Dear all, I'm looking for a polymer material which, after spinning and curing, can survive a plasma CVD deposition process at around 200-220 degrees. Not only! It should be possible afterwards to change the refractive index of this polymer either electro-optically or thermo-optically, as much as possible to tune the optical behavior of the device. Regarding the electro-optic coefficient, I don't mind if the Curie temperature is below 200deg, as long as it's possible to pole the material afterwards. I don't know if anything like this exists, but, in case, I would be grateful of any suggestion. Regards Matteo Dainese
