7. Nano-Effect
After applying on smooth surfaces the nanoparticles organize
themselves in a layer and combine with the surface.
Hydrophobic surface Untreated
Surface of the surface
substrate
On smooth surfaces they cross-link with the surface. The result is that e.g. on hydrophilic surfaces, liquids can run
of like pearls and take away dirt particles.
On sucking materials like textiles or wood, the coating material infiltrates the pores and covers each fiber. Moitsture
and dirt particles can‘t permeate into the fibers because of the hydrophobicity, and run of like pearls.

remain the same. Hydrophobic textile

8. Hydrophobicity
On hydrophobic surfaces, water runs off like pearls.
A dimension for hydrophobicity on smooth surfaces is for example
the contact angle. The angle build by a liquid drop on the surface
to this surface is called contact angle.
A surface is called hydrophobic when the contact angle is above
90° compare to water.
Measurement of a contact angle (Kontaktwinkel)
Waterdrops run down and take The contact surface for dirt This surface is not hydrophobic and
away dirt particles on inclined particles is extremly reduced by has no microstructure. It is more
surfaces. the microstructure of the surface. moistened by water, and dirt particles
can adhere.

11. Photocatalytic self-cleaning coating for glass and plastic surfaces
O2 H2O2 Product for Glass
UV-Light
HO*  Especially suitable for facades, weather side,
TiO2 e- + h+ because the photocatalysis need water in
H2O sufficient quantity
 Improvement of light efficiency
 The surface tension against condensation water
is increased above the air/water-value, hence
e- : elektron results a total flowing of the condensation water.
h+ : hole
Photocatalysis-Process
 Titanium dioxids is a semiconductor, UV-light
generates electon-hole-pairs, that diffuse to the
surface
 Particularly the holes have a high oxidation effect,
they turn water (H2O) into OH-radicals.
 These radicals generate hydrogen peroxide together
with oxigen
 Organic substances can be decomposed
