The purpose of this research is to develop advance conducting material blended with metal oxides that held both conducting and antimicrobial properties and due to this, applicable in many biomedical fields. The synthesis of nanoparticles of copper oxide (CuO) is performed by the chemical co-precipitation method and the synthesis of pure polyaniline (PANI) and PANI-CuO nanocomposites were performed by using in-situ chemical oxidative synthesis. The structural analysis was carried out by Xray diffraction (XRD) studies, Fourier transform infrared spectroscopy (FTIR), and Ultraviolet -Visible (UV-Vis) absorption spectrometry. The peaks obtained in spectra validate the fabrication of desired materials. The average particle size of synthesized materials was calculated using the Debye Scherrer formula, which was found in the nanoscale range. The scanning electron microscope (SEM) images explored the morphology of CuO and PANI-CuO composite. The direct current (DC) conductivity measurement of samples was performed by the four-probe method for various temperatures. The values showed an increase of electrical conductivity in the composite as compared to PANI and supported the metallic nature of the composite. The antibacterial activity of composites was performed by disk diffusion method using Bacillus subtilis (Gram + ve bacteria) and Escherichia coli (Gram-ve bacteria) and the results are encouraging.

Mixed metal nanocomposites encapsulated with conducting polymer plastic may show synergistic effects in their properties resulting in unique applications in optoelectronic, conducting material, recording tapes, data‐storing quantum dots, catalysis, sensors, adsorption, purification, seperation, biosensors, antibacterial, and anti‐corrosive agents. Encapsulation of Ni/Cu/ZnO (NCZ) nanocomposites (NCs) with polyaniline (PANI) plastic by in situ method results in unique properties. A modified sol‐gel method was used for synthesizing mixed metal NCs. The PANI was synthesized by the chemical‐oxidative method. TEM, FTIR, FESEM, UV‐visible, and XRD techniques were used for characterizing NCZ NCs, PANI, and NCZ/PANI NCs. The theoretical (computational) study was carried out to support the experimental results. The adsorption, magnetic, photocatalytic, photoluminescence, electrical, antibacterial, and anticorrosive properties of NCs were explored. The NCZ/PANI NCs were proved paramagnetic. The optical band gap of NCs observed from UV‐visible and computational techniques were comparable i. e., ∼2.32 eV. The NCs show 86.5 % corrosion inhibition efficiency for mild steel in acidic medium. The adsorption power of the Silica gel/NCs column was greater than the pure silica gel column. The NCs degrade methyl‐red dye in UV light. The antibacterial activity was investigated against E. coli (‐) and bacillus (+). No significant antibacterial activity was observed. The synthesized NCZ/PANI NCs were proved to be very good nanomaterials for adsorption, separation, magnetic, photocatalytic, electrical, and corrosion inhibitor.

“…PANI/TiO 2 composites : Due to a wideband gap, TiO 2 primarily absorbs UV-light, which accounts for only about 3–5% of sunlight, and limits its photocatalytic ability in the visible region [ 45 , 46 ]. However, PANI exhibits high absorption coefficients in the visible light range, charge carriers with a high mobility, non-toxicity, and low-cost synthesis, and in addition is an excellent electron donor [ 47 ]. As a result, PANI is often used to delay the recombination of electron–hole pairs, enhance the charge separation efficiency, and improve the photocatalysis efficiency of TiO 2 [ 21 , 22 ].…”

Photocatalysts provide a sustainable method of treating organic pollutants in wastewater and converting greenhouse gases. Many studies have been published on this topic in recent years, which signifies the great interest and attention that this topic inspires in the community, as well as in scientists. Composite photocatalysts based on conducting polymers and metal oxides have emerged as novel and promising photoactive materials. It has been demonstrated that conducting polymers can substantially improve the photocatalytic efficiency of metal oxides owing to their superior photocatalytic activities, high conductivities, and unique electrochemical and optical properties. Consequently, conducting polymer/metal oxide composites exhibit a high photoresponse and possess a higher surface area allowing for visible light absorption, low recombination of charge carriers, and high photocatalytic performance. Herein, we provide an overview of recent advances in the development of conducting polymer/metal oxide composite photocatalysts for organic pollutant degradation and CO2 conversion through photocatalytic processes.
