ABSTRACT: The low vapor pressure solvent 1-chloropentane was used to directly spin-
cast polystyrene (PS) films onto poly(methyl methacrylate) (PMMA) with smooth
surfaces and sharp interfaces. Interface roughness after removal of the PS layer with
cyclohexane was determined with scanning force microscopy to be <1 nm. Dynamic
secondary mass spectroscopy revealed an interfacial width below the resolution limit
of $10 nm. Large area bilayers with smooth surfaces could be created. In addition,
direct spincasting with 1-chloropentane allows the production of thin PS films
(<15 nm) and films of low molecular weight (<5 kDa) PS, all of which would be
