| Abstract | Nano-sized core shell star block copolymers which have a hydrophobic core and hydrophilic arms have attracted considerable attention in recent years since their high areal density generate a thin and stable coating on various membrane surfaces through a self-assembly process for better antifouling properties of ultrafiltration system. This unique structure of star block copolymers makes it stick to the hydrophobic surface and render highly hydrophilic membrane surface for the better antifouling property. Therefore, complete understanding of its detail structures depending on temperature is the key of utilizing this product in membrane applications. In this study, a novel ultra-thin coating consisting of self-assembled star-shaped block copolymers which have different types of arms was used to increase the antifouling properties of membrane. In order to understand the relationship between the surface structure of coating and antifouling properties, various cutting-edge microscopic characterization methods such as scanning electron microscopy (SEM), focused ion beam (FIB), transmission electron microscopy (TEM) and atomic force microscopy (AFM) were used. Especially, new phase mode AFM imaging was introduced for the illustration of local hydrophobicity/hydrophilicity on the surface of star polymer (SP) coated membrane. |
