Aim: To develop sustainable and efficient methods based on nanotechnology to reduce problems and costs with ice build-up.

Ice causes major problems on airplanes, wind turbines and in heat exchangers. Today’s methods using heating and chemical treatments are expensive, can be inefficient and non sustainable. Nanotechnology can create surfaces where the ice does not stick. The aim is to develop sustainable and efficient methods based on nanotechnology to reduce problems and costs with ice build-up.

 

Nanostructured surfaces against ice have never been tested in such a large scale before. It will be a big challenge to make the surfaces dirt repellent and wear resistant in severe environment. The nanotechnology also opens up for new solutions within other industrial sectors/applications where ice buildup creates problems.

 

Result summary

 

The aim of the project has been to develop coatings for passive anti-ice protection in the wind, aircraft and heat exchanger industries. The strategy for achieving this goal has been to optimize the surface chemistry and the surface topography on the nanometer scale. 

 

The lead ideas to reduce ice formation have been to use superhydrophobic, i.e. strongly water repellent surfaces, and surfaces that expose functional groups that are classified as structure breakers. 

 

An important aspect of the work has been to understand on a fundamental level why or why not these concepts work. At the start of the project, a thorough literature review was performed to identify the state-of-the-art.
