Synergistic performance of biomedical textiles incorporated with cerium oxide carbon nanocomposites for the antibacterial and sunlight-driven photocatalytic activity of self-cleaning

This work inspects the antibacterial activity and sunlight-driven photocatalytic activity effect of nanocomposites of CeO2 and carbon as a surface coating onto the fabric with self-cleaning properties. The nanocomposites of CeO2 and carbon were confirmed by XRD, FTIR, Laser Raman and TEM, revealing the amorphous nature of carbon and the crystallographic structure of CeO2 nanoparticles. TEM depicted a sheet-like structure of carbon and orbicular morphology of CeO2. The nanocomposite was impregnated onto fabrics using an immersion and ultrasonication method. The fabrics impregnated with nanocomposites exposed a clear zone of inhibition of E. Coli and S.aureus bacterial strains, indicating potent bactericidal properties. The nanocomposite-impregnated fabrics show efficient and strong photocatalytic activity against P-Rosaniline Hydrochloride (PRH) dye, which was investigated at different concentrations of dye, repeatability, and reusability with time. The notable photocatalytic activity of the fabrics underscores their potential for use in anti-infection applications.
