The arrested hydrolysis of titanium tetraisopropoxide by millimolar concentrations of water in a mixture of chloroform and 1-propanol in the presence of hexadecyltrimethylammonium bromide and tetramethylammonium hydroxide resulted in the formation of stable dispersions (sols) of nanocrystalline (18-22 A diameter) TiO[sub 2]. Spreading the sols on water surfaces in a Langmuir film balance produced monoparticulate TiO[sub 2] films. Heat treatment of a given sol prior to dispersion on the aqueous subphase resulted in nanocrystalline monoparticulate TiO[sub 2] films with reduced interparticulate distances. 14 refs., 7 figs.
