  • CNT-polymer complex capable of self-doping by external stimuli and process for preparing the same
    Patent number: 9260572
    Abstract: Provided are a CNT-polymer complex and a process for preparing the same. The CNT-polymer complex includes carbon nanotubes (CNT) coated with a block copolymer of a conjugated polymer and a non-conjugated polymer, wherein the non-conjugated polymer comprises at least one monomer selected from the group consisting of styrene, butadiene, isoprene, methacryl, acryl, acryl amide, methacryl amide, acrylonitrile, vinyl acetate, vinyl pyridine and vinyl pyrrolidone in which at least one selected from the group consisting of a sulfone group, carboxyl group, acryl group and phosphate group is protected with a protective group, and provides at least one dopant selected from the group consisting of a sulfone group, carboxyl group, acryl group and phosphate group by external stimuli so that self-doping is allowed; and the complex is soluble to an organic solvent in a neutral state but is insoluble to any solvent after subjecting it to external stimuli.
