“…[1, 2, 3, 4, 5, 6, 7, 8]. The conjugated conducting polymers and their copolymers exhibit sufficiently high optoelectronic properties, generally used in low-cost electronic and optical devices [9]. For the effective performance, most of the above said solid-state devices have been based on the conjugated conducting polymers such as polythiophene (PTh) and polyindole (PIn) due to their excellent electrical characteristics, thermal and environmental stability and solubility [10, 11, 12].…”

In this contest, a novel series of random thiophene-indole (Th-In) conducting copolymers have been synthesized through oxidative copolymerization of their monomers in aqueous medium at room temperature using anhydrous ferric chloride (FeCl 3 ) as an oxidant. The structure of as-studied samples have been confirmed through X-ray diffraction (XRD) technique. Field emission-scanning electron microscopy (FE-SEM) ensured the morphology of as-prepared copolymers. The complex optical parameters of the samples have been estimated through ultraviolet-visible (UV-Vis) spectroscopy. The temperature dependence of dc electrical conductivity of the samples have been obtained over a temperature range 303–393 K, which found to be in the range 10 −6 –10 −4 Scm −1 followed Arrhenius relation. The degradation behaviour has been studied through thermogravimetry (TG) and differential thermal analysis (DTA) techniques.

In this work, a novel approach was employed to prepare and utilize lead (II) oxide and poly(aniline-co-thiophene) (PANI-co-PTh) composite materials as electrode materials for supercapacitors, marking the first instance of such utilization in the literature. PANI-co-PTh was synthesized in bulk through chemical polymerization, and the conducting polymers underwent comprehensive spectroscopic, physical, and microscopic characterization. Subsequently, the material, incorporating lead (II) oxide (PbO) as a composite, was employed as electrode materials in asymmetric-type supercapacitors. The main results indicate a clear relationship between the surface area of conducting polymers and their specific capacitance. Notably, PANI-co-PTh-6, possessing the highest surface area, demonstrated the highest specific capacitance. Particle size distribution and specific surface area for PANI-co-PTh-6 were determined as 130 μm and 64.76 m2g−1, respectively. The PbO@PANI-co-PTh-3 configuration exhibited the highest specific capacitance, reaching 294 Fg−1 at a 10 mVs−1 scan rate. Remarkably, during long-cycle experiments, this system demonstrated a capacity retention of 70.69% after 1000 cycles. The inaugural application of the PbO@PANI-co-PTh-3 supercapacitor showcased notable capacitance values, establishing a substantial foundation for future research endeavors in this field.

Linear alkyl-benzene sulfonate surfactants (LAS) are a major pollutant source of sewage and wastewater. They trigger severe impact on the environmental fauna and flora. Current research explores the synthesis of three different core–shell nanocomposites (CSNCs) containing titania through an inexpensive oxidative polymerization technique. The fabricated CSNCs were evaluated for the photocatalytic degradation of LAS water contaminations. The selected CSNCs investigated for this study were the TiO2/poly(aniline-co-pyrrole) and TiO2/ poly(aniline-co-3-Me-thiophene) as well as the TiO2/terpolymer (aniline-pyrrole-m-aminobenzoic acid). The structure of the formed nanocomposites was confirmed by varied characterization spectroscopy. The core–shell structure of the nanocomposites was confirmed by scanning electron micrographs and transmission electron microscopy. The CSNCs exhibited intensive photo catalytic degradation efficacy toward LAS under visible light exposure in comparison with the exposure in their absence. The parameters optimizing their photovoltaic degradation efficiency were assessed. The presented approach implies that an effective, economical, and environmentally friendly synthetic setup was achieved to produce novel CSNCs with high potential as LAS photodegradation agents.
