Abstract:

 This study aimed to create thermally curable, water-borne polyurethanezinc oxide WPUZnO composite coating pastes with varying ZnO concentrations. ZnO nanoparticles were synthesized using a wet chemical process, and the resulting WPUZnO coating pastes were applied to PLA nonwoven fabrics NWFs. In characterization studies, differential scanning calorimetry DSC, scanning electron microscopy SEM, Fourier transform-infrared FTIR spectroscopy, and X-ray diffraction XRD analyses were conducted. Ultraviolet UV protection and antibacterial activity of fabrics were investigated. With WPUZnO composite coatings, the UV protection properties of the coated fabrics were enhanced compared to the uncoated fabric. The highest UPF value of 53.57 was obtained with the fabric coated with the formulation containing a ZnO concentration of 10. This fabric also demonstrated more effective antibacterial activity against both S. aureus and E. coli bacteria. Inhibition zone diameters against E. coli and S. aureus bacteria were measured as 15.5  0.70 mm and 18.25  0.35 mm, respectively. The results of this study illustrate that functional composite coatings for bio-based NWF structures hold great promise for producing effective UV protective and antibacterial materials, potentially setting the stage for future applications.
