SIPW05 - SIP Follow on: Mathematics of sea ice in the twenty-first century

In the last decade the search for passive anti-icing surfaces which are able to delay ice formation and/or minimise ice adhesion has intensified. Precision nanoengineering of liquid repellent surfaces offers some interesting possibilities. As a related problem, the issue of (supercooled) liquid impact resistance and general robustness of surfaces has also been considered widely. In this presentation, I will first summarise our work (and also reference notable reports from other groups) in the past decade on precision nanoengineering of surfaces. I will highlight some of work on how to engineer surfaces with precision while striking a trade off with robustness and scalability of manufacturing process which most practical applications demand. Next, I will also aim to show how surface properties may be inadequate and how bulk mechanical materials properties of the coatings/substrate may offer further insights into improving overall performance. I will finish with highlighting some example of open questions/opportunities.
