Effects of Br Connected Groups on Atom Transfer Nitroxide Radical Coupling Reaction and Its Application in the Synthesis of Comb-Like Block Copolymers.
The effects of Br connected groups on atom transfer nitroxide radical coupling (ATNRC) reaction were investigated. Two precursors methoxyl poly(ethylene oxide)-b-poly(ethylene oxide-co-2-bromoiso butyryloxy glycidyl ether) (mPEO-b-Poly(EO-co-BiBGE)) and methoxyl poly(ethylene oxide)-b-poly(2-bromoiso butyryloxy glycidyl ether) (mPEO-b-Poly(BiBGE)) with different AC(CH3)2Br density were designed an...

New easy way preparation of core/shell structured SnO2@carbon spheres and application for lithium-ion batteries
关键字:Core/shell, Hollow carbon spheres, Tin oxide, Lithium-ion battery
A novel way for the synthesis of core/shell structures composed of tin oxide nanoparticles confined in mesoporous hollow carbon spheres (SnO2@MHCS) is newly reported. The materials which have a uniform size distribution, good structural stability and large surface area show superior cycling performance and are suitable for high-power anodes. Core/shell structured SnO2@MHCS takes advantage of the...
