Ice buildup (via super-cold humid air, frost formation, frozen condensation or freezing rain) poses significant operational and safety challenges on wind/marine turbines and aeroplanes. For wind energy generation, these turbines often suffer significant drops in efficiency/production, severe damages or accidents. Ice accumulated on aircraft during flight seriously deteriorates aerodynamic performance and may lead to disasters. The key aim of this project is to research hybrid smart thin materials combining piezoelectric films (such as doped-ZnO) and inherently icephobic surface/coatings, to generate surface acoustic waves (SAWs), which are used as anti-icing and de-icing mechanisms to mitigate real-time ice issues for the wind turbines. The innovative idea is to research hybrid piezoelectric thin films to generate SAWs directly onto surfaces of structures which can then excite a synergistic mechano-thermal effect for both anti-icing/de-icing functions, and to simultaneously perform ice sensing using these thin film acoustic wave devices. A key advantage of this developed smart thin film material platform with icephobic coatings is its seamless integration onto surfaces of turbine blades with energy efficient and wireless actuation/control/sensing functions. Some of the work will include the experimental investigation of droplet impact with low-temperature droplets and on low-temperature surfaces in order to simulate the effect of cold climates on both wind turbines and aircraft.The project has the following key research work: (1) Design/deposit/characterize advanced piezoelectric doped ZnO films on turbine blade materials (for example, aluminium plates) using magnetron sputtering deposition. (2) Design, fabricate and simulate thin film material SAWs and investigate their piezoelectric and acoustic wave properties, focusing on multilayer based vibration modes and thermal effects. (3) Smart icephobic surfaces and coatings (including SAW compatible superhydrophobic/SLIPS/SOCAL/CYTop/elastic coatings). (4) Thin film piezoelectric materials for integrated ice sensing and monitoring. (5) Anti-icing/de-icing performance using thin film acoustic waves with smart icephobic coating materials.

冰的积聚（通过超冷的潮湿空气，霜冻形成，冷冻或冷冻雨）对风/海洋涡轮机和飞机构成了巨大的操作和安全挑战。对于风能产生，这些涡轮机通常在效率/产量，严重损坏或事故方面遭受显着下降。飞行期间在飞机上积聚的冰严重恶化了空气动力学性能，并可能导致灾难。该项目的主要目的是研究结合压电膜（例如掺杂的Zno）和固有的冰层表面/涂料的混合智能材料，以产生表面声波（SAWS），这些波浪（SAWS）用作防冰和去染色机制，以减轻风力涡轮机的实时冰问题。创新的思想是研究混合压电薄膜，以直接在结构的表面上产生锯，然后可以激发抗染色/去冰功能的协同机械热效应，并使用这些薄膜声波手段同时执行冰。这种发达的智能薄膜材料平台带有冰淇淋涂料的一个关键优势是它的无缝集成在具有节能和无线驱动/控制/传感功能的涡轮叶片表面上。 Some of the work will include the experimental investigation of droplet impact with low-temperature droplets and on low-temperature surfaces in order to simulate the effect of cold climates on both wind turbines and aircraft.The project has the following key research work: (1) Design/deposit/characterize advanced piezoelectric doped ZnO films on turbine blade materials (for example, aluminium plates) using magnetron sputtering deposition. （2）设计，制造和模拟薄膜材料锯并研究其压电和声波特性，重点是基于多层的振动模式和热效应。 （3）智能冰表面和涂料（包括兼容兼容的超疏水/slips/socal/cytop/弹性涂料）。 （4）用于集成冰和监测的薄膜压电材料。 （5）使用薄膜声波和智能冰层涂料材料使用薄膜声波的抗冰/去冰性能。
