Studies on conducting polymers : the synthesis and anodic electropolymerisation of novel B-functionalised thiophenes
… [9] were synthesised as precursors for anodic electropolymerisation though an anticipated 2,5 ’-coupling of their respective thiophene moieties. The spectroscopic properties of these novel compounds, including their electrochemical behaviour, are presented.

Developing polypyrrole coated coronary stents for extended release of Sirolimus
… relevant period of time. Electrochemical electropolymerisation technology was used to produce a series of poylyrrole coatings on stainless steel wires. Different voltages were used during the potentiostatic electropolymerisation process. Then the coated wires were immersed in different …

Bioactive surfaces for improved coronary stent performance
… can be deposited onto metal surfaces through electropolymerisation, a process that may be superior to the spray coating techniques commonly used by stent manufacturers. However, the full potential of this approach for use in stent coatings remains to be determined. An anti-inflammatory agent, …

Electroactive Conjugated Polymers as Charge-Transport Materials for Optoelectronic Thin-Film Devices
… polymerised on platinum electrodes by reductive electropolymerisation. However, a reductive polymerisation was not possible for the borane monomer 19 which is thought to be due to a strong localisation of the unpaired electron on the central boron atom of the radical anion. An …

Electrochemical synthesis of polyesters and polyamides. A study of the polymerisation of lactams, lactones and the anhydride/propylene oxide system by direct electrolysis of their conducting solutions
… investigation into the kinetics and mechanism of electropolymerisation of E-caprolactone in DMF and using LiCl or KNO3 as supporting electrolyte was undertaken. In the case of both supporting electrolytes it was found that the initial rate of polymerisation was directly proportional to the initial …

Novel strategies for optimising drug release from medicinal implants
… by either potentiostatic or cyclic voltammetry electropolymerisation. The surface characteristics of these coatings was then determined using Scanning Electron Microscopy. Finally, the coatings were immersed in physiological solution and salicylate release quantified at various time points up to …

Development and characterisation of macro-disc and micro-band electrodes for electrochemical sensing applications
… a platinum modified gold microband electrode by electropolymerisation with an o-phenylenediamine/ß-cyclodextrin layer. The resulting microband biosensor demonstrated on-chip glucose detection in buffer based media. When applied to foetal bovine serum the sensor displayed a reduced sensitivity. …

Electrochemical synthesis and characterisation of polypyrrole/chitosan films doped with molecular anions
… was cast on to the doped polypyrrole post electropolymerisation and then cured under an infrared lamp. This was found to be more suitable for incorporating larger anionic species. A comprehensive electrochemical characterisation of the polypyrrole-chitosan composite films was obtained using …

The development of multisensor arrays utilising conducting polymers.
… investigation of the variables involved in the electropolymerisation protocols, and expansion of the sensing chemiresistors available. This was achieved by analysis of polymer fabrication methods, and the variation in monomer and electrolyte feedstocks used during polymerisation. Polymer film …

Electronic evaluation of organic semiconductors towards electronic devices
… organic electronic devices by employing electropolymerisation to form a PEDOT/PEDTT bi-layer. The fabricated device did not exhibit any distinctive photo-response when it was assessed in a diode configuration. This was due to inefficient charge separation at the donor- acceptor interface.

The Formation and Characterisation of a Polypyrrole Based Sensor for the Detection of Urea
… was incorporated into the polymer film during electropolymerisation from an aqueous solution of pyrrole monomer, BSA and NaCl as a supporting electrolyte. The presence of the BSA within the polymer film was confirmed using cyclic voltammetry, electrochemical impedance spectroscopy and scanning …
