Hi Amirali. One way is to grow your graphene pattern on a silicone wafer by patterning the catalyst before CVD. Spin a layer of PDMS onto a glass slide and just before it is cured use the stickiness to lift the graphene off the first wafer. See the work of Yael Hanein from Tel Aviv. She did something similar with patterned carbon nanotubes.

I prefer the work of Philip Kim of from Columbia Uni.. However, I have to say that from my experience, it is quite hopeless if you want to further transfer graphene from PDMS to another surface because graphene layer will be torn into small pieces (I believe it also happen on pdms surface).
