“…Conducting polymers [1] have attracted attention because of their potential applications in different fields such as supercapacitors [2], sensors [3], photovoltaic cells [4], electrochromic devices [5], organic light-emitting diodes [6], and actuators [7]. Significant progress has been made in increasing the conductivity, stability and processability of conducting polymers.…”

a b s t r a c tElectrochemical copolymerization of pyrrole (Py) and 3,4-ethylenedioxythiophene (EDOT) was performed in an ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate, (BMIM BF4) employing a 'micro-cell' in order to use the materials efficiently. Characterization of the copolymers formed on an ITO substrate was performed for different Py: EDOT ratios (1:2, 1:1, 2:1) in both aqueous and ionic liquid electrolytes. The three copolymers displayed different absorbance spectra with max of the polaron species at 507, 540 and 580 nm for PPy-co-PEDOT ratios of 1:2, 1:1, 2:1, respectively. Electrochemical and spectroelectrochemical analysis revealed that the properties of the copolymer depend upon the Py/EDOT monomer ratio used. The copolymer PPy-co-PEDOT (2:1) displayed good stability, a switching time of 20 s and a colouration efficiency of 101.3 C-1cm2. The presence of Py in the copolymer stabilised the polaron state of the copolymer and allowed greater ion mobility compared to the PEDOT alone.

“…They represent a 'green' alternative to many traditional electrolytes [18]. ILs containing anions such as NTF 2 , BF 4 and PF 6 have large electrochemical windows of stability which can go over + 2 V vs Ag/Ag + in the oxidation region and below Li/Li + potential in the reductive region [18].…”

“…Polyaniline (PAni) is an example of a well-studied conducting polymer which has been investigated for a diverse range of applications [3][4][5][6][7] including as the active material for biological and chemical sensing applications [8][9][10][11]. PAni can be chemically (or electrochemically) switched reversibly between two or more redox states [12].…”

“…CNTs have previously been combined with both bulk and nano PAni to improve its properties for a range of applications, including actuation and sensing [4,6,[30][31][32][33][34][35][36][37][38][39][40]. For example, Spinks et al report using CNTs to improve the tensile strength and stress loading of PAni for artificial muscles [6].…”

“…However, the electrochemical method to prepare polyaniline is limited in terms of mass production [7,8]. In spite of the fact that chemical polymerisation is easier than the electrochemical one [32], composites from carbon and chemically polymerised polyaniline was rarely studied and most of them use carbon nanotubes [6-9, 32, 33]. Very little work has been done dealing with activated carbon and chemically polymerised polyaniline [34,35].…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. The second method (polymerization over carbon) using a thermally treated carbon seems to be the best one since a more porous (or thinner) polyaniline film is produced.
