A remarkable ultrahydrophobic surface area
Creation of textured silicone surfaces with remarkable superhydrophobic properties
Researchers from the Carnot MICA Institute have just successfully developed textured silicone surfaces with remarkable ultrahydrophobic properties. These surfaces, characterised by extreme resistance to wetting by aqueous solutions, have also shown promising behaviour in terms of controlling bacterial growth, paving the way for the development of new biomaterials. Chosen by the research teams, the surface texturing technique by femtosecond laser has enabled the production, for specific machining conditions, of four types of surface texture, each with ultrahydrophobic properties. An unexpected consequence of this result: the need to develop a totally new method for characterising ultrahydrophobicity, based on tensiometric techniques.
