Some years ago I did some research on the use of foils to make lab-on-a-chip devices. To makes some experiments work (i.e. like FISH [0]), one needs formamide (although there are alternatives). Kapton [1] turned out to be one of the very few polymers to be able to withstand it, and also ethanol. I found out is was used for solar sails as well [2] (as original PDF, url is not working atm).
If we can read the article again, I bet it will come up.
