abstract = "Vertically Aligned Carbon Nanotubes (VACNTs) are well known for
their easy production and great modification possibilities, such
as oxidation and exfoliation. Some functionalization methods can
quickly change carbon nanotubes wettabillity from
super-hydrophobic to super-hydrophilic. These last ones have great
potential for fog harvesting or other humid gas mixture
harvesting. In this work, we used these carbon nanotubes features
to develop a super-hydrophobic/super-hydrophilic patterned surface
to collect water droplets from humid air. This structure has been
designed to biomimic the Stenocara beetle one. In this work we
show that water condensation happens on self-cleaning
super-hydrophobic surface and then the droplets are pumped by the
super-hydrophilic surface. The super-hydrophobic surface was made
by deposition of polyethylene on pristine VACNTs/steel screen. The
super-hydrophilic surface was fabricated by deposition of
functionalized VACNTs on carbon fiber felt. We performed the water
collection measurement into a homemade chamber with fog-like
humidity control. The best result reached was about 30 (L/m2)/h
under controlled conditions.",
