The Study Of Anti-icing Performance Of Ultra Smooth Surface Infuse With Fluorinated Lubricant

Anti-icing is of great significance. Currently used active chemical, thermal, and mechanical techniques of ice removal are time-consuming and costly. Recent efforts for developing ice-phobic surfaces have been mostly devoted to utilizing anti-icing coating technology, especially super-hydrophobic coating, yet these surfaces fail in the extreme conditions, such as under the effect of shear stress. To address these problems mentioned above, the concept of slippery liquid-infused porous surface(SLIPS) was proposed.At first, we drop the stable, ultra smooth perfluorinated polyether lubricant into the nano-SiO2 / fluorine silicon sol/epoxy resin coating with high hydrophobicity and micro rough structure. Found due to the introduction of lubricant, the rolling angle of water gets smaller. What’s more, we demonstrate that SLIPS-coated surfaces not only suppress ice accretion by effectively removing sub-cooled water but also exhibit at least an order of magnitude lower ice adhesion than hydrophobic materials.But the anti-icing of the lubricating oil/nano-SiO2/ epoxy coating reduces after several simulation test of freezing rain. So we create a porous substrate containing short glass fiber/fluorine silicon sol/epoxy, then infuse with perfluorinated polyether lubricate. Found the performance of anti-icing better than the SiO2 coating infused with lubricating oil. At the same time, the durability of anti-icing had a great enhancement.
