| A
hydrophily means to get wet easily on surface condition.
Such as made waterdrop on something surface after
rain that water shedding condition. The hydrophily
is spread water and looks like water film on the
surface. |
|
|
| The
droplet is spread on photocatalyst coating surface
why angle of contact of water is nearly 0 when activate
TiO2 to illuminate the light. Various material surface
conditions can be changed to hydrophily to use this
phenomenon. |
|
|
|
|
|
Some
dirt put on the surface that is able to flush
away together with water (such as rain) on
hydrophilic surface how is get into the dirt
and strike up it.
This effect is used flush away on a surface
of building external wall, cool down building
wall to wrap little water at summer season,
etc.
|
|
|
| By
using the hydrophily of photocatalyst, it
is found to be useful for curtailment of maintenance
expense, improvement of electricity expense,
landscape management, environmental protection,
etc. |
