Abstract: Disclosed is a carbon material, such as a carbon nanotube, into which a boron atom and/or a phosphorus atom is/are introduced while maintaining its characteristic structures and functions and a method for producing the same. The carbon material of the present invention is one in which a boron atom and/or a phosphorus atom is/are introduced into part of carbon atoms composing the carbon material, and can be produced by a method for producing a carbon material including the steps of: bringing a carbon material into contact with a fluorination treatment gas containing a fluorine-containing gas, thereby subjecting a surface of the carbon material to fluorination treatment; and bringing the carbon material after the fluorination treatment into contact with a boronization treatment gas containing a boron-containing gas, thereby subjecting to boronization treatment and/or into contact with a phosphorization treatment gas containing a phosphorus-containing gas, thereby subjecting to phosphorization treatment.

Abstract: A cross-linked structure of a carbon material is excellent in mechanical strength, such as tensile strength. The carbon materials such as carbon nanotube, graphite, fullerene, and carbon nanocoil, are cross-linked with each other. The carbon materials are cross-linked through a linking group derived from a nucleophilic compound having two or more nucleophilic groups in the molecule.

Abstract: To provide a novel immobilized product in which a carbon material and/or a silicon material is/are immobilized on a base material surface by a chemical bond via a linking group, and a method for producing the same. The immobilized product is an immobilized product in which a carbon material is immobilizing on a surface of a base material, wherein the carbon material is chemically bonded on the surface of the base material via a linking group, and the linking group is at least one selected from the group consisting of a —NH group, a —NH—R1—NH group, a —SO group, a R2 group, a —O—R3—O group, and a R4 group (in which the R1 to R4 each independently represent at least one selected from the group consisting of a chain alkyl group, a cyclic alkyl group, a chain alkenyl group, a cyclic alkenyl group, a chain alkynyl group, etc.).
