Abstract

Abstract : Controlled polymerization and self-assembly of novel block copolymer electrolytes. Abstract : Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization of 4-styrenesulfonyl(trifluoromethylsulfonyl)imide potassium salt (SKTFSI) in N, N -dimethylformamide (DMF) solution was carried out using 2-(dodecylsulfanylthiocarbonylsulfanyl)-2-methylpropionic acid (DDMAT) as a reversible chain transfer agent in the presence of 2, 2′-azobisisobutyronitrile (AIBN) at 65 °C in an inert atmosphere. We showed both homopolymers and well-defined polyelectrolyte diblock copolymer systems could be prepared through the direct polymerization of the charged SKTFSI monomer. To produce Li-ion polyelectrolytes, a cation exchange methodology ( e.g. K + → Li + ) was used. Self-assembly of single-ion diblock copolymer thin films consisting of a Li-ion conductive PSLiTFSI block associated with a glassy polystyrene block is also demonstrated.
