报告摘要：

Surface wetting has been extensively studied in recent decades for a wide range of applications. For example, water-repellent superhydrophobic coatings can be applied for easy-cleaning, anti-corrosion, and anti-icing applications. On the other extreme, superhydrophilic surface can prevent fogging on optical lenses and screens. While we have learnt a lot from Nature on fundamental sciences behind these special wettability surfaces, the engineering applications often pose further constraints. In this talk, I will begin with some fundamentals on solid surface wetting states. Specific examples will be given to illustrate how these fundamental principles are applied in formulating various applications. Main challenges towards practical applications will be raised and discussed. Development of these special wettability surfaces must take into consideration the application environment. Practically useful coatings have to meet manifold requirements including low cost, easy processibility, scalability (large quantity for large area), applicability to complex shapes, flexibility to incorporate different functional requirements, and mechanical robustness and reliability within the designed life span.
