The study of interpenetration width between dPS films and grafted PS layers with varied chain length |
초록 |
In polymer thin film system, the type of interfacial interaction is a critical parameter to determining the thermal and physical properties of polymer films. Interestingly, the interfacial energy of grafted brush layer is remarkably altered by simply controlling brush’s grafting density, which has been referred to as autophobic behavior. In this study, we controlled the molecular weight of hydroxyl-functionalized polystyrene (HO-PS) to modify the surface in a standard Si wafer. Deutrated polystyrene (dPS) was prepared on the PS brush layer to enhance the neutron contrast between the brush layer and top polymer films. The interfacial widths between layers were calculated by Neutron Reflectivity (NR) experiments to define the interfacial interactions between the PS brush layer and top dPS polymer films. |
