Abstract

This work reports the preparation of polymer/TiO₂ nanocomposite by adding TiO₂ nanoparticles to the polymer matrices. TiO₂ nanoparticles can be effectively dispersed into the polymer. The refractive index of the nanocomposites can be tuned by increasing the concentration of TiO₂ nanoparticles. The prepared samples exhibit excellent optical transparency in the Vis-NIR region, i.e. at two-photon polymerization (TPP) processing wavelength, and can be used to write threedimensional structures by means of TPP. Structures with high refractive index have been produced with the novel ultrahigh resolution technology based on TPP processing of polymer/TiO₂ nanocomposites.
