Spinodal wrinkling in thin-film poly(ethylene oxide)/polystyrene bilayers
Abstract
Abstract.Optical microscopy and atomic force microscopy were used to study a novel roughness-induced wrinkling instability in thin-film bilayers of poly(ethylene oxide) (PEO) and polystyrene (PS). The observed wrinkling morphology is manifested as a periodic undulation at the surface of the samples and occurs when the bilayers are heated above the melting temperature of the semi crystalline PEO (Tm = 63 $$\ensuremath ^{\circ}{\rm C}$$) layer. …
