Summary: Superhydrophobic coatings are becoming increasingly popular due to their low maintenance requirements, high durability, and wide range of potential applications. These coatings can provide resistance to fouling, icing, smear, and corrosion, as well as the ability to separate oil from water. Consequently, the development of superhydrophobic materials is a topic of significant interest among academics worldwide. In this paper, a spray-coating deposition technique is utilized to deposit silica nanoparticles on glass using a sol-gel as a base. The resulting coating significantly increased transmittance to 99% at 600 nm. Water contact angle (WCA) and scanning electron microscopy (SEM) analysis of the coated layer's grade index and induced porousness demonstrated superhydrophobic behavior with a water contact angle exceeding 158 degrees.

Summary: In this study, hydrophilic silica nanoparticles and hydrophobic silane were used to modify the surface of polyurethane (PU) paint to improve its fouling properties. The addition of silica nanoparticles followed by silane modification resulted in minimal changes in surface morphology and water contact angle. However, when perfluorooctyltriethoxy silane was used to modify the PU coating blended with silica, the fouled area significantly increased compared to the unmodified PU coating. On the other hand, blending silica nanoparticles without silane modification reduced the fouled area. Additionally, coating the PU coatings with silica nanoparticles dispersed in different solvents using the dual-layer coating method improved the surface roughness and hydrophilicity. The use of paint thinner as a solvent resulted in a superhydrophobic and antifouling surface.
