| 英文摘要 | The corrosion protection and ice -over delay of aluminum alloys have always been pressing issues. Lotus -inspired superhydrophobic materials show great potential in the field of corrosion prevention and delayed icing, but they are currently prone to failure due to wetting and adhesion by low surface tension liquids. In this paper, we constructed a superamphiphobic (superhydrophobic and superoleophobic) organosilane-grafted attapulgite (OGATP) coating on 5083 aluminum alloy substrates using ATP, tetraethyl orthosilicate (TEOS), and 1 H,1 H,2 H,2 H-perfluorooctyltriethoxysilane (PFAS) through hydrolysis -condensation reaction and spraycoating technique. The coating exhibits contact angles greater than 150 degrees and sliding angles less than 10 degrees for water, glycerol, ethylene glycol, peanut oil, and even n-hexadecane with surface tension@20 degrees C of 27.5 mN/m. Through studying surface morphologies, chemical compositions, electrochemical behaviors, self-cleaning, and anti -icing performance, it was found that the R ct and |Z| 0.01 Hz of the protected aluminum alloy increased by four orders of magnitude with a corrosion inhibition efficiency of 99.99 %, demonstrating excellent anti -corrosion functionality. Additionally, icing test results at -5 degrees C, -10 degrees C, and -15 degrees C show that the prepared coating exhibits significant delayed icing performance. We believe that the integration of properties such as water -oil repellency, self-cleaning, anti -corrosion, and anti -icing will enable superamphiphobic materials to demonstrate enormous application prospects in various fields. |
