| dc.description.abstractEn | In this letter, we report on the enhanced double-layer capacitance of a layered poly (3, 4-ethylene dioxythiophene) PEDOT-MoO3 nanocomposite, which has been synthesized by a novel microwave irradiation method. The x-ray photoelectron spectroscopy analysis shows the changes in electron density and the shift in binding energy suggesting charge transfer from sulfur atoms upon PEDOT intercalation between MoO3 layers. The room-temperature conductivity for the PEDOT-MoO3 composite is found to be 1.82×10−1Scm−1, which is four orders of magnitude higher than that of the pristine oxide (3.78×10−5Scm−1). The enhanced double-layer capacitance of the PEDOT-MoO3 nanocomposite (∼300Fg−1) compared to that (∼40mFg−1) of pristine MoO3 is attributed to higher electronic conductivity, enhanced bidimensionality, and increase in surface area of the nanocomposite. | |
