【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...

18 Striking influence of Fe2O3 on the "catalytic carbonization" of chlorinated poly(vinyl chloride) into carbon microspheres with high performance in the photo-degradation of Congo red
关键字：poly(vinyl chloride)
A one-pot approach was demonstrated to effectively synthesize carbon microspheres through “catalytic carbonization” of commercial chlorinated poly(vinyl chloride) (CPVC) microspheres by Fe2O3 at 700 °C. Without Fe2O3, a “sponge-like” carbon lump was obtained. However, after adding Fe2O3 (even 0.5 g per 100 g CPVC) into CPVC, carbon microspheres with octahedral Fe3O4 microcrystals uniformly em...

13 Catalytic carbonization of chlorinated poly(vinyl chloride) microfibers into carbon microfibers with high performance in the photo-degradation of Congo red
关键字：poly(vinyl chloride)
A simple approach was reported to prepare carbon microfibers embedded with octahedral Fe3O4 crystals (Fe/CMFs) through catalytic carbonization of chlorinated poly(vinyl chloride) (CPVC) microfibers using Fe3O4 as catalyst at 700 °C. Without Fe3O4, irregular carbon was obtained. However, after adding a proper amount of Fe3O4, carbon microfibers with uniform size were prepared. The influence of Fe3...

High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
关键字：poly(N-aryleneindole ether); pyridine; sensor; luminescence
A novel high-performance polyindole containing a pyridine ring (P1)was successfully prepared by the catalyst-free nucleophilic substitution polycondensation of 4-hydroxyindole with 2,6-difluoropyridine via a C?N and C?O coupling reaction process. This semirigid polyindole P1 exhibits good thermal stability, and it can be dissolved well in common organic solvents. Fluorescent spectral studies ind...

Facile synthesis of soluble aromatic poly(amide amine)s via C–N coupling reaction: Characterization, thermal, and optical properties
关键字：aromatic poly(amide amine)s; high-performance
Aromatic poly(amide amine)s (APAAs), as novel highperformance polymers, have been obtained by the condensation polymerization of N,N’-bis(4-bromobenzoyl)-p-phenylenediamine with two different primary aromatic diamines via palladiumcatalyzed aryl amination reaction. The structures of the polymers are characterized by means of FTIR, 1H NMR spectroscopy, and elemental analysis, the results show a ...

Facile and low-cost approach towards a PVDF ultrafiltration membrane with enhanced hydrophilicity and antifouling performance via graphene oxide/water-bath coagulation
关键字：ultrafiltration membrane
Addressed herein is a facile and low-cost approach to endow hydrophobic polyvinylidene fluoride (PVDF) membranes with reliable hydrophilicity and antifouling properties. Porous asymmetric hydrophilic membranes with tunable morphology were facilely fabricated via phase inversion using an aqueous solution of graphene oxide (GO) as the coagulation bath. An increment in pore size and surface rou...
