高热稳定性氟化聚酰亚胺的合成及在热光开关中的应用
Synthesis of Fluorinated Polyimide with High Thermal Stability and Its Application for Thermo-optic Switch
摘要
Abstract
A novel material fluorinated hyper branched polyimide ( FHBPI) was synthesized for using in thermo-optic waveguide switch applications. This material has high thermal stability. Differential scanning calo-rimeter(DSC) and thermo-gravimetric analysis(TGA) were taken to evaluate the glass transition temperature ( Tg ) and the thermal decomposition temperature (Td,5%). The results indicate that Tg and Td,5% are 189 and 596 ℃, respectively. The film quality of FHBPI is excellent. The atomic force microscopy (AFM) exhibits the surface roughness of FHBPI film, which is 0. 54 nm. FHBPI has a high optical transparency in the infrared communication region. The thermo-optic switch device was designed, fabricated and tested by FHBPI. The rise time and fall time of the switch are 267. 9 and 254. 1 ΜS, respectively.关键词
