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 comprising a three-dimensional mesh and a repellent interfacial material embedded within the porous reinforcing material;
- a lubricant-infused surface coating on an exposed surface of the composite structure;
- and
- wherein a height of the repellent interfacial material is equal to or greater than a height of the porous reinforcing material.
1 more element
A reinforced structure having a slippery surface, the reinforced structure comprising
- a substrate,
- a reinforcing material comprising a fibrous mesh,
- a repellent material embedded within the reinforcing material and comprising a pore-forming additive that is not removed from the 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 porous reinforcing material comprising a three-dimensional mesh by embedding the repellent material within the porous reinforcing material to form an abrasion resistant composite structure wherein a height of the repellent material is equal to or greater than a height of three-dimensional mesh,
- 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.
