The adhesiveness of the perfluorinated polyimides is thus equivalent to that of partially fluorinated polyimides used for single-mode waveguide fabrieations. Their dielectric constants (e) at 1 kHz and average relfactive indexes are as low as those of the partially fluorinated polyimides. This is primarily because the fluorine content of perfluorinated polyimides is comparable to that of partially fluorinated polyimides. Hougham et investigated the fluorination effect on dielectric 

These characteristics show that perfluorinated polyimides are promising materials for waveguides in integrated optics and optical interconnect technology. The thermal, mechanical, and optical properties of perfluorinated polyimides can be controlled by copolymerization in the same manner as partially fluorinated polyimides.
