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
