Abstract
The surface morphology of poly(o-methoxy aniline) (POMA) films produced by spin coating was systematically studied using Atomic Force Microscopy (AFM). Initial solution concentrations, rotation speeds and relative humidity affected the final film structure and thickness. Particularly interesting is the unexpected appearance, at solution concentrations of 2% or higher, of regular patterns composed of characteristic nanometer sized holes. These patterns were caused by phase separation.
