Popis: Liquid phase deposition method is applied to one-step production of a hybrid material composed by dopamine(DA) and TiO 2 anatase. An optimized amount of the enediol derivative is added to a fluoride titania precursor aqueous solution in order to entrap this modifier within the growing TiO 2 , yielding a DA/TiO 2 nanocomposite material. Uniform, well-adhered and brown-colored thin films are deposited on indium tin oxide covered glass substrate. The DA/TiO 2 hybrid material has been characterized by infrared spectroscopy, electronic microscopy, X-ray diffraction and UV–vis spectroscopy. The formation of the hybrid material seems to be reasonably explained by linkage of different TiO 2 nanocrystallites taking advantage of both enediol and amine groups of DA.
