高折射率聚合物/纳米粒子激光雕刻材料的制备

摘要

为了提高双光子聚合立体光雕微结构的应用性,需要提高雕刻材料的折射率.TiO2粒子具有很高的折射率,通过向光敏聚合物中加入TiO2粒子,制成了聚合物/纳米粒子复合材料,有效地提高了雕刻材料的折射率.聚合物/纳米粒子复合材料的透过率和吸收率图显示,这种材料适合进行双光子聚合雕刻.%In order to improve the practicality of the photosensitive materials, the TiO2 nanoparticles are added to the photosensitive polymer,which may effectively increase the refractive index of photosensitive polymer. Experiments were made. From the transmittance and absorption curves it is shown that the synthesized nanocomposites is capable of being fabricated by using 2 PP.
