| 英文摘要 | Superhydrophobic nanocomposite coating was designed using nanodiamonds (NDs) and siloxane-acrylic resins via the spray coating process. The NDs coating showed a high-water contact angle of 154 degrees and a very low sliding angle of 6 degrees. After 10 cycles of icing and de-icing, the coating exhibited a delay in ice formation time and reduced ice adhesion strength (similar to 44.56 kPa) in comparison with the bare metal (similar to 77 kPa). The superhydrophobic nanocomposite coating offers excellent anti-bacterial adhesion properties; revealing a 73% decrease of Escherichia coli (E. coli) bacterial colony on the superhydrophobic NDs coated sample compared to the blank sample after 24 h of incubation. The electrochemical impedance spectroscope measurement reveals an impedance value of 106 Omega cm(2) at 4 h of immersion, signifying that the coating exhibited corrosion protection ability at the initial hours of immersion. This protective property is comparable good for a very thin coating of 10 mu m thickness. Besides, there was a minimal detachment of the coating from the substrate during the cross-cut adhesion test, and no sign of crack after the impact test indicating a good surface adhesion property. |
