Abstract: This core-shell composite (10) is provided with a core (11) formed from a porous carbon body having a large number of pores from the interior through to the surface, and a shell layer (12) formed from conductive polymer nanorods (12a) that extend outward from the cavities of the pores (11a) on the surface of the core. The present invention provides the core-shell composite (10), to which electrolyte ions can be efficiently adsorbed or doped, a method for producing the core-shell composite, as well as an electrode material, a catalyst, an electrode, a secondary battery and an electric double-layer capacitor that use the core-shell composite.

Abstract: The present invention provides a conductive material including: (A) a ?-conjugated polymer, (B) a dopant polymer which contains one or more repeating units selected from “a1” to “a4” respectively shown by the following general formula (1) and has a weight-average molecular weight in the range of 1,000 to 500,000, and (C) one or more salts selected from the group consisting of a metal salt of carboxylic acid, a metal salt of ?-diketone, a metal nitrate, a metal carbonate, a metal bicarbonate, a metal halide, and a metal hydroxide, with the metal being selected from the group consisting of cesium, rubidium, barium, and strontium. There can be provided a conductive material which is neutral and highly suitable for a printer, superior in film-formability, and also can form a conductive film having high transparency and conductivity, excellent flexibility and flatness when the film is formed from the material.

Abstract: An aqueous composition including: a conductive metal nanoparticle having an organic compound disposed on a surface of the conductive metal nanoparticle; a conductive metal nanowire; and a solvent including water and optionally an alcohol.
