| 摘 要： | 研究了高温热处理对4,4′-六氟亚异丙基-邻苯二甲酸酐(6FDA)/均苯四甲酸二酐(PMDA)-4,4′-二氨基二苯醚(ODA)共聚氟化聚酰亚胺折射率的影响。随热处理温度升高,在完成亚胺化后,共聚氟化聚酰亚胺薄膜折射率的变化趋势取决于柔性链段/刚性链段(6FDA/PMDA)比例,刚性链段多,折射率随固化温度升高而增加,反之,折射率随固化温度升高而减小,即可以通过调节柔性链段/刚性链段比例实现热处理折射率的恒定。此外,只有当完成亚胺化且最高热处理温度相同时,共聚氟化聚酰亚胺折射率与含氟量才呈严格的线性关系。

| Abstract: | The influence of curing temperature on the refractive index(RI)of fluorinated co-polyimide derived from 2,2'-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride(6FDA),pyromellitic diangydride(PMDA)and 4,4'-oxydianiline(ODA)was characterized through Metricon 2010 prism coupling system.As the curing temperature(Tmc)rises,the change of RI depends on the molar ratio of rigid segment to flexible segment.If the ratio>1,RI increases with the Tmc,otherwise the RI decreases.It means that the RI of 6FDA/ODA-PMDA/OD... |
