Solution processable TiO₂ nanoparticles capped with lauryl gallate

In this work, a single-step synthesis route to prepare lauryl gallate capped TiO 2 nanoparticles has been established. Powder X-Ray diffraction analysis shows anatase as the predominant inorganic phase. UV-vis and FT-IR spectroscopy characterization denotes that lauryl gallate molecules are covalently linked to the particulate titania core through the enediolate group. The as prepared powder is easily dispersable in common organic solvents, such as tetrahydrofurane, methylethylketone and n-butanol, showing good stability under ambient atmosphere. This solution processable precursor facilitates thin film deposition on glass substrates. The capping gallate derivative also facilitates preparing translucent TiO 2-polystyrene composites. © 2012 Elsevier B.V.
