제목 | Morphological development at the interface of polymer/polymer bilayer with in-situ compatibilizer under electric field |
초록 | In this study, electric field was applied to reactive bilayer thin films consisting of poly(methyl methacrylates-ran-glycidylmethacrylate)(PMMA-GMA) and polystyrene (PS) with various amounts of in-situ compatibilizer of mono carboxylic acid end-functionalized PS (PS-mCOOH). The fast growing wavelength (λmax) of the interfacial fluctuation under electric field was changed with various amount of PS-mCOOH, because the interfacial tension between PMMA-GMA and PS decreased due to the PMMA-g-PS. The relationship between wavelength and film thickness holds for reactive bilayer regardless of the amounts of reaction. We measured the interface and surface and surface morphology by using atomic force microscope (AFM), optical microscope (OM) and field-emission scanning electron microscope (FE-SEM). We could obtain the size scale of pillar down to submicron by controlling the amount of the in-situ compatibilizer and film thickness.
