| Résumé : |
Omniphobic surfaces offer the potential to repel both high and low surface tension liquids, including water, oils and alcohols. This property has attracted huge interest in recent years due to its broad impact on industrial applications, including self-cleaning, corrosion resistance, anti-fouling, anti-icing, anti-graffiti, and water-oil separation. |
