dc.description.abstractEnAmphiphilic block copolymers composed of a poly(3-hexylthiophene) (P3HT) segment and a sulfonated polystyrene (PS-stat-PSS) sequence with well-defined and easily tunable structure were synthesized through Grignard metathesispolymerization (GRIM), RAFT polymerization and sulfonation of PS. Because of the hydrophilic nature and ionic conductivityof the PSS segment, such copolymer shows good solubility in water and high conductivity ∼1 S/m in form of dry film.Conductivity can be further enhanced with the addition of single-walled nanotubes (SWNTs). The present amphiphilic blockcopolymer enables efficient unbundling and stabilization of SWNTs in water. With the help of an original microfluidic techniquereferred to as microf luidic pervaporation, we investigated the concentration process of SWNT/copolymer suspensions up to dry films and obtained a complete phase diagram which reveals the aggregation of SWNTs during the concentration process in a given concentration range. High conductivity of about 370 S/m is achieved for SWNT/copolymer nanocomposites at highconcentration of SWNTs. The microfluidic pervaporation method is also shown to provide a direct determination of the CNT percolation threshold.
