Synthesis and Characterization of Multifluorinated Aromatic Polyimides

摘要

@@Fluorinated polyimides (FPls) have attracted much attention in the last decades owing to their excellent combination of thermal, mechanical, dielectric and chemical properties, which make them good candidates for microelectronics applications. In addition, FPIs usually exhibit outstanding optical transparency and low optical loss in the range of the optical telecommunication wavelengths, which expand their applications to optical inter-connection and telecommunication fields as optical waveguide circuits, thermo-optic switches,optical filters, and linear polarizers.In this research, the novel multifluorinated aromatic polyimides were investigated, aiming at development the polymeric optical waveguide materials. The solubility, thermal and mechanical properties, electrical and dielectric properties, especially, the optical properties of the multifluorinated polyimides were investigated.
