Optical applications, perfluorinated polyimides

The combination of low optical losses over the entire WOC and high thermal, chemical, and mechanical stabilify must therefore be attained by the perfluorination of polyimides. In addition, perfluorination should deorease the dielectric constant, refractive index, and water absorption. These diaracteristics are desirable for optical and opto-electronic applications. This sftufy reports the first synthesis and the properties of perfluorinated polyimides.
