This study investigated the development of antibacterial fabrics coated with oil palm boiler ash (OPBA) and zinc oxide (ZnO). OPBA was processed via ball milling and co-precipitation to control the nanoparticle size and optimize silica content. The resulting OPBA was combined with ZnO to form a hybrid nanocomposite. The cotton fabric was coated with this nanocomposite using the dip-pad-dry-cure method. The morphology, thermal properties, crystal structure, and antibacterial activities were evaluated. Scanning electron microscopyenergy-dispersive X-ray spectroscopy confirmed the presence of the nanocomposite and its constituent elements on the fabric surface. Differential scanning calorimetry showed an increase in the melting temperature (Tm) of the coated fabrics, although this later decreased with increasing ZnO concentration. X-ray diffraction analysis revealed a reduction in the intensity of the characteristic cellulose peaks, indicating a change in the cellulose structure upon coating with OPBA and ZnO. Antibacterial tests showed that the nanocomposite coating inhibited the growth of Staphylococcus aureus bacteria on OPBA:ZnO-coated fabrics at ratios (1:1), (1:2), and (0:1), showing inhibition zones of 3.9, 0.6, and 0.9mm, respectively. Meanwhile, Escherichia coli-coated fabrics with OPBA:ZnO at ratios (1:1), (1:2), and (0:1) showed inhibition zones of 0, 1.1, and 2mm, respectively. Furthermore, untreated cotton fabrics showed an inhibition zone of 0. These results demonstrate the potential of this hybrid nanocomposite coating for producing antibacterial textiles suitable for healthcare applications. © 2025 the author(s), published by De Gruyter.
