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 density can reach to 41.5 kW.kg(1) and shows good capacity retention (94%) upon cycling over 500 times. Fabricated supercapacitors will be relevant for the realization of transparent and flexible devices with energy storage capabilities, displays and touch screens in particular.

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...
Textile supercapacitors-based on MnO2/SWNT/conducting polymer ternary composites
Yuksel, Recep; Ünalan, Hüsnü Emrah (2015-12-01)
This paper describes a simple and fast process for the fabrication of flexible and textile-based supercapacitors. Symmetric electrodes made up of binder-free ternary composites of manganese oxide (MnO2) nanoparticles, single walled carbon nanotubes (SWNT) and a conducting polymer (either polyaniline (PANI) or poly(3,4-ethylenedioxythiophene)-poly( styrenesulfonate) (PEDOT: PSS)) were layer-by-layer deposited onto cotton substrates by dip coating method. Solid-state supercapacitor devices were assembled usin...
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...
Vertically aligned carbon nanotube - Polyaniline nanocomposite supercapacitor electrodes
Aydınlı, Alptekin; Ünalan, Hüsnü Emrah (2018-10-04)
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 imp...
Mechanical and optical properties of SiO2 thin films deposited on glass
Simurka, Lukas; Ctvrtlik, Radim; Tomastik, Jan; Bektaş, Gence; Svoboda, Jan; Bange, Klaus (2018-09-01)
The optical and mechanical properties of amorphous SiO2 films deposited on soda-lime silicate float glass by reactive RF magnetron sputtering at room temperature were investigated in dependence of the process pressure. The densities of the films are strongly influenced by the process pressure and vary between 2.38 and 1.91 g cm(-3) as the pressure changes from 0.27 to 1.33 Pa. The refractive indices of the films shift between 1.52 and 1.37, while the residual compressive stresses in the deposited films vary...
