To best exploit these opportunities, new hydrophilic, hydrophobic, oleophobic, amphiphobic
and multifunctional coatings are being developed.
Fingerprints possess amphiphobic
properties [2-4], so an appropriate surface roughness and surface chemistry are both crucial factors in the fabrication of fingerprint-free surfaces.

Since fingerprints are mainly composed of water and skin oil (sebum), antifingerprint properties were achieved by developing amphiphobic
surfaces that repel water (hydrophobic) and oils (oleophobic) [23, 24, 26, 27].
Experiments showed that the polymers pack very densely on the cotton surface, giving rise to a thick amphiphobic
surface that is hard to breach with normal use.
These obstacles are difficult to overcome because of both the strong van der Waals attraction between SWNTs (500 eV/[micro]m) (16) and their amphiphobic
