Manufacturing of conductive thin-films on PDMS for flexible electronics - any thoughts?

Does anybody know or has experience, what is the best of deposited material for PDMS? Do I need an adhesion layer between PDMS and metallic thin-film or something else? What should I know else?...

How can I measure or characterize the PDMS surfaces besides using XPS?

Does anybody have some experiences? And what kind of other methods can you suggest to characterize the structure and chemical composition of PDMS or polymeric surfaces? Thank you very much!
