Title:
CARBON NANOTUBE-ELASTOMER COMPOSITE MATERIAL, SEAL MATERIAL AND SEALING MATERIAL EACH PRODUCED USING SAME, AND METHOD FOR PRODUCING CARBON NANOTUBE-ELASTOMER COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/133207
Kind Code:
A1
Abstract:
Provided are: a carbon nanotube-elastomer composite material having excellent tear strength and chemical resistance; a seal material and a sealing material each produced using the carbon nanotube-elastomer composite material; and a method for producing a carbon nanotube-elastomer composite material. The carbon nanotube-elastomer composite material according to the present invention is produced by dispersing carbon nanotubes in an elastomer, wherein each of the carbon nanotubes has a diameter of 20 nm or less, the number of layers in each of the carbon nanotubes is 10 or less, the carbon nanotubes are contained in an amount of 0.1 to 20 parts by weight inclusive relative to the total weight of the carbon nanotubes and the elastomer, the elastomer is thermally decomposed and the remaining carbon nanotubes form a structure when the composite material is maintained at a temperature of 400ºC or higher for 6 hours while introducing nitrogen, and a continuous network having a Va/V0 value of 0.5 or more is formed in the elastomer wherein V0 represents the initial volume of the composite material and Va represents the volume of the structure formed from the remaining carbon nanotubes.
