Silver Nanowire/Conducting Polymer Nanocomposite Electrochromic Supercapacitor Electrodes

Color-changing energy storage devices that can easily communicate with the user carry the potential to be integrated into smart electronics. In this work, nanocomposite electrochromic supercapacitor electrodes were fabricated with silver nanowire (Ag NW) network electrodes and a green to transmissive electrochromic polymer, PDOPEQ. High transparency and conductivity of Ag NW network current collectors allowed the fabrication of electrochromic supercapacitors and investigation of the spectroelectrochemical and electrochemical properties of the PDOPEQ. Previously reported electrochromic properties such as long term electrochromic switching stability and vibrant color change for PDOPEQ were well transferred into electrochromic capacitors. Investigated electrochromic supercapacitors changed their color from vibrant green to transparent with superior characteristics. Specific capacitance of the fabricated nanocomposite electrodes was calculated as 61.5 F g(-1) at a current density of 0.1 A g(-1) and to the best of our knowledge, one of the highest capacity retention value was obtained upon 20000 galvanostatic charge-discharge cycles. With these color options and electrochemical performance, investigated conducting polymer (CP) holds strong promise to be used in electrochromic supercapacitors. (C) 2017 The Electrochemical Society.

The need for determining the instant capacity of an energy storage device has led to the integration of an indicator gauge in batteries. Consumers only have to press the contact points on the battery to activate a thermochromic indicator, which measures the heat resistance of the device. This can be implemented in a supercapacitor through electrochromism, eliminating the necessity to press on the contact points. With this motivation, here we report on the fabrication and characterization of all-organic mult...

A simplemethod for the fabrication of stable and highly active surface enhanced Raman scattering (SERS) substrate by exploiting the optical properties of the silver nanoparticles (AgNPs) and organizational characteristics of the polymer is presented. Homogeneous distribution ofAgNPs is achieved with the usage of poly (4,7-di-2,3-dihydrothieno [3,4-b] [1,4] dioxin-5-yl-2,1,3 benzoselena diazole) (PESeE) film coated on the indium tin oxide glass (ITO) surface. The obtained structure ensured the emergence of a...
Metamaterial Absorber Based Multifunctional Sensors
Sabah, Cumali (The Electrochemical Society, 2016-01-01)
In this paper, several important applications of a metamaterial absorber (MA) based sensors such as temperature, pressure, moisture, and density are presented. Since the sensing ability mostly considers the resonance frequency, the frequency range where the resonance shifts occur linearly or non-linearly depending on the temperature, pressure, moisture, and density changes is selected carefully. The model is composed of X shaped resonators (XSR), dielectric substrate, the sensing layer, dielectric substrate...

Graphene has incredible carrier transport property with high application opportunity at single molecule level, which composes it as promising materials on nano electronic application. In order to develop the new device such as graphene nanoribbon transistor, Carbon Nanotube Field Effect Transistor (CNTFET) and nanowire based devices, it is essential to investigate the quantum limit in low dimensional systems. In this paper transmission coefficient of the schottky structure in the graphene based transistor i...

We propose a design of a metamaterial based sensor to be used in various applications including micro-fluid, strain and rotation sensing. The structure has a simple geometry composed of a single circular split ring resonator (CSRR) and it is possible to adjust the resonance frequency in the region of desired band. The resonance frequency is carefully selected so that the materials to be sensed have linear dielectric curves at that particular frequency range which iscrucial to design accurate sensing charact...
