Synthesis of three-arm poly(ethylene glycol) by combination of controlled anionicpolymerization and ‘click’ chemistry
关键字：controlled anionic polymerization, ‘click’ chemistry,three-arm poly(ethylene glycol),synthesis
Poly(ethylene glycol) (PEG) is an important water-soluble polymer, which is widely used in the biomedical field because
of its good biodegradability, biocompatibility and permeability. It is usually synthesized by anionic polymerization of
ethylene oxide but side reactions lead to the formation of some oligomers. High molecular weight PEG can be obtained,
however, through coordinated anionic po...

Journal of Polymer Science Part A: Polymer Chemistry 2012, 50(3), 571
关键字：ring-opening polymerization (ROP); reversible addition-fragmentation chain transfer (RAFT); controlled/“living” radical polymerization; star polymer
Reversible addition-fragmentation chain transfer (RAFT) polymerization is a more robust and versatile approach than other living free radical polymerization methods for synthesis of well-defined homo-, gradient, block, star-shaped and more complex structural polymers, like micro(nano)gels and polymer brushes. Thus the resultant polymers with thiocarbonylthio-terminated groups are readily tailored ...

【Journal Of Materials Chemistry A】Fe2O3-Decorated Millimeter-Long Vertically Aligned Carbon Nanotube Arrays As Advanced Anode Materials For Asymmetric Supercapacitor With High Energy And Power Densities
Construction of high-energy density asymmetric supercapacitors is often hindered by unsatisfactory matching between the anode and cathode. Thus, it is crucial to develop composite anodes with high specific capacitance to match that of cathodes. In this work, a novel anode material with well-dispersed Fe2O3 decorated on vertically aligned carbon nanotubes has been synthesized by a facile two-step...
