文摘

A new approach to the preparation of TiO₂ nanoparticles embedded in organic films is described. This room-temperature method is based on a Langmuir–Blodgett standard procedure using an aqueous subphase in which TiO(C₂O₄)₂²⁻ is dissolved. Spectroscopic investigations on the subphase show that TiO₂ nanoparticles are dispersed in the solution. Careful X-ray photoelectron spectroscopy characterisation of Langmuir–Blodgett films reveals that those particles are transferred into the interior of the films during growth of the n-octadecylamine layers.
