Case 13139/12643

Water and Oil Resistant Fabrics with Tunable Surface Energy or Wettability

Keywords:

Tunable surface, Nanotexture, Wetting properties

Applications:

Oil-water separation, ground water cleaning, as well as various industrial coatings

Problem:

Need of surfaces with various extreme properties of wettability

Technology:

This invention presents the geometry required for creating super-oleophobic surface for the first time. The surface contains a protruding portion configured to protrude towards a liquid and a re-entrant portion opposite the protruding portion. It is essential that the re-entrant surface have negative curvature relative to the adjacent space. Further, the technology also include details on the creation of fabrics with tunable wettability, produced in a single step by electrospinning two components, a polymer and a fluorinated nanoparticles. In general, this process can be used to create superhydrophilic, superhydrophobic, super-oleophillic, and even super-oleophobic surfaces.

Advantages:
  • Super-oleophobic surface
  • Flexibility to produce surfaces having multiple desirable properties
