The incorporation of nanosized inorganic particles into a polymeric matrix represents one of the most difficult problems in the fabrication of nanocomposites. The success in the manufacturing of such materials can be achieved only if the aggregation of particles is avoided, which is essential when high transparency is required, as for optical device applications. Here, a method is described for the preparation of a polymeric nanocomposite, containing a well-dispersed red pigment synthesized by adsorption of an organic dye onto nanosized titania particles. The system can be easily deposited on glass plates by spin coating, yielding homogeneous, low-defect thin films of high color purity and transparency, which can be used as color filters for liquid crystal displays. These films were characterized by scanning electron microscopy and UV/vis spectro-photometry, and their mechanical properties were evaluated by studying the damage induced from ultrasound.
