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 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...

【61 Materials Chemistry Frontiers】 Simultaneously improving the mechanical properties and flame retardancy of polypropylene using functionalized carbon nanotubes by covalently wrapping flame retardant followed by linking polypropylene
The fabrication of polymer nanocomposites with improved physical and chemical properties is a hot topic in the fields of materials and chemistry. In this work, carbon nanotubes (CNTs) are functionalized through flame retardant wrapping and maleic anhydride polypropylene (PPMA) covalently attaching to achieve a compact char layer and strong interfacial adhesion. The resultant polypropylene (PP)/fun...

【59 Journal of Materials Chemistry A】 Nitrogen-doped porous carbon nanosheets derived from poly(ionic liquid): Hierarchical pore structures for efficient CO2 capture and dye removal
Poly(ionic liquid) has recently served as an important precursor for nitrogen-doped functional porous carbons. It was applied here in a facile one-pot approach to synthesize nitrogen-doped porous carbon nanosheets (NPCNSs) using C3N4 nanosheets as sacrificial templates. C3N4 nanosheets are found to improve the carbonization yield and nitrogen content of NPCNSs and additionally facilitate the forma...
