A super-hydrophobic organic nano coating was prepared by adding a new type of nano-SiO2 particles to a solvent-based varnish with mechanical blending methods. Isopropyl alcohol, glycerol triacetate and silicone oil were added into the system to improve hydrophobic property. The result showed that the water droplet contact angle on the coating surface reaches 165° by adjusting the ratio of each component, which leads to its super-hydrophobic property.
