Abstract
This disclosure relates to methods of making omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Uses thereof, including as flexible tubular structures that repel contaminants are also disclosed herein.
Claims30
A method of fabricating a material having a surface with hierarchical structures, the method comprising:
- a) depositing a moldable polymer onto a mold comprising microscale wrinkles and nanoscale features,
- b) curing the moldable polymer on the mold to provide a cured polymer, and
- c) removing the cured polymer from the mold to expose at least a surface of the cured polymer with hierarchical structures.
The method of any-ene-of-claims 24e-5, wherein the lubricant-tethering molecule layer is a fluorosilane layer and is formed using one or more compounds of the Formula I:
- wherein X is a single bond or is C1-6alkylene;
- n is an integer of 0 to 12;
- and R1, R2 and R3 are each independently a hydrolysable group.
