TEHRAN (FNA)- Iranian researchers
from Institute for Color Science and
Technology formulated a self-cleaning
ink and printing titania nanoparticles
on glass by using inkjet printers.
Cleaning glasses, especially in today's tall
buildings and towers, is very challenging
and expensive. At the same time, glass or
surfaces coated with titanium dioxide
photocatalyst show self-cleaning
properties under the sun radiation.
Dr. Maryam Hosseinizari, the executor of
the plan, stated, "Taking into
consideration the fact that printing with
inkjet printers on ceramic and tile
industry have become common recently,
this research was carried out in order to
determine the self-cleaning properties of
the glass after stamping titania
nanoparticles on the glass surface by
using inkjet printer."
"The pre-prepared ink was printed on the
glass. Then, the glass was dried and the
relation between the thickness and self-
cleaning power was evaluated and
discussed," she continued.
Hosseinzari pointed to other advantages
of the plan, and said, "Contrary to screen
printing method, the wastage of material
is significantly reduced in this method.
However, it must be pointed out that
there are limitations for the direct use of
pigment in printing ink."
"Among the limitations, mention can be
made to the fact that the pigment should
be synthesized in a fine morphology and
small size, and it should have
homogenous distribution and stability so
it will not block the ink vessel. Therefore,
the synthesis method is highly
important."
Results of the research have been
published in December 2012 in Journal of
the European Ceramic Society, vol. 32,
issue 16, pp. 4271-4277.
