Spongy-Network-like Polyaniline Thin Films as Electrodes for a Supercapacitor

Graphene/polyaniline woven fabric composite films as flexible supercapacitor electrodes.

We report the design and preparation of graphene and polyaniline (PANI) woven-fabric composite films by in situ electropolymerization. The introduction of PANI greatly improves the electrochemical properties of solid-state supercapacitors which possess capacitances as high as 23 mF cm(-2), and exhibit excellent cycling stability with ∼ 100% capacitance retention after 2000 cycles. The devices h...

A "skeleton/skin"strategy for preparing ultrathin free-standing single-walled carbon nanotube/polyaniline films for high performance supercapacitor electrodes

Doped Zinc Oxide Thin Films as Transparent Conductive Electrodes

Sn doped ZnO thin films have been deposited on c-cut sapphire single crystal substrates at 200°C by pulsed electron beam deposition. The kinetic energies of the ions in the plasma plume determined from ion probe measurements, present a relatively broad distribution of the energies from a few eV to one hundred eV. Sn doped ZnO films have a graded composition, with a slightly in-depth variation o...

Oxidative chemical vapor deposition of polyaniline thin films

Polyaniline (PANI) is synthesized via oxidative chemical vapor deposition (oCVD) using aniline as monomer and antimony pentachloride as oxidant. Microscopy and spectroscopy indicate that oCVD processing conditions influence the PANI film chemistry, oxidation, and doping level. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray photoelectron spectroscop...

Ag/Biochar Composite for Supercapacitor Electrodes L.Kouchachvili

The development of new electrical energy storage devices and the improving of existing ones e.g. batteries and supercapacitors (SC) has become extremely important due to increased application of these devices in transportation and in renewable energy storage. Among them, SC are more capable of generating higher power density than are batteries, and are gaining particular interest. They are used...
