There is provided a heat-conductive flexible sheet that is formed of a non-silicone material and excellent in flexibility as well as durability such as heat-aging resistance, hydrothermal resistance, and thermal shock resistance, and a heat dissipation structure using the same, as well as a resin composition that exhibits excellent handleability in the kneading step in producing a heat-conductive sheet and can be suitably used as a binder material for a heat-conductive flexible sheet. A resin composition comprising a blocked urethane prepolymer, a predetermined epoxy compound, and a curing catalyst, the blocked urethane prepolymer being a reaction product of an aliphatic diisocyanate compound and a hydrogenated polybutadiene polyol having a hydroxy group at each of both ends, wherein the reaction product has at an end thereof an isocyanate group blocked with an aromatic hydroxy compound; a heat-conductive flexible sheet formed of a cured product of a mixed composition comprising the same and a heat-conductive inorganic filler; and a heat dissipation structure using the same.

Disclosed is an antibacterial nanofiber which comprises a polymer having an electron-withdrawing group and/or an electron-withdrawing atomic group and has an average fiber diameter of not less than 1 nm and less than 1000 nm, wherein the ratio of the binding energy of the minimum unit of the polymer at 25&#xb0; C. to the binding energy of the electron-withdrawing group and/or the electron-withdrawing atomic group contained in the minimum unit of the polymer at 25&#xb0; C. is 0.13 or greater. The nanofiber has an antibacterial activity by itself, and therefore can exhibit an antibacterial activity without the need of adding any antibacterial agent.

Provided are a carbon catalyst for decomposing a hazardous substance that effectively decomposes hazardous substances such as aldehydes, a hazardous-substance-decomposing material, and a method of decomposing a hazardous substance. The carbon catalyst for decomposing a hazardous substance is a carbon catalyst having a catalytic activity for decomposing the hazardous substance. The hazardous substance is, for example, a volatile organic compound such as aldehydes or a malodorous substance such as a sulfur compound. The method of decomposing a hazardous substance, is a method including decomposing the hazardous substance with the carbon catalyst for decomposing a hazardous substance or with a hazardous-substance-decomposing material containing the carbon catalyst for decomposing a hazardous substance.
