Abstract
The invention relates to a method for preparing a colloidal nanoparticle solution, including: (a) dissolving a titanium-oxide precursor, referred to as a precursor, in one or more solvents, referred to as precursor solvents; and (b) chemically converting, preferably by means of hydrolysis, said titanium-oxide precursor and said precursor solvent into a colloidal-solution solvent so as to form titanium-oxide nanoparticles that are dispersed in the colloidal-solution solvent, said colloidal solution having a dynamic viscosity of between 4 and 54 cP at 20° C. and 101,325 Pa.
