Abstract:
Abstract <strong>Objectives:</strong>&nbsp;This research serves to explore the dynamic interaction between &gamma;-radiation and PVA-PTh (Polyvinyl alcohol-Polythiophene) composite films with the intent to revolutionize the field of rechargeable batteries. The objective of this study is synthesis of PVA-PTh films and to comprehend the impacts of &gamma;-radiation at various dosage rates with greater emphasis to their electrical characteristics.&nbsp;<strong>Methods:</strong>&nbsp;Our methodology encompasses the application of a chemical oxidative technique to form PVA-PTh nanocomposite films, followed by an enlightening analysis through SEM, FTIR, AAS, and electrical conductivity measurements after &gamma;-radiation. The fascinating outcomes extend beyond the lab, with the PVA-PTh composite films and their &gamma;-radiated counterparts venturing into the realm of battery development.&nbsp;<strong>Findings:</strong>&nbsp;The results unveiled are captivating. SEM analysis reveals the emergence of smaller, intricately structured flakes in &gamma;-radiated PVA-PTh composite films, indicating significant morphological changes. FTIR results showcase shifts and new absorption bands at 788 cm-1 and 1031 cm-1, evidence of chain crosslinking and scission processes triggered by &gamma;-radiation. Surprisingly, although this radiation reduces the iron (Fe) ion content in PVA-PTh films, the electrical conductivities remain unwavering, even when exposed to 30 kGy (kilo Grays) dose. This steadfastness extends to consistent open circuit voltage (Voc) of 0.30 volts, which persists for astonishing duration of approximately 35 minutes in PVA-PTh conducting films. This exceptional stability paves the way for integration of films into cutting-edge polymer battery systems.&nbsp;<strong>Novelty:</strong>&nbsp;This research unlocks opportunities for innovative applications, invites further exploration across diverse fields by providing groundbreaking insights into the morphology, chemical composition, electrical behavior of PVA-PTh composite films. The exceptional stability of electrical conductivity in &gamma;-radiated PTh samples, even under the harshest radiation conditions, offering testament to their reliability and resilience. These results point towards modern polymer battery systems with consistent Voc and enduring current flow, supporting the PVA-PTh composite films in battery applications. <strong>Keywords:</strong>&nbsp;PTh; &gamma;-radiation; Polythiophene; PVA-PTh; Battery &nbsp;

Abstract:
Abstract In this study, polythiophene/Al2O3 (PTh/Al2O3) and polyaniline/Al2O3 (PAn/Al2O3) nanocomposites in the presence of poly(vinyl alcohol) (PVA) as the surfactant were synthesized via in situ chemical oxidative polymerization method in aqueous medium. The synthesized nanocomposites were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Results indicated that the Al2O3 and poly(vinyl alcohol) influenced the properties of synthesized nanocomposites. The aim of this research was to investigate the sorption characteristics of polythiophene and polyaniline nanocomposites for the removal of heavy metal cations including Pb(II), Zn(II) and Cd(II) from aqueous solution. The factors that affected the adsorption equilibrium as well as the removal efficiency of the nanoadsorbents, i.e., contact time, metal ion concentration, pH and adsorption conditions were investigated in detail. From the kinetic results, it was concluded that the pseudo-second-order kinetic model was found to be the best at describing the adsorption process for Pb(II), Zn(II) and Cd(II) on PTh-PVA/Al2O3 and PAn-PVA/Al2O3. In addition, thermodynamic analysis suggests the endothermic and spontaneous nature of the present adsorption process with increased entropy on PTh-PVA/Al2O3 and PAn-PVA/Al2O3. The results suggest polythiophene, polyaniline and their nanocomposites have great potential to be used as efficient absorbent for the removal of heavy metal ions from water.

Abstract:
Supercapacitors are widely used in various fields due to their high power density, fast charging and discharging speeds, and long service life. However, with the increasing demand for flexible electronics, integrated supercapacitors in devices are also facing more challenges, such as extensibility, bending stability, and operability. Despite many reports on stretchable supercapacitors, challenges still exist in their preparation process, which involves multiple steps. Therefore, we prepared stretchable conducting polymer electrodes by depositing thiophene and 3-methylthiophene on patterned 304 stainless steel (SS 304) through electropolymerization. The cycling stability of the prepared stretchable electrodes could be further improved by protecting them with poly(vinyl alcohol)/sulfuric acid (PVA/H2SO4) gel electrolyte. Specifically, the mechanical stability of the polythiophene (PTh) electrode was improved by 2.5%, and the stability of the poly(3-methylthiophene (P3MeT) electrode was improved by 7.0%. As a result, the assembled flexible supercapacitors maintained 93% of their stability even after 10,000 cycles of strain at 100%, which indicates potential applications in flexible electronics.
