Add to ORKGThin films of polystyrene (PS)/polymethylmethacrylate (PMMA) blends were made by casting from solutions with solvents of varying vapor pressure. Solvents used were chloroform, toluene and dichloromethane. Spin coating was carried out at varying speeds yielding films of different thickness. Atomic force microscopy and phase-sensitive acoustic microscopy were used to investigate the effects of spin speed and solvent vapor pressure on morphology. The domains formed due to lateral phase separation proved to be strongly influenced by vapor pressure with completely different surface structures for the three solvents. The films cast from high vapor pressure solutions displayed an increased surface roughness. Surface morphology is explained by the ...
