This research proposal describes an initial partnership between the University of Victoria and RT Primetechnologies for the development of water repellent (super hydrophobic) films. A general problem withdifferent types of surfaces in different areas, including textiles, medical, automotives and military, is related totheir wettability. Ideally, there are cases where it would be highly desirable to tailor the surface properties suchthat it can not accumulate water. For instance, a car window that does not accumulate water would providemuch better visibility under rain and fog. A super hydrophobic vest can improve buoyancy or keep a soldier dryunder adverse weather situations. There are several approaches to coat surfaces that impart hydrophobicity.However, a general technology that can be directly applied in different types of surfaces is not available. Herewe suggest to use nanoparticles to develop a super hydrophobic liquid that can be applied on several differentsituations. The goal, within the time frame of the ENGAGE program, will be mostly to test different syntheticroutes for nanoparticle fabrication and functionalization. Successful systems will be directly transferred to RTPrime that will evaluate their commercialization potential and further develop the technology.

这项研究建议描述了维多利亚大学和RT Primetics为开发防水(超疏水)薄膜而建立的初步合作伙伴关系。在不同的领域，包括纺织品、医疗、汽车和军事在内的不同类型的表面，一个普遍的问题与它们的润湿性有关。理想情况下，在某些情况下，非常需要对表面属性进行调整，例如不能积水。例如，一扇不积水的车窗可以在雨雾中提供更好的能见度。超级疏水背心可以提高浮力，或使士兵在恶劣天气情况下保持干燥。有几种方法可以涂覆具有疏水性的表面，但没有一种通用的技术可以直接应用于不同类型的表面。在这里，我们建议使用纳米颗粒来开发一种超疏水液体，这种液体可以应用于多种不同的场合。在Engage计划的时间框架内，目标将主要是测试纳米颗粒制造和功能化的不同合成路线。成功的系统将直接转移到RTPrime，由RTPrime评估其商业化潜力并进一步开发技术。
