Title:
CARBON TUBE AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3440591
Kind Code:
B2
Abstract:
PURPOSE: To obtain a carbon tube having a specific shape, which could not be produced hitherto and useful for composite materials, electroconductive material, etc., by selecting a carbon tube having a specific size.
CONSTITUTION: A carbon tube having 10nm to 1μm diameter and 1-100μm length is selected. This carbon tube is obtained by applying an organic material (e.g. furfuryl alcohol) to the inner wall of an inorganic substance having nearly linear pore (e.g. aluminum anodic oxidation film), heating the organic material- coated inorganic substance and then dissolving and removing the inorganic substance by hydrofluoric acid treatment. A carbon tube opened in both ends and having ≤1μm diameter and 1-100μm length is selected. This carbon tube is obtained by carbonizing gaseous hydrocarbon (e.g. propylene) in a gas phase, depositing carbon thin film onto pore inner wall and then dissolving and removing the inorganic substance.
