Abstract: Chemically modified carbon nanotubes composed of carbon nanotubes (such as multiwall carbon nanotubes) having carboxyl groups on the surface thereof and polymeric aniline (such as 3- to 300-meric aniline) bonding thereto through the amide linkage. The chemically modified carbon nanotubes exhibit good affinity with organic solvents and readily disperse into organic solvents.

Abstract: A method for manufacturing a polyaniline by preparing an aniline mixed solution in which an antirust additive and at least one of aniline and aniline derivatives are mixed and polymerizing at least one of the aniline and the aniline derivatives by adding a polymerization initiator to the aniline mixed solution, polyaniline obtained by the method, a polyaniline-containing solution, and a coating material containing the polyaniline.

Abstract: In an antirust treated metal base material in accordance with the present invention, a coating film containing insulating polyaniline in a highly oxidized state (PE state) is formed on the surface of a metal base material. A method for antirust treatment of the surface of a metal base material includes a process of forming a coating film containing insulating polyaniline in a highly oxidized state (PE state) on the metal base material surface. According to the present invention, an antirust treated metal base material, in which the coating film of an insulating polyaniline system containing no dopants exhibits strong corrosion inhibition effect, and a method of antirust treatment for the metal base material are provided.

Abstract: A conductive polyaniline composition of a substituted or unsubstituted polyaniline complex and a compound with a phenolic hydroxyl group dissolved in an organic solvent substantially immiscible with water that is capable of producing a molded article possessing high conductivity.
