Hi,
I don't know exactly the processes you described. But I know that PDMS will
swell in acetone. It might caused by the mechanical strain between PDMS and
your substrats.

Subject: [mems-talk] PDMS adhesion

I found in my experiments that acetone is good to release bonded PDMS
surfaces. But I do not how it works. Does anyone have experience or can
provide some references what exactly acetone does to the interfacial
adhesion of PDMS?
