I want to shape polypropylene with CNC in microscale. I will bond polypropylene film on glass surface via plasma to make it stable. How can I remove my formed structure after the process. Is there any chemical that you can advice for this ?
HF will remove glass substrate for sure. However, you may try NaOH or KOH solution in methanol (as far as I remember, I could check it if you want). I have used it to etch glass some time ago, I think that longer time will completely dissolve glass.
