Webinar on superhydrophic surfaces - Sign up here!

Your are invited to the Attension Webinar "Superhydrophobic surfaces: robustness & biomimetic applications" held by Dr Robin Ras. You can choose to attend on Wednesday 30th from 5pm (CET*) or Thursday 31st of May 2012 from 9am (CET*).

 

This webinar was held a first time in the summer 2011 and people who could not attend back then due to the limited number of places, will have a second chance. The presentation will be very similar but will also include a few updates.

 

Speaker:

Dr Robin Ras, Aalto University, Finland

 

Topics covered:

• Superhydrophobicity basics
• Examples of biological superhydrophobicity
• Durability issue of superhydrophobic surfaces
• Solutions to improve durability of superhydrophobic surfaces

I want to register to the Thursday 31st of May session, starting from 9am CET

 


ABSTRACT

 

Surfaces that are superhydrophobic, i.e. non-wetting to water, have contact angles approaching 180°, and attract interest because water droplets easily roll off leading to self-cleaning properties. The best known example from nature is the Lotus leaf that stays perfectly clean even in muddy waters. Superhydrophobicity is often used by plants or animals, for properties quite different from self-cleaning, such as anti-fogging and even breathing underwater.


"In this presentation I will discuss the basics of superhydrophobicity, and give examples of biological superhydrophobicity, and their potential use for bio-inspired technologies. Furthermore, I also discuss the problem of durability of superhydrophobic surfaces. Development of durable non-wetting surfaces is hindered by the fragility of the microscopic roughness features that are necessary for superhydrophobicity. Mechanical wear on superhydrophobic surfaces usually shows as increased sticking of water, leading to loss of non-wettability. Some examples are given about how superhydrophobic surfaces can be made more robust.Dr. Robin Ras

 


SPEAKER BIOGRAPHY

 

Dr. Robin H. A. Ras is Academy Research Fellow at the Department of Applied Physics at Aalto University (formerly Helsinki University of Technology, Finland).
