a b s t r a c t The preparation and characterization of high-surface-area ruthenium oxide (RuO2)/multi-walled carbon nanotubes (MWCNTs) composite electrodes for use in supercapacitors is reported in this work. The RuO2/MWCNTs composites were prepared by the polyol process of RuO2 intoMWCNTsand by Ru annealing in air before mixed with MWCNTs. The chemically oxidized and annealed Ru nanoparti…
a b s t r a c t In this work, poly(amide imide) solutions in dimethylformamide were electrospun into webs consisting of 350nm ultrafine nanofibers. These nanofiber webs were used to produce activated carbon nanofibers (ACNFs), through stabilization and carbonisation–activation processes. Experimental results indicated that ACNFs activated at 800 ◦C afforded the highest specific surface …
Abstract Mesoporous activated carbon samples were prepared from electrospun PAN-based carbon fibers using physical activation with silica. Textural characterization was performed using nitrogen adsorption at 77 K. The BET specific surface area and pore size distribution of silica activated carbon materials were investigated. According to the increment of silica, BET specific surface area was i…

Abstract. Polymer composite electrolytes (PCE) based on poly(ethylene oxide) (PEO) and alkylammoniumfunctionalized clay materials were fabricated. Structural modification and the electrochemical properties were investigated in order to understand the effects of organically modified montmorillonite (OMMT) in the polymer matrix on the ion conductivity. Nanosize layer-structured clay fillers w…
