“…This can be done by oxidization or reduction with an appropriate counter ion 24–26. The presence of alternating single and double bonds along the polymer chain that allows the delocalization and movement of carriers along the backbone 27. When the π‐system in the polymer is partially oxidized or reduced, the conductivity increases by several orders of magnitude.…”

Polythiophene (PT) thin films have been prepared by chemical bath deposition (CBD) method at room temperature (300 K) via oxidative polymerization of thiophene using ammonium peroxodisulfate (APS) as an oxidizing agent. Globular particulates of PT are deposited on the stainless steel and glass substrates. The morphology and chain structure of PT are studied using scanning electron microscopy (SEM) and Raman spectroscopy techniques, respectively. The electrochemical behavior of PT electrode is studied using cyclic voltammetry and galvanostatic chargedischarge studies. PT thin film shows maximum specific capacitance of 300 F g−1 at 5 mV s−1 in 0.1 M LiClO4/PC electrolyte. The asymmetric device formed with PT and graphite shows supercapacitive properties useful in the power applications.

Thiophene (Th), 3-hexylthiophene (3HT) and their nanocomposites with TiO 2 were electropolymerized on Al1050 electrode by chronoamperometic technique. Different concentrations of Th and 3HT homopolymers and their nanocomposites with TiO 2 (2% in total content) were characterized by attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), energy dispersion Xray analysis (EDX) and electrochemical impedance spectroscopy (EIS). The capacitive behaviours of modified electrodes were calculated from Nyquist, Bode-magnitude, Bodephase and Admittance plots. The optimum conditions of capacitive behaviours of homopolymers (PTh and P3HT) and their nanocomposite films of PTh/TiO 2 and P(3HT/TiO 2 ) were electrocoated on an Al1050 electrode by chronoamperometric technique. The anti-corrosion tests for homopolymers and nanocomposite films were examined in 3.5% NaCl solution. The EIS and Tafel extrapolation results were comparatively studied. In all cases, polymer and nanocomposite films have protective behavior of Al1050 against corrosion. P(3HTh)/TiO 2 nanocomposite films gave the highest protection effeciency (PE) = 98% because the amount of defects was much lower than that for the P(3HTh), PTh and PTh/TiO 2 films.

“…Currently, many researchers are interested in tailoring the properties of conducting polymer such as biocompatibility, solubility, electroactivity and antimicrobial to be suited in the biomedical applications . A huge number of study has been carried out focusing on antimicrobial properties of conducting polymers by incorporating nanoparticles, copolymerisation, functionalisation and composite with other materials including dextran . Antimicrobial activity is important in biomedical application since it has been published that this property is required by polymers to resist bacterial colonisation to be used in medical devices …”

“…This is due to their outstanding fluorescence properties, thermal stability, conductivity and environmental stability that can be used as polymer LEDs, electrical conductors, sensors, solar cells and imaging materials . PT also displays excellent antimicrobial properties after composited with various types of nanoparticle such as CuO and TiO 2 . In addition, Cao et al reported the antimicrobial properties of functionalised PT including poly(sulfobetaine‐3,4‐ethylenedioxythiophene) (PSBEDOT), which demonstrate switchable antifouling/antimicrobial properties.…”

Summary Fluorescent conducting polymer, polythiophene (PT) and PT derivative, poly (3‐hexylthiophene) (P3HT) were synthesised using chemical oxidative polymerisation technique. The polymerisation period for PT were varied to examine the effect of polymerisation time on the properties of PT. PT and P3HT showed interesting characteristics including high fluorescent, whereas the PT synthesised in 3 hours (PT(3h)) has shown antimicrobial properties. The antibacterial activity of PT and PT3HT obtained was evaluated against Bacillus subtilis (B145), Escherichia coli (E266), and Candida albicans (C244). This antibacterial study demonstrated that PT (3h) contains antimicrobial properties on both Bacillus subtilis and Escherichia coli. From the solubility test, PT (3h) and P3HT were further used in the preparation of the composite nano/microfibers with polystyrene (PS) through electrospinning technique. These fibres have the potential to be used in a range of applications that includes antimicrobial materials and sensing.
