This research has been conducted with the objective of multi-functional finishing on cotton fabric for improving different properties such as photocatalytic activity, electrical conductivity, UV blocking, and antibacterial. To this end, in situ synthesis of graphene/zinc stannate nanocomposite was carried out and its effect on the cotton properties was investigated. The structure and morphology of the fabric surface has been examined by field emission scanning electron microscopy (FE-SEM) and its chemical structure has been elucidated by X-ray photoelectron spectroscopy (XPS). The electrical conductivity of coated fabrics was improved significantly due to the presence of graphene on the surface of cotton fabrics. The photocatalytic activity of the treated fabrics with graphene/zinc stannate nanocomposite was tested by degradation of methylene blue in aqueous solution under sunlight irradiation, which demonstrated excellent photocatalytic efficiency of the nanocomposite. The antibacterial activities of the samples against two common pathogenic bacteria including Escherichia coli and Staphylococcus aureus have been also assessed, which suggested that the graphene/zinc stannate nanocomposite can function effectively as antibacterial agents. Moreover, the nanocomposite finished cotton fabric showed proper UV blocking activity.
