“…Abacı et al . could not detect S using elemental analysis in the polymer mixture when the thiophene amount was lower than 5/3 in an aniline/thiophene mol ratio . The conversions (%) of aniline and thiophene monomers were also calculated from the elemental analysis results of each PAn–PTh/PET composite and PAn–PTh polymers having different aniline/thiophene mol ratios.…”

“…Moreover, the conductivity of PTh containing composites is more stable with respect to various environmental conditions such as washing processes . In the literature, there have been various studies reporting the usage of both PAn and PTh polymers for various purposes by electrochemical copolymerization of aniline and thiophene but their composites with textile materials have not been prepared by chemical oxidative polymerization …”

A conductive polyaniline (PAn)-polythiophene (PTh)/poly(ethylene terephthalate) (PET) composite fiber was prepared by polymerization of aniline and thiophene in the presence of PET fibers in an organic medium with FeCl 3 . The effects of polymerization conditions, such as polymerization medium, mol ratios of aniline/thiophene and FeCl 3 /aniline-thiophene as well as polymerization temperature and time, were investigated on PAn-PTh content (%) and surface resistivity of the composite. The composite with the lowest surface resistivity (1.30 MX/cm 2 ) was obtained by polymerization of aniline and thiophene (1/3 mol ratio) in acetonitrile/ chloroform (1/5 volume ratio) at 20 C. The surface resistivity of the PAn-PTh/PET composite containing 4.8% PAn-PTh was increased from 1.9 MX/cm 2 to 270 MX/cm 2 at pH 11. The washing durability of the composites was determined with domestic and commercial laundering processes by monitoring the surface resistivity and morphology. The composite was also characterized with FTIR, TGA, elemental analysis, optic microscope and SEM techniques.

“…[ 9 ] Copolymers of aniline, such as butyl thioaniline [ 32 ] and pyridine‐thiophene based copolymer [ 33 ] are reported and show a noticeable decrease in band gap or increase in conductivity when compared to their respective homopolymers. [ 34 ] PANI and polythiophene both are well established as conducting polymers and are extensively studied. [ 6 ] In an endeavor to improve the conducting properties of these polymers, copolymerization of aniline and thiophene has been explored as one of the processes.…”

Doped polyaniline (PANI), doped polythiophene and their copolymers (by interfacial and aqueous polymerization) with monomers at 50:50 ratio has been synthesized and are characterised by X-ray diffraction (XRD), thermo gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) measurements. The copolymer synthesized by interfacial polymerization is mixed with copper oxide nanoparticle synthesized chemically in lab at 0.2% loading. XRD measurement showed no peak for PANI and polythiophene, which confirms amorphous structure of the two. However, clear peak for copper oxide nanoparticle at 2θ = 36.45 and multiple peaks for the copolymer (interfacial polymerization) and the copolymer Nanocomposite signifies crystalline structure. TGA results show that the stability of copolymer prepared by interfacial polymerization lies in between the PANI and polythiophene. FTIR spectroscopy confirms that both aniline and thiophene units are present in the interfacial copolymer. Further the monomers are chemically linked in the copolymer (by interfacial and aqueous polymerization). The presence of peak at about 1103 cm −1 confirms the formation of N S bonding by reaction in between aniline and thiophene in the interfacial copolymer. The uniform distribution of nanoparticles in copolymer (interfacial polymerization) matrix have been confirmed from TEM images. The electrical properties of polymers, copolymers and copper oxide Nanocomposite are studied from which it is found that the copolymer have a synergistic effect on the improvement of conductivity when compared with the individual polymers. The 0.2% loading of copper oxide nanoparticles further improves the conductivity of the interfacial copolymer by approximate 15.24-fold.

“…CP-based heterocycles such as polyaniline (PANI) or polythiophene (PTH) have been extensively studied because they exhibit interesting electrochemical properties [7,[10][11][12][13][14], including ease of doping or, in the case of PANI, excellent redox resistance [15,16]. Likewise, among the CPs, PTH has been considered a model concerning charge transfer as it possesses good stability under ambient conditions in its doped and undoped state [17].…”

Synthesis and characterization of aniline and thiophene and/or alkylthiophenes polymers

Three new polymers, obtained by reacting thiophene or 3-alkylthiophenes as electron donors with aniline as acceptor in a donor-acceptor structure, were synthesized via oxidative polymerization using iron(III) chloride (FeCl 3 ). The final products were characterized utilizing conventional techniques such as IR, NMR, UV-Vis spectrometry, which enabled demonstrating that an increase of the aliphatic chain length causes significant solubility increase of the system, without modifying the conductivity. On the other hand, observed an important variation of the thermal stability of the polymer when medium-length aliphatic chains were inserted was observed; in contrast, the addition of a methyl group (short chain length) hardly affected the mentioned properties.
