Frost free surfaces and method for manufacturing the same

摘要

Frost-free surfaces and methods for manufacturing such surfaces are described. The frost-free surfaces reduce ice build-up, prevent vapor condensation and reduce adhesion force between ice and a solid substrate. The surfaces can be on parts used in devices where superhydrophobic properties may be obtained post or during device manufacturing. The superhydrophobic properties are the result of aluminum oxide clusters made on such surfaces.

主权项

1. A frost-free device comprising parts whereby the parts are superhydrophobic and comprise nanoclusters of aluminum oxide, whereby the nanoclusters are between 800 nm to 15 microns in width, 700 nm to 10 microns in height and 300 nm to 40 microns apart, wherein the nanoclusters are pyramid-line in shape.
