Amphipathic proteinaceous coating on nanoporous polymer
View Patent ↗The present invention relates to the formation of amphipathic proteinaceous coatings on nanoporous polymers.
1. Composite structure comprising nanoporous amorphous fluoropolymer having a proteinaceous amphipathic coating thereon, said coating being applied without heat, wherein the pores of said polymer have an average diameter of no greater than about 5 nanometers and wherein said nanoporous polymer is hydrophobic, characterized by a wetting angle of at least about 90°.
2. The composite structure of claim 1 wherein said proteinaceous amphipathic coating increases the water wettability of said polymer, said increased water wettability being characterized by a reduction in wetting angle of at about least about 15°.
3. The composite structure of claim 1 having the oxygen permeability of at least about 80% of the oxygen permeability of said nanoporous polymer.
4. The composite structure of claim 1 wherein said nanoporous polymer is a film.
5. The composite structure of claim 4 wherein said film is a contact lens.
6. The composite structure of claim 1 wherein said proteinaceous amphipathic coating is hydrophobin.
