This study presents an experimental investigation with a comparative analysis on the photocatalytic activity of two composites, namely poly(vanillin‐co‐pyrrole)/ZnO and poly(vanillin‐co‐pyrrole)/TiO2, for the degradation of methylene blue (MB) dye under simulated solar irradiation. Conductive polymers, specifically poly(vanillin‐co‐pyrrole) (PPHMB) and its derivatives, were employed as photosensitizers to enhance the photocatalytic activity of ZnO and TiO2 under solar irradiation. PPHMB was synthesized using the cationic polycondensation method, while the PPHMB/ZnO and PPHMB/TiO2 composites were prepared through the co‐precipitation method. The prepared composites exhibited superior photocatalytic activity compared to bare ZnO and TiO2 under solar irradiation for the degradation of MB dye. Extensive characterization techniques, including Fourier‐transform infrared, x‐ray diffraction, thermogravimetric analysis, and optical analysis, were employed to investigate the properties of the composites. Various influential operational parameters such as initial dye concentration, irradiation time, and the dosage of PPHMB/ZnO and PPHMB/TiO2 composites were systematically studied to evaluate their effects on photocatalytic degradation. The optical density of dye degradation was quantified using a UV–Visible spectrophotometer, while the repeatability of the photocatalytic activity was rigorously assessed.

Polymer networks incorporated with iron and zinc oxide nanoparticles have superparamagnetic and electrical characteristics where it can be employed in a variety of significant applications. To achieve optimal distribution and connection of nanoparticles in various polymeric matrices, it is required to investigate their dispersion performance with varied contents and the impact on their physical characteristics. A controlled sol-gel method is used combined with gel casting to synthesize organic-inorganic nanocomposites of (ZnO)x(1 − x)Fe2O3 loaded within a polystyrene-polyethylene glycol matrix. The structural and morphological assembly of the hydrogen bonds between the inorganic and organic parts is verified using X-ray diffraction (XRD) and scanning/transmission electron microscope (SEM/TEM) for the synthesized nanocomposites. The existence of the Fe aggregates, Zn/Fe pairs, and organic molecules was also confirmed by FTIR spectra. Optical and magnetic properties were evaluated. The band gap, refractive index, optical dielectric constant, and optical electronegativity were extracted.

The Conducting of polymers belongs to the class of polymers exhibiting excellence in electrical performances because of their intrinsic delocalized π- electrons and their tunability ranges from semi-conductive to metallic conductive regime. Conducting polymers and their composites serve greater functionality in the application of strain and pressure sensors, especially in yielding a better figure of merits, such as improved sensitivity, sensing range, durability, and mechanical robustness. The electrospinning process allows the formation of micro to nano-dimensional fibers with solution-processing attributes and offers an exciting aspect ratio by forming ultra-long fibrous structures. This review comprehensively covers the fundamentals of conducting polymers, sensor fabrication, working modes, and recent trends in achieving the sensitivity, wide-sensing range, reduced hysteresis, and durability of thin film, porous, and nanofibrous sensors. Furthermore, nanofiber and textile-based sensory device importance and its growth towards futuristic wearable electronics in a technological era was systematically reviewed to overcome the existing challenges.
