In star polymers, the arms located near the center exhibit low mobility due to dense packing, while those in the outer sphere exhibit high mobility due to the availability of free space. Taking into account these features of a star polymer, in this work, we have synthesized novel star-shaped block copolymers, poly(methyl methacrylate)-block-poly[poly(ethylene glycol) methacrylate] (PMMA-b-PPEGMA)8 via atom transfer radical polymerization using octafuctional silsesquioxane core as a initiator. The central PMMA segment contributes to the mechanical strength of the solid film, and the outer PPEGMA segment not only results in a high electrical output but also provides flexiblility to the solid polymer film. A detailed characterization of the polymerizations will be given in the meeting. |
