摘要	In this article, a simple synthesis method was applied to form a branch and tendril structure using hydroxyl-terminated silicone sol modified silica nanoparticles at high temperature, followed by mixing with fluoro-containing polyacrylate emulsion (PFA) to obtained a polydimethylsiloxane (PDMS)-SiO2/PFA hybrid coating. The hydrophobic performance of the PDMS-SiO2/PFA coating was further enhanced through the synergistic action of Si-O and F group. The obtained coating has a similar surface structure of lotus leaf and the contact angle can reach 142.2 +/- 2.4 degrees. The PDMS-SiO2/PFA coating could delay the formation of frost crystal and the growth of frost layer. The defrosting droplets were difficult to adhere on the coating and could be easily rolled off for long frosting and defrosting cycles, which indicates the potential application of this coating in the field of frost suppression.
