separated structures by 1,1-diphenylethene controlled one-step soap-free emulsion copolymerization and their application in drug release
A facile one-step approach to synthesize various phase-separated porous, raspberry-like, flower-like, core–shell and anomalous nanoparticles and nanocapsules via 1,1-diphenylethene (DPE) controlled soap-free emulsion copolymerization of styrene (S) with glycidyl methacrylate (GMA), or acrylic acid (AA) is reported. By regulating the mass ratio of S/GMA, transparent polymer solution, porous...

Journal of Polymer Science Part A: Polymer Chemistry 2011, 49(22), 4747
关键字：graphene; nanocomposites; SET-LRP; synthesis
A mild and efficient strategy is presented for growing thermo-sensitive polymers directly from the surface of exfoliated graphene oxide (GO). This method involves the covalent attachment of Br-containing initiating groups onto the surface of GO sheets followed by in situ growing poly[poly(ethylene glycol) ethyl ether methacrylate] (PPEGEEMA) via single-electron- transfer living radical polymerizat...
