“…1. The PANI characteristic peaks at 2Ө= 11.05°, 12.99°, 16.6°, and 19.15° could be attributed to the parallel structure periodically interlaced with the vertical in the polymer chains (Zeng et al, 2016). Peaks at 2Ө= 18.4°, 31.5°, 35.7°, 43.3°, 54.40°, 57.34°, and 63.03° corresponded to (h k l) values of 111, 220, 311, 400, 422, 511, and 440, indicating the presence of single-phase CuFe 2 O 4 with good crystallinity (JCPDS file No: 25-0283) (Science & Kumar, 2019).…”

M AGNETIC nanocomposites loaded with antimicrobial drugs have grown in popularity for treating infectious diseases due to their magnetic properties and the ability to penetrate bacteria cells. In this research, Cu x Fe 3-x O 4 nanoparticles and Cu x Fe 3-x O 4 /PANI nanocomposites were synthesized, characterized, and examined for their antimicrobial activity. The in-situ oxidative polymerization of aniline in the presence of Cu x Fe 3-x O 4 nanoparticles produced Cu x Fe 3-x O 4 /PANI nanocomposites with distinct spinel ferrites. XRD, FT-IR, VSM, SEM, EDX, TEM, and XPS techniques confirmed the successful synthesis of the Cu x Fe 3-x O 4 /PANI nanocomposites. The analysis of magnetization patterns of Cu x Fe 3-x O 4 /PANI nanocomposites revealed their superparamagnetic characteristics. With increasing Cu 2+ ratios, both the pure copper ferrites nanoparticles and the Cu x Fe 3-x O 4 /PANI nanocomposites exhibited enhanced antimicrobial effects against gram-positive (Staph), gram-negative (E. coli, P. aeruginosa, and K. pneumoniae), and fungi such as (C. albicans), which is consistent with decreasing the order of crystal size (nm) and the lattice strain, where crystal size and lattice strain decreased with increasing Cu 2+ ratio. SEM micrographs revealed changes in bacterial shape, deformation of fungal cell walls, and bacterial and yeast colonies collapsing. Furthermore, the nanocomposites are more effective against gram-negative bacteria and Candida albicans than gram-positive bacteria, displaying the alteration of bacterial shape, fungal cell wall deformation, and collapsing bacterial and yeast colonies. The results presented an approach for using Cu x Fe 3-x O 4 and Cu x Fe 3-x O 4 /PANI as an alternative promising antimicrobial agent against several multidrugresistant microbes.

“…In addition to good photocatalytic capabilities, it is also vital to fabricate the photocatalyst, which is recyclable. In order to synthesize magnetically recyclable photocatalysts, Zeng et al incorporated MnFe 2 O 4 with PANI via facile in-situ oxidative polymerization method [ 41 ]. The combination of PANI and MnFe 2 O 4 improves the photocatalytic activity by providing more surface area and smaller particle size, and thus effectively hinders the recombination of photoinduced charge carriers.…”

Conductive polymers have been widely investigated in various applications. Several conductive polymers, such as polyaniline (PANI), polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) (PEDOT)), and polythiophene (PTh) have been loaded with various semiconductor nanomaterials to prepare the composite photocatalysts. However, a critical review of conductive polymer-based composite photocatalysts has not been available yet. Therefore, in this review, we summarized the applications of conductive polymers in the preparation of composite photocatalysts for photocatalytic degradation of hazardous chemicals, antibacterial, and photocatalytic hydrogen production. Various materials were systematically surveyed to illustrate their preparation methods, morphologies, and photocatalytic performances. The synergic effect between conductive polymers and semiconductor nanomaterials were observed for a lot of composite photocatalysts. The band structures of the composite photocatalysts can be analyzed to explain the mechanism of their enhanced photocatalytic activity. The incorporation of conductive polymers can result in significantly improved visible-light driven photocatalytic activity by enhancing the separation of photoexcited charge carriers, extending the light absorption range, increasing the adsorption of reactants, inhibiting photo-corrosion, and reducing the formation of large aggregates. This review provides a systematic concept about how conductive polymers can improve the performance of composite photocatalysts.
