Electrochemical performance of low-cost PANI-anchored CuS electrode for lithium-ion batteries

Photoresponsive CuS@polyaniline nanocomposites: An excellent synthetic bactericide against several multidrug-resistant pathogenic strains

“…The phenomenon of peak intensity reduction has been consistently observed in various nanomaterials upon their interaction with PANI. 34,58–60…”

“…A PANI-modified CuS system was developed by Wang et al , demonstrating an enhanced photocatalytic performance which was attributed to the effective separation of the photogenerated charge carriers. 34 These findings suggest that the amalgamation of PANI with CuS or other inorganic nanomaterials may result in a synergistic or additive effect, which effectively enhances its antimicrobial performance. However, there is extensive research on the antimicrobial properties of these kinds of composite materials, while limited information is currently available regarding their effectiveness against clinically isolated bacteria.…”

“…56 Additionally, weak diffraction peaks appeared at 2θ values of 27.6°and 59.4°, which can be attributed to the (111) and (116) crystallographic planes of the hexagonal phase of CuS. 34,57 The absence of any additional phase peaks or diffraction peaks associated with impurities confirms the purity of CuS. On the other hand, the XRD pattern of the CuS@PANI NCs exhibits several small diffraction peaks at 2 θ = 9.2°, 15.2°, 17.9°, 20.3°, and 23.9°, as well as large peaks at 2 θ = 27.7°, 28.8°, 33.1°, and 47.8°.…”

However, a noticeable reduction in the peak intensities compared to those of the pristine CuS NPs is observed.…”

“…[30][31][32][33] This heightened attention is attributed to the use of copper (Cu) and sulfur (S) in CuS, as they are notably less toxic, comparatively abundant, and costeffective in contrast to Ag and many other materials typically employed in electronic and energy storage applications, such as tellurium (Te), cadmium (Cd), indium (In), lead (Pb), and molybdenum (Mo). 34 The optical absorption characteristics of CuS are comparable to those of widely utilized Ag or gold (Au) metals, which have extensive applications in the biomedical field. An advantageous aspect of the CuS compared to other near-infrared (NIR) materials such as Ag or silver sulfide (Ag 2 S) is its specific NIR range spanning from 700 nm to 1000 nm.…”
