Abstract
Because of the problems caused by icing and snow, it is meaningful to develop coatings for anti-icing. In this paper, a superhydrophobic coating was successfully prepared by compounding fluorine-containing acrylate polymer, polysiloxane and nano-SiO2. Results of Fourier transform infrared spectroscopy (FT-IR) showed that epoxy groups in fluorine-containing acrylate polymer were partially cross-linked with silanol groups in polysiloxane, while self-crosslinking of silanols dominates the curing reaction. It was proven that there was a positive correlation between water contact angle (WCA) and nano-SiO2 amount, exhibiting a maximum WCA value of 153.6°. Nevertheless, the superhydrophobic coating is subject to collapse and the nano-particles could be scrubbed away during icing. As a result, the superhydrophobicity had trivial contribution to deicing in this experiment.
