I am cleaning the PET substrate by acetone , DI , IPA , DI by sonication for 10 mint each respectively. Then dried it by nitrogen. But i am unable to deposit the PEDOT:PSS on that PET substrate using spin coating. Is there any treatment required for PET surface to make the adhesion between PET substrate and PEDOT:PSS ?
Please suggest the write way to deposit and surface treatment of PET substrate.
