Durable slippery colloidal coatings are created through the infiltration of particulate films with bilayer lubricant. The colloidal dispersion was prepared with low surface energy materials, and sprayed on the substrate forming a particulate thin film. Then, the viscous surfactant was thermally driven to the bottom and serve as adhesive primer. After lubricant infusion as the top protective layer, the slippery coatings are obtained and exhibit excellent surface-protective performance, including anticorrosion, antifouling, self-healing, anti-icing, and self-cleaning properties.
