A new family of polymeric, lubricant-infused, nanostructured wrinkled surfaces was designed that effectively retains inert nontoxic silicone oil, after draining by spin-coating and vigorous shear for 2 weeks. The wrinkled surfaces were fabricated using three different polymers (Teflon AF, polystyrene, and poly(4-vinylpyridine)) and two shrinkable substrates (Polyshrink and shrinkwrap), and Teflon on Polyshrink was found to be the most effective system. The volume of trapped lubricant was quantified by adding Nile red to the silicone oil before infusion and then extracting the oil and Nile red from the surfaces in heptane and measuring by fluorimetry. Higher volumes of lubricant induced lower roll-off angles for water droplets, and in turn induced better antifouling performance. The infused surfaces displayed stability in seawater and inhibited growth of Pseudoalteromonas spp. bacteria up to 99%, with as little as 0.9 μL cm–2 of the silicone oil infused. Field tests in the waters of Sydney Harbor over 7 weeks showed that silicone oil infusion inhibited the attachment of algae, but the algal attachment increased as the silicone oil was slowly depleted over time. The infused wrinkled surfaces have high transparency and are moldable, making them suited to protect the windows of underwater sensors and cameras.

注入润滑剂的纳米皱纹聚合物表面的海洋防污行为
设计了一个新的聚合体，注入了润滑剂，纳米结构的皱纹表面，可有效保留惰性无毒硅油，然后通过旋涂和剧烈剪切排水2周。使用三种不同的聚合物（Teflon AF，聚苯乙烯和聚（4-乙烯基吡啶））和两个可收缩的基材（Polyshrink和shrinkwrap）制造起皱的表面，发现在Polyshrink上使用Teflon是最有效的系统。通过在输注前向硅油中添加尼罗红，然后从庚烷表面上提取油和尼罗红，并通过荧光法测量，来定量捕获的润滑剂的体积。较高的润滑剂量会导致较小的水滴降落角，进而导致更好的防污性能。假单胞菌属。细菌高达99％，注入的硅油低至0.9μLcm –2。在悉尼港水域进行的7周现场测试表明，硅油的注入抑制了藻类的附着，但是随着硅油的逐渐消耗，藻类的附着量增加了。注入的皱纹表面具有很高的透明度，并且是可模制的，因此非常适合保护水下传感器和摄像机的窗户。
