本工作报告的聚合物/二氧化钛纳米复合材料的制备通过添加二氧化钛纳米粒子的聚合物基体。TiO 2纳米粒子可以有效地分散到聚合物中。纳米复合材料的折射率可以通过增加TiO 2纳米颗粒的浓度来调节。所制备的样品在可见-近红外区域，即在双光子聚合（TPP）加工波长下表现出优异的光学透明性，并且可以用于通过TPP写入三维结构。基于聚合物/TiO 2纳米复合材料的TPP加工，采用新型的折射率分辨技术制备了具有高折射率的结构。
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.
