We investigated, via atomic force microscopy and transmission electron microscopy, the effect of oscillatory shearing amplitude and frequency on the interfacial morphology at reactive polymer/polymer bilayer consisting of mono-carboxylated terminated polystyrene (PS-mCOOH) and poly(methyl methacrylate-ran-glycidylmethacrylate) (PMMA-GMA). When there is no oscillatory shearing (or very small values of amplitude and frequency), the interface roughness increases with reaction time. But, the interfacial roughness under large values of amplitude and frequency becomes smaller than that without shearing, because the shearing prevents chains located away from the interface from diffusing into the interface. |
