We develop a fast and cost effective method for the fabrication of a nanocomposite supercapacitor electrode. In this study aluminum foils were decorated with vertically aligned carbon nanotubes (VACNT) via chemical vapor deposition (CVD) method, which was followed by the electrodeposition of polyaniline (PANI) layer on top of the VACNTs. Electrochemical behavior of the fabricated nanocomposite electrodes were evaluated through cyclic voltammetry, galvanostatic charge discharge cycles and electrochemical impedance spectroscopy method. Fabricated VACNT/PANI nanocomposite electrodes through 15 electrodeposition cycles showed significant electrochemical performance. The specific capacity of these electrodes was calculated as 16.17 mF/cm(2) at a current density of 0.25 mA/cm(2). (C) 2018 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.

Ternary nanocomposite SWNT/WO3/PANI thin film electrodes for supercapacitors
Yuksel, Recep; Durucan, Caner; Ünalan, Hüsnü Emrah (2016-02-15)
We describe a simple and fast process for the fabrication of ternary nanocomposite supercapacitor electrodes. In this work, thin film supercapacitor electrodes made up of binder-free single walled carbon nanotube (SWNT) thin films were deposited onto glass substrates by vacuum filtration followed by stamping method. Next, tungsten oxide (WO3) and polyaniline (PANI) were electrodeposited on the SWNT thin films. Combination of SWNTs and pseudocapacitive WO3 and PANI created a synergistic and complementary eff...
Cobalt Oxide Nanoflakes on Single Walled Carbon Nanotube Thin Films for Supercapacitor Electrodes
Durukan, Mete Batuhan; Ünalan, Hüsnü Emrah (2016-12-20)
We demonstrate a simple and cost-effective approach for the fabrication of cobalt oxide (Co3O4) nanoflakes on single walled carbon nanotube (SWNT) thin films for supercapacitor electrodes. SWNT thin films are prepared by vacuum filtration and consecutive stamping method onto which cobalt hydroxide (Co(OH)(2)) nanoflakes are electrodeposited and annealed to obtain Co3O4. A gravimetric capacitance of 313.9 F.g(-1), corresponding to an areal specific capacitance of 70.5 mF.cm(-2) is obtained from the fabricate...
Flexible supercapacitor electrodes with vertically aligned carbon nanotubes grown on aluminum foils
Dogru, Itir Bakis; Durukan, Mete Batuhan; Turel, Onur; Ünalan, Hüsnü Emrah (2016-06-01)
In this work, vertically aligned carbon nanotubes (VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition (CVD) method. Solution based ultrasonic spray pyrolysis (USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor...
Transparent and Flexible Supercapacitors with Single Walled Carbon Nanotube Thin Film Electrodes
YÜKSEL, Recep; SARIOBA, Zeynep; Çırpan, Ali; Hiralal, Pritesh; Ünalan, Hüsnü Emrah (2014-09-10)
We describe a simple process for the fabrication of transparent and flexible, solid-state supercapacitors. Symmetric electrodes made up of binder-free single walled carbon nanotube (SWCNT) thin films were deposited onto polydimethylsiloxane substrates by vacuum filtration followed by a stamping method, and solid-state supercapacitor devices were assembled using a gel electrolyte. An optical transmittance of 82% was found for 0.02 mg of SWCNTs, and a specific capacitance of 22.2 F/g was obtained. The power d...
Coaxial silver nanowire network core molybdenum oxide shell supercapacitor electrodes
Yuksel, Recep; Coskun, Sahin; Ünalan, Hüsnü Emrah (Elsevier BV, 2016-03-01)
We present a new hybrid material composed of molybdenum (IV) oxide (MoO2) shell on highly conducting silver nanowire (Ag NW) core in the network form for the realization of coaxial Ag NW/MoO2 nanocomposite supercapacitor electrodes. Ag NWs were simply spray coated onto glass substrates to form conductive networks and conformal MoO2 layer was electrodeposited onto the Ag NW network to create binder-free coaxial supercapacitor electrodes. Combination of Ag NWs and pseudocapacitive MoO2 generated an enhanced e...
