Title:
STRUCTURED SURFACES THAT SHOW A LOTUS EFFECT
Document Type and Number:
WIPO Patent Application WO/2003/013827
Kind Code:
A1
Abstract:
The invention relates to self-cleaning surfaces that are generated by a stochastic structure or by combining two periodic structures. Surfaces having non-wetting properties have a number of economically important features. The surfaces that are difficult to wet with water combined with a suitable structure are referred to as so-called lotus effect surfaces. Dirt is simply removed from these surfaces by moving water, thereby eliminating the need for a very cost- and time-consuming cleaning of the surfaces.
