Hi guys, this is my first post    ( I am from Mexico, so, sorry for my bad english  hope you understand, I'm going to do my best )

I have been investigating about nanomaterials and self-cleaning windows, and I found it really exciting, so I would like to try to make my own coating for Self Cleaning Windows 

According to what I have found surfing the web, I need to use Titanium Oxide in water dispersion, I have seen some videos on Youtube and it really seems too easy to be true    

Here is a link from a provider of TiO2 in water dispersion....

Specifically, I would like to know what else do I need, and how much Titanium Oxide do I need? (wt%)

I am not a chemist, so, please correct me 

Thank you very much

Your post sparked some interest so I looked it up on WIKI
http://en.wikipedia.org/wiki/Self-cleaning_glass
and noticed this

The first self-cleaning glass was based on a thin film titania coating.[3]

Looking at the footnote title

Y. Paz, Z. Luo, L. Rabenberg, and A Heller, "Photo-oxidative Self-cleaning Transparent Titanium Dioxide Films on Glass", J. Mater. Res., 10, 2842–2848 (1995).

The date seems to denote that all of this is recent and may be still under patient.
Therefor you might find the information you are requesting proprietary and not readily available to the public.

20 years are a long time for technology. Google finds 100,000 pages matching
"Self-cleaning window" "titanium dioxide"

And because US patents want a workable description of an invention... 10 pages matching
"Self-cleaning window" "titanium dioxide" "US patent"
the counterpart of protection is that a patent makes the knowledge immediately public.
