Abstract

Water-repellent coatings have a number of engineering applications, including easy-cleaning, anti-corrosion, and anti-icing. In this talk, I will begin with the materials science fundamentals on water repellence, and then explain how these fundamental principles are applied to the development of water-repellent and icephobic coatings. Specific examples will be given for coatings on composites and aluminum alloys, two important classes of industrial materials. Practically useful coatings have to meet manifold requirements including mechanical durability, low cost (non-reliance on expensive equipment and can be easily processed), scalability (large quantity for large area), and applicability to complex shapes, etc. These requirements can be taken into consideration at the coating formulation stage. Future outlooks on water-repellent coatings will be shared. Prof. Chen will also take the chance to share a reflection on his personal research journey so far, using the well quoted “connecting dots” by Steve Jobs.
