Abstract
Compositions and processes are disclosed for forming hydrophobic coatings and lubricant-infused surface coatings. Coatings may be applied to various substrates without prior chemical or temperature treatment of the substrates and over large and irregular surfaces. Coatings are self-healing, antifouling, and have enhanced lifetimes.
Claims20
A structure having a slippery surface, the structure comprising:
- an abrasion resistant composite structure comprising a porous reinforcing material and a repellent interfacial material;
- and
- a lubricant-infused surface coating on an exposed surface of the composite structure.
A reinforced structure having a slippery surface, the reinforced structure comprising
- a substrate,
- a reinforcing material,
- a repellent material, and
- a lubricant,
- wherein an exposed surface of the reinforced structure comprises a lubricant-infused surface coating, and
- wherein the reinforcing material and the repellent material together form an abrasion resistant interface between the substrate and the lubricant-infused surface coating.
3 more elements
A process for making a slippery durable structure, comprising
- combining a repellent material with a reinforcing material to form an abrasion resistant composite structure,
- delivering a lubricant to the composite structure, and
- forming a lubricant-infused surface coating on an exposed surface of the composite structure to provide a slippery surface.
