pdms question

hi labmembers,

For those of you with particularly deep insight into pdms, i was wondering if there's a treatment method on the pdms surface or on the surface of something like mylar (transparency film), that reduces the sticky factor of the pdms when attached to this mylar. I'd like the pdms and mylar surface to still be optically transparent in the visible after the particular evaporation or chemical treatment method.

i learned from a colleague that kapton can be chemically placed on the pdms but this compromises the optical property somewhat & the lifetime is poor (~a few weeks).

Regards,
Sonny
