  摘要：

  我们对用于柔性光波导的高氟化液态预聚物及其紫外固化薄膜进行了评估。Two liquid prepolymers, 2,3,5,6,2′,3′,5′,6′-octafluoro-4,4′-bis-[2-{2-[1,1-difluoro-2-(2,3,5,6-tetrafluoro-4-vinyl-phenoxy)-ethoxy]-1,1,2,2-tetrafluoro-ethoxy}-2,2-difluoro-ethoxy]-biphenyl (7) and 2,3,5,6,2′,3′,5′,6′-octafluoro-4,4′-bis-[2-(2-{2-[1,1-difluoro-2-(2,2-(2-{2-[1,1-二氟-2-(2,3,5,6-四氟-4-乙烯基-苯氧基)-乙氧基]-1,1,2,2-四氟-乙氧基}-1,1,2,2-四氟-乙氧基)-2,2-二氟-乙氧基]-联苯 (8) 由十氟联苯、2,3,4,5,6-五氟苯乙烯和氟化三乙二醇或氟化四乙二醇合成。这些预聚物经光固化后可形成柔韧透明的薄膜。用这些预聚物制成的薄膜的折射率受其混合成分的控制，在波长为 1.31 μm 时为 1.417-1.437。在波长为 1.31 μm 时，用预聚物 7 和 8 制备的薄膜的光学损耗分别为 0.25 和 0.23 dB cm-1。薄膜在 400 °C 以上的温度下具有热稳定性。用预聚物 7 和 8 制备的薄膜的极限应力、初始模量和伸长率分别为 17.1 兆帕、1.25 千兆帕和 1.5%，以及 12.3 兆帕、0.44 千兆帕和 6.9%。用这些预聚物制造的光波导无需任何基底膜即可弯曲，弯曲半径为 1.5 毫米时的光损耗低于 0.2 分贝。通过研究用液态预聚物制造的柔性光波导中的光传输，我们确定液态预聚物可能是柔性光波导应用的理想候选材料。

  A composition for forming film having wrinkle structure and a method of forming the film are disclosed. The composition includes photo-curable agent and photoinitiator dissolved in the photo-curable agent. The cut off wavelength of light transmittance of the photo-curable agent is greater than the cut off wavelength of light absorbance of the photoinitiator. Photo-cured thin film is formed at the upper portion of composition layer at an initial time period of irradiation. By subsequent contraction, the photo-cured thin film forms wrinkles. The wrinkle structure is controlled by the relation of the cut off wavelength of light transmittance of the photo-curable agent and the cut off wavelength of light absorbance of the photoinitiator, the photo-curing rate of the composition and the thickness of the composition layer, and the photoinitiator concentration, etc., before photo-curing. The film may increase the emission efficiency of LED and OLED and the sensing effect of sensor.
