Josh, Newest techniques, combination plasma vacuum dehydration and vapor deposition allows monolayer with total adhesion to the surface of any vaporizable chemical. Contact me for technical papers.

"Fluorinated polymer" probably refers to Teflon AF (amorphous fluoropolymer). You can spin it on, and a single 100 ml bottle costs around $500 or so from Dupont's "Teflon Store." It works great as an anti-adhesion layer for PDMS, but it'll never be as smooth as a nice mono-ish layer of FDTS; your mold will be wavy on the 100's of nm to single-digit micron scale. - Kevin
