| Résumé | In recent years, there has been an increasing interest in nano-sized star block copolymers which have hydrophobic core and hydrophilic arms since they self-assemble into a thin and stable coating on various membrane surface increasing the antifouling properties of ultrafiltration membrane system [1-4]. However, their unique structure-property relationships with respect to the local surface characteristics (hydrophilicity/hydrophobicity) by varying the size of core and arms is not yet fully understood. In this study, star-shaped block copolymers with different sizes of core and arms was prepared to study the difference in local surface characteristics of star polymers. In order to understand the detail structural information of different sized star polymers, various cutting-edge microscopic characterization methods such as scanning transmission electron microscopy (STEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM) were used. Especially, new phase mode AFM imaging method was developed for the illustration of local hydrophobicity/hydrophilicity on the surface of star polymer, and in-solution AFM imaging was performed to understand the actual arrangement of arms in water. |
