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.
Flexible organic photovoltaics have gained increasing interests during the last decades. Toward increasing the
efficiency and decreasing the cost per Watt, they are on their way to the market. The approach of laser patterning
technology has been expected to motivate the industrialization of organic photovoltaics. In this paper high repetition
picosecond laser radiation fabricated trenches of ITO on flexible PET (Polyethylene terephthalate) substrate are
presented. In order to obtain clean removal ITO layer without damaging PET substrate, 1064nm, 532nm and 355nm
wavelengths with different laser fluencies and scanning strategies are applied and optimized. The results reveal the
different principles for ablation of ITO layer with different wavelengths. The ITO layer is successfully and selectively
removed by 1064nm laser radiation with 0.63J/cm2 fluence and 4m/s scanning speed.
