I want to use gold electrode on the PDMS.
We used an e-beam evaporator to deposit gold electrode on the PDMS using the recipe Ti 5nm, gold 80nm, right after using e-beam evaporator, there is no problem.
But when I dropped the gelatin solution(based DI water), after 1 hour there are some cracks adjacent to the gelatin droplet. So I can not measure my sample.
I think we need to enhance the adhesion between the gold and the PDMS.
How can I solve this problem??
