I have done tio2 coating on the glass by spin coating but its adhesive property is not good even though I have done glass treatment. Can you please suggest some binders which won't affect the transmittance and photocatalytic properties.
TiO2 is the main pigemtn in most commercial paints. You could try using a polymer blend similar to those used in paints. This should adhere quite well to glass, provided it is thoroughly cleaned prior to application.
