Super-hydrophobic surfaces: Preparation and testing

点击翻译按钮获取中文摘要

This proposal is a continuation of a research partnership between the University of Victoria (CAMTEC) and**RT Prime technologies. The main goal is the development of water repellent films (super hydrophobic films).**A general problem with different types of surfaces in different areas, including textiles, medical, automotives**and military, is related to their wettability. Ideally, there are cases where it would be highly desirable to tailor**the surface properties such that it can not accumulate water. For instance, a car window that does not**accumulate water would provide much better visibility under rain and fog. A super hydrophobic vest can**improve buoyancy or keep a soldier dry under adverse weather situations. There are several approaches to coat**surfaces and impart hydrophobicity. However, a general technology that can be directly applied in different**types of surfaces is not available. Our previous interaction with RT Prime (supported by a NSERC ENGAGE**grant) led to several synthetic routes for the fabrication and functionalization of super-hydrophobic**nanoparticles. We had explored several synthetic avenues systematically and narrowed down potential**candidates for a novel coating. This ENGAGE plus grant will allow us to further optimize our most promising**materials, improve on the methodology for film deposition and, finally, compare the properties of our new**technology with commercially equivalent products. A finalized and comprehensively evaluated product (with a**protocol for application and film deposition) will then be transferred to RT Prime, who will evaluate the**commercialization potential of our technology.
