Synthesis and Nanophase-Separated Morphology of a Diblock Copolymer of Polypentafluorostyrene-b-Poly(methyl methacrylate) by Atom Transfer Radical Polymerization

Abstract:

We synthesized a symmetric, fluorine-containing diblock copolymer of polypentafluorostyrene-b-poly(methyl methacrylate) (PPFS-b-PMMA) by atom transfer radical polymerization (ATRP). The PPFS macroinitiator was also synthesized by ATRP by using 1-phenylethyl bromide initiator. The chemical structure of the polymer was confirmed by GPC, 1H-NMR and DSC measurements. Due to the chemical dissimilarity between the PPFS and PMMA blocks, the microphase-separation was occurred during annealing at high temperature, displaying a lamellar morphology with a thickness of approximately 35 nm.
