Fabrication of robust and durable slippery anti-icing coating on textured superhydrophobic aluminum surfaces with infused silicone oil
正文
Abstract(#br)A facile and durable biomimetic slippery anti-icing coating was prepared by infusing nontoxic and inexpensive lubricating silicone oil into superhydrophobic dual-scale micro/nano-structured (MNS) aluminum surfaces. Superhydrophobic surfaces were fabricated via the combination of simple chemical etching and anodization, followed by surface modification with poly(dimethylsiloxane) (PDMS). Compared to superhydrophobic coatings, silicone oil-infused polydimethylsiloxane (SOIP) coating displays a low ice-adhesion strength of 22 ± 5 kPa on the structured surface. Moreover, the SOIP coating sustained low ice-adhesion strength (35 ± 15 kPa) even when the temperature was lowered to −25 °C. The MNS-surface exhibits excellent durability, showing a low ice-adhesion (108 kPa) after 20 icing/de-icing cycles and long-term icephobicity (55 ± 13 kPa) after four months' exposure in ambient environment. We also examined the influence of surface morphology on ice-adhesion strength, the SOIP modified MNS-surface displays better anti-icing properties compared to a nano-structured (NS) surface under harsh conditions; icing/deicing and abrasion cycles. The MNS-surface act as reservoir to hold the excess amount of oil, thus reducing the loss of lubricant during icing/deicing cycles. The proposed technique is very simple and cost-effective, and most importantly it can be applied for production of durable and scalable anti-icing coatings for various practical applications.

信息更新：

美国总工厂生产的0.5KG原始包装的PDMS延期至2021年9月16日后才能交货，默认我们将发国内库存的进口分装产品（02085925-0.5KG）；另受制于有机硅大幅涨价潮影响，2021年9月1日后将上调销售价格，另行通知。Dow Corning=道康宁=Dow SiL=陶氏，都是同一家公司。 2021.09.01更新

美国总工厂生产的0.5KG包装的PDMS恢复正常进口，合法正规，质量金标准，欢迎订购使用。并承诺从我司购买的皆为原厂包装,100%未开封,附带技术手册,非国产灌装仿制、非分装、非仿冒外包装产品,可以放心使用。大量订购更有优惠。2021.04.01更新

备注：由于dowsil与道康宁公司合并，美国总工厂生产的PDMS，价格涨幅高达1倍之多，因针对科研用户使用，特备货规格0.5KG。如果您需要美国总工厂原厂生产的大规格包装的预定，可以与QQ 11366508联系给予报价/货期。2021.05更新
