I think methylene chloride also works well.
My advice is to put both components into a bottle,
and roll the bottle overnight. The polycarb dissolves and
the polymer 'relaxes' in the solvent making a thin film easier to obtain. I
would Not suggest doing a 5-minute dissolution and then using it.
Good Luck.

Subject: [mems-talk] Thin films of polycarbonate
Dear mems-researchers;
I would like to spin coat thin films (about 100 nm thick) of polycarbonate
(Bayer MAKROLON CD2005) on a silicon substrate using cyclohexanone as
solvent.
As I have problems to dissolve the polycarbonate in cyclohexanone, I have
some questions to ask:
- Firstly, do you know what can I do to obtain a homogenous solution with
this solvent?
- Secondly, does a better solvent than cyclohexanone able to dissolve the
polycarbonate exist?
- Finally, do you know if a commercial solution exist such as polycarbonate
already dissolved in a solvent (which solvent?) for spin coated thin films?
Thanks a lot.
Yours sincerely,
Tatiana Pinedo
