Dear colleagues, I think this question was posted in MEMS discussion quite some times ago, but anyway,does anyone have a suggestion on how to avoid sticking of PDMS to a silicon mold after it is cured? I usually used a sacrificial layer of PR on the mold, then use acetone to remove the acetone thus removing the PDMS, however, its not that good! I know that there should be an anti-stiction soln, but wondering if theres any quick method. Any suggestions would help, esp those who deal a lot with microcontact printing/soft lithography, thanks!
