Abstract: In this paper, a MOF-based anti-icing coating was prepared by in situ synthesis of the silicone oil lubricating layer on the UiO-66-NH2 coating via click reaction. The amount of silicone oil on surface wastuned by reaction time. The anti-icing performance of the oil-grafted MOF coatings (OGMCs) with different amounts of silicone oil was investigated. The surface morphology and composition were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and contact goniometer. The results show that silicone oil is successfully synthesized and covalently bond to MOF. The OGMCs keep the original micro-nanostructures of MOF coating, as well as the crystal structure of UiO-66. The amount of silicone oil on OGMC increases with reaction time, however, the ice nucleation temperature and ice adhesion decreases first and then increases when the reaction time increases. The anti-icing performance of MOF coating is closely related with the amount of silicone oil. The anti-icing performance of OGMC is optimized when the reaction time is 12~18 h and the molar ratio of Si to Zr is 8~12. The ice nucleation temperature reaches -29.6 ℃ and the ice adhesion reaches 8.8 kPa.
