表面氟化对PMMA聚合物光纤损耗性能的影响

Effects of surface fluorination on loss property of PMMA POF

研究了利用表面氟化技术制作PMMA聚合物光纤包层的可行性。从理论上证明了表面氟化能够降低PMMA聚合物表面折射率,以满足光纤对包层折射率的要求。通过实验,比较几种光纤表面氟化前后损耗值的变化,发现表面氟化后光纤损耗明显降低。因此表面氟化技术具有良好的应用前景。

The feasibility to use surface fluorination technology in the formation of the cladding of PMMA POF is studied. It is proved theoretically that the refractive index on PMMA surface can be decreased by surface fluorination, so that the surface can meet the need of fiber cladding. Through experiments the loss variation of several kinds of PMMA POF before and after surface fluorination is compared. The results indicate that the fiber loss is decreased obviously after surface fluorination. Therefore this technology has good prospect in application.
