Scientific breakthroughs into surfaces/interfaces with high overall durability are critical to meet humanity's aspirations for sustainable development. With this context, I seek to undertake fundamental research to nanoengineer new bioinspired liquid-repellent films featuring resistance to sustained high-speed impact, fatigue and continuous flow (shear). My specific objectives are to:1) nanoengineer robust and flexible films with amphiphobicity (i.e. repellence to water and low surface tension liquid) built through thickness2) nanoengineer multi-layered amphiphobic film with mechanical anisotropy and energy dissipative mechanisms for impact/fatigue tolerance3) develop new insights into visco-elasto-plastic failure of the amphiphobic films using electron microscopy integrated nanomechanical tests and exploit them to engineer robust piezocatalytic films 4) perform first high-speed (~350 m/s) liquid/solid particle impact experiments on robust amphiphobic films, demonstrate their anti-icing, anti-scaling and optical transparency potential and to exploit robust piezocatalytic films to introduce continuous flow water remediation for pollution and disease control.The proposed protective nanoengineered films offer a substrate-independent solution for impact/erosion issues that plague transport systems, wind-turbines and offshore installations, and infrastructure exposed to harsh weather. These applications will also benefit from passive anti-icing/scaling potential of our films. With optical transparency, the films may prevent contamination of windows/windshields and handheld devices (e.g. phones/tablets). Furthermore, the piezocatalytic films may be retrofit to industrial/domestic pipes to enable continuous water remediation - this will reduce water waste and the antimicrobial resistance (AMR) burden, and potentially save millions of lives/year. Overall, the fellowship will contribute to sustainable development and meeting the European Green Deal targets.

在具有高整体耐久性的表面/界面方面的科学突破对于满足人类对可持续发展的期望至关重要。在这种情况下，我寻求进行基础研究，以纳米工程新的生物启发的液体排斥膜具有耐持续高速冲击，疲劳和连续流动（剪切）。我的具体目标是：1）具有两亲性的纳米工程坚固和柔性薄膜通过厚度构建的（即，对水和低表面张力液体的排斥性）2）具有机械各向异性和用于冲击/疲劳耐受性的能量耗散机制的纳米工程多层双疏膜3）使用电子显微镜集成纳米机械测试开发对双疏膜的粘弹塑性失效的新见解，并利用它们来设计坚固的压电催化膜4）进行第一次高速（~350 m/s）液体/固体颗粒对坚固的两疏膜的冲击实验，证明了它们的防冰性，抗结垢和光学透明的潜力，并利用强大的压电催化膜引入连续流动的水修复污染和疾病控制。拟议的保护性纳米工程薄膜提供了一个基板独立的解决方案，为影响/侵蚀问题困扰着运输系统、风力涡轮机和海上设施以及暴露在恶劣天气下的基础设施。这些应用也将受益于我们薄膜的被动防冰/防结垢潜力。由于具有光学透明性，该膜可以防止窗户/挡风玻璃和手持设备（例如电话/平板电脑）的污染。此外，压电催化膜可以改装到工业/家用管道中，以实现连续的水治理-这将减少水浪费和抗菌素耐药性（AMR）负担，并可能每年挽救数百万人的生命。总体而言，该研究金将有助于可持续发展和实现欧洲绿色交易目标。
