Self cleaning hydrophobic and hydrophilic spray (for metal, glass,plastic etc)
Introduction of self cleaning coating
The field of self-cleaning coatings on glass is divided into two categories: hydrophobic and
hydrophilic. These two types of coating both clean themselves through the action of water,
the former by rolling droplets and the latter by sheeting water that carries away dirt.
Hydrophilic coatings based on titanium dioxide , however, have an additional property:
they can chemically break down adsorbed dirt in sunlight.The requirements for a
self-cleaning hydrophobic surface are a very high static water contact angle θ, the
condition ften quoted is θ>160°,and a very low roll-off angle,i.e. the minimum
inclination angle necessary for a droplet to roll off the surface.
Hydrophilic :
Hydrophilic simply means that the glass will attract the water and make it spread out like a
thin film. Hydrophobic means the glass will repel water and any water that comes in contact
with the glass will tend to have a minimum amount of contact with the glass and will create
spherical droplets on the surface. During the following "hydrophilic" stage rain washes away
the dirt, leaving almost no streaks, because hydrophilic glass spreads the water evenly over
its surface.
hydrophobic:
The second type of self cleaning glass is glass applied with a hydrophobic coating also
known as having the “lotus effect” which refers to the very high water repellency exhibited
by the leaves of the lotus flower. Dirt particles are picked up by water droplets due to a
complex micro and nanoscopic architecture of the surface which enables minimization of
adhesion. This form of glass works in a similar way to “Teflon” on a frying pan.
It produces a non stick surface and water will run off of this surface quickly and not streak.
Glass despite looking like a smooth surface has on a microscopic scale, peaks and valleys
which on untreated glass attract and deposit dirt and grime. The coating or applications of
this type are silica based and create a nano scale film that covers these valleys or troths.
