Abstract:

In this dissertation, several new tools for making neurochemical measurements are presented. All of the technologies developed here include the conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), as a sensing platform. PEDOT is ideal for inclusion in neurochemical sensors because it is inexpensive, easily processed and patterned, biocompatible, and, conductive. A synthesis of low-capacitance PEDOT:Tosylate enables electrochemical measurements of neurotransmitters with scan rates of 100 V/s. This material was further characterized to determine the unique molecular properties that

Abstract:

<p>All conducting polymers are potentially electrochromic, owing to the injection of charge carriers that changes their electronic structure and results in a shift of their optical absorption towards higher wavelengths. PEDOT-PSS and PEDOT-S are very promising materials in terms of electrochromic properties, due to the good contrast existing between their doped and undoped forms. However this contrast has to be enhanced in order to design more efficient electrochromic devices, and new solutions should thus be found in order to solve this issue.</p><p>Surface plasmons are described as electroma

Abstract:

The emergence of a new class of polymer, namely conducting polymers (CPs) in late 1970s, has attracted many hysicists, chemists and materials researchers to study them in depth due to the unique properties and broad applications of this material. Poly(3,4-ethylenedioxythiophene) (PEDOT) has been found to be the most chemically stable CP to date. The aim of this project was to characterise PEDOT and its derivatives for applications in ion sensing. In this work, PEDOT and its derivatives i.e. poly(3,4-propylenedioxythiophene) (PProDOT) and poly(3,3-dibenzyl-3,4-propylenedioxythiophene) (PDBPD) d

The finest features are produced by X-ray or electron-beam methods, both of which are very expensive to employ. Less expensive methods use ultraviolet (UV) light to expose the photoresist through a photomask. The resol

Poly(3,4-ethylenedioxythiophene), PEDOT, belongs to the group of conducting polymers and is characterized by its high stability, a moderate band gap and its optical transparency in the conductive state.

Thus, this work focuses on the development of conductive particles by preparing composite structures.

Abstract:

Questo lavoro di ricerca si concentra sulla sintesi e la caratterizzazione di nuovi complessi ciclopentadienonici di Fe0 con leganti carbenici N-eterociclici e sullo studio delle loro proprietà come mediatori redox negli Elettrodi Chimicamente Modificati. Nello specifico, si sono sintetizzati due complessi di Fe legati tramite il carbene NHC ad un monomero di EDOT e poi sono stati elettropolimerizzati sulla superficie di elettrodi di vetro modificato. I sensori così ottenuti sono stati caratterizzati con varie tecniche e testati nella rivelazione di metanolo e glucosio. Sulla base di prove di

Poly(3,4-ethylendioxythiophen) (PEDOT) ist ein Kunststoff der zur Gruppe der intrinsisch leitfähigen Polymere (ILP) zählt. Aufgrund seiner chemischen und thermischen Stabilität findet er Verwendung in antistatischen Verkleidungen und als Elektrodenmaterial. PEDOT (und andere ILP) zeigen aufgrund ihrer Schaltbarkeit zwischen (reduzierten, ) neutralen und oxidierten Zuständen unterschiedliche Eigenschaften wie Leitfähigkeit, Farbe oder Viskoelastizität. Im Rahmen dieser Arbeit wurden die elektrochemischen und viskoelastischen Eigenschaften von PEDOT-Filmen untersucht. Dabei wurde die Quarzmikrow

Detection of chemicals is a vital part of chemistry. For this reason, many detection systems are developed by scientists and every detection system has its own advantages. Raman spectroscopy is one of these detection systems having many advantages. However, this technique suffers from low signal intensity disadvantage.

We observed the conductivity by using 4-points probe, to be 4.29×10-3 S/cm for sample containing 20 phr of PEDOT. We found the compatibility is not good from DSC and TGA determinations.
