Hydrophilicity
|
Generally,
organic compound
is absorbed on the
material's surface,
so to wash it, the
use of detergent
is necessary, But,
photocatalyst-coated
surface with illumination
can eliminate dirt
and thanks to its
hydrophilicity,
it can also separate
pollutants like
car exhausts and
smoking wastes from
the surface, So
it can be used for
automobile body
coat, store signs,
building's windows,
exiternal construction
materials and guardrails.
