Cotton fabric is a natural polymer material commonly used in hospital and food industries, for example, gowns, gloves, aprons, and face masks. In this work, trichloro(1H,1H,2H,2H-perfluorooctyl)silane and nanoscale fumed silica is used to manufacture fluorinated-silica nanoparticles (FSNs). The dip-coating method is used to provide anti-biofouling and bacterial cross-contamination protection on the cotton fabric surface. The presence of FSNs on the coated cotton fabric sample surface was confirmed by the Fourier transform infrared spectroscopy (e.g., –CF3 peak) and the images of scanning electron microscope (e.g., roughness). The water contact angle measurements show high water contact angle (i.e., >150º, superhydrophobic). The cotton fabric sample with biofouling-resistant surfaces show a significant reduction in biological contaminants (e.g., virus, bacteria, protein, blood, and fungi) adhesion, which can potentially improve personal hygiene. |
