In this work, the synthesis and comprehensive characterization of a novel binary composite comprising polypyrrole (PPy) protected Y2O3 was fabricated via in situ oxidative-polymerization technique is presented. The investigation primarily focuses on the elucidating the structural, chemical and electrochemical properties of the synthesized composite material to assess its potential applicability as an electrode material in supercapacitors. The structural and bonding aspects of the synthesized sample were examined using advanced analytical techniques, including X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Transmission electron microscopy (TEM) analysis was employed to confirm the synthesis of particles within the nano-range, providing the crucial insights into the morphology and size distribution of the composite. Furthermore, the chemical composition and thermal stability of the composite were evaluated through energy dispersive X-ray and thermogravimetric (TG) analyses, respectively. These analyses contributed to a comprehensive understanding of the material’s composition and stability under different temperature conditions. The electrochemical performance of the PPy-Y2O3 nanocomposite was assessed via cyclic voltametric measurements, revealing a semi-rectangular loop indicative of high surface area and specific conductance. The composite displayed significant charge storage capacity and revealed exceptional ionic and electrical conductivity, highlighting its feasibility for use as an electrode material in supercapacitors. Furthermore, the synthesized PPy-Y2O3 nanocomposite possesses a unique combination of structural integrity, chemical stability and superior electrochemical properties, making it a promising candidate for enhancing the performance of energy storage devices, particularly in supercapacitor applications.

Electroconductive polymers are the materials of interest for the fabrication of electro-conductive tissues. Metal ions through the redox systems offer polymers with electrical conductivity. In this study, we processed a gelatin methacrylate (GelMA) network with gold nanoparticles (GNPs) through a redox system with parahydroxybenzaldehyde (PHB) or curcumin to enhance its electrical conductivity. Induction of the redox system with both PHB and curcumin into the GelMA, introduced some new functional groups into the polymeric network, as it has been confirmed by H-NMR and FTIR. These new bonds resulted in higher electro-conductivity when GNPs were added to the polymer. Higher electroactivity was achieved by PHB compared to the curcumin-induced redox system, and the addition of GNPs without redox system induction showed the lowest electroactivity. MTT was used to evaluate the biocompatibility of the resultant polymers, and the PHB-treated hydrogels showed higher proliferative effects on the cells. The findings of this study suggest that the introduction of a redox system by PHB in the GelMA network along with GNPs can contribute to the electrochemical properties of the material. This electroactivity can be advantageous for tissue engineering of electro-conductive tissues like cardiac and nervous tissues. Graphical Abstract
