N2 - Super hydro/oleophobic cotton fabrics were prepared using nanoparticle vapor deposition and molecu-lar vapor deposition techniques. The surface was roughened by trimethylaluminum/water nanoparticlesfollowed by functionalization with (tridecafluoro-1,1,2,2-tetrahydrooctyl)trichlorosilane. This processimparted unique hydro/oleophobic properties (contact angle >160°). In contrast to wet chemistry pro-cesses, the chemicals used and the thickness of the coatings produced by this method could be controlledprecisely, which allowed for the minimization of waste generation while preserving the original prop-erties of the fabric. Dynamic contact angles were measured and the fabrics that were coated using thistechnique showed low-contact-angle hysteresis properties. Scanning electron microscopy and univer-sal attenuated total reflectance Fourier transform infrared spectroscopy confirmed the formation ofa nanostructure-roughened surface. Drop dynamics such as the force of droplet movement, work ofadhesion, and surface free energy were also calculated.
