Low Refractive Index Fluoropolymer(HELP) for thin film coating
(OP)
I'm searching for candidate polymers that possess very low refractive index (~1.3 - 1.35) in the visible portion of the spectrum. Polymers/Ionomers that could be dissolved in solvents to get even relatively thin, coatings preferred. Polymer material is expected to act as an encapsulant. "Transparency" is pretty critical as well. I would really appreciate your inputs/feedback.

For now I would suggest you look at these places that list specialty monomers and polymers:

Searching Google for "fluoropolymer refractive index 1.3" gave some good hits including:

You could plasma polymerise a very thin coating of fluoropolymer onto your substrate for example using the atmosperic plasma technique of Dow Corning as seen here:

I know they can do 30nm thick coatings of fluoroacrylates.
There is not any memory with less satisfaction than the memory of some temptation we resisted.
