| 제목 | The Effect of Shear Force on Reaction and Morphological Changes at Polymer-Polymer Interface |
| 초록 | In this study we investigated the effect of shear force on reaction and morphological changes at reactive polymer-polymer interface. Also, we made an attempt to find the relation changes of interface roughness with frequency and strain. The blend systems employed in this study was mono-carboxylated polystyrene (PS-mCOOH) and an poly(methyl methacrylate-ran-glycidylmethacrylate) (PMMA-GMA). PS-mCOOH was synthesized by an anionic polymerization and PMMA-GMA by a free radical polymerization. We prepared two plates of each polymer using compression molding with a smooth surface molder, then put one upon another. As soon as these two plates welds together inside a rheometer under nitrogen environment, the torque and moduli were obtained with reaction time at different frequency and strain. Through the analysis of this modulus change with reaction time, we found the effect of shear force on reaction at polymer-polymer interface. We found that the shear force help the interface to generate at low shear region, but it hinder the interface from corrugating above some amount of shear force. We analyzed the reason of these phenomena by TEM study |
