The
synthesis of polysiloxane nanotubes using trifunctional organosilanes
is reported. Tubular nanostructures were formed via a chemical vapor
deposition technique at room temperature when ethyltrichlorosilane
is used or via a liquid phase method when methyltriethoxysilane is
used as precursor. In the chemical vapor deposition process the shape
of the tubes was controlled by changing the water content in the reaction
chamber prior to coating. The diameter varied between 60 and 4000
nm. While in the case of the liquid phase method nanotubes with very
high aspect ratios of 800 are produced. Parameters, such as length
and diameter of the various tubes, were investigated using scanning
electron microscopy and transmission electron microscopy. Additionally,
the chemical composition of produced structures was analyzed using
attenuated total reflectance-infrared and energy-dispersive X-ray
spectroscopy. Glass substrates coated with such structures exhibit
extreme superhydrophobic properties.
