In recent years there has been increasing interest in surface-initiated polymerization reactions because they allow to modify and control the surface properties of materials to a high extent. In this study, We modified polyimide films surface using Atom Transfer Radical Polymerization(ATRP). In here, in order to immobilize initiator for ATRP, we applied micro-contact printing(M-CP) on polyimide films. Then, surface of the PI film was functionalized with 2-bromo-2-methyl propionic acid and the graft polymerization of methyl methacrylate(MMA) was carried out using the CuBr/bpy system for ATRP. |
