Title:
MODIFIED CARBON NANOTUBE FOREST, CARBON NANOTUBE ALIGNED AGGREGATE, GAS-PERMEABLE SHEET, CATALYST ELECTRODE FOR FUEL CELLS, ELECTROCONDUCTIVE MEMBER, THREAD-LIKE ELECTROCONDUCTIVE MEMBER, INTERLAYER HEAT-CONDUCTIVE MATERIAL, AND METHOD FOR PRODUCING MODIFIED CARBON NANOTUBE FOREST
Document Type and Number:
WIPO Patent Application WO/2022/137950
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a modified CNT forest in which a CNT forest is modified with another substance; a CNT aligned aggregate which comprises a spun product of the modified CNT forest; a gas-permeable sheet which comprises the CNT aligned aggregate; a catalyst electrode for fuel cells, which is provided with the gas-permeable sheet; an electroconductive member and a thread-like electroconductive member, each of which comprises the modified CNT forest or the CNT aligned aggregate; an interlayer heat-conductive material which comprises the electroconductive member; and a method for producing the modified CNT forest. The modified carbon nanotube forest (40) according to the present invention comprises carbon nanotubes (50) that are aligned in a predetermined direction and microparticles (70) supported on the carbon nanotubes (50), can be spun, and preferably has a ratio R of 3 or more, in which the ratio R is defined by formula (1) below using an adjacent gap distance D1 between the carbon nanotubes (50) and an average particle diameter D2 of the microparticles (70). It is preferred that the microparticles (70) have electroconductivity. (1): R = D1/D2
The adjacent gap distance D1 is expressed by formula (2) using the number density A (unit: carbon nanotubes/m2) of the modified carbon nanotube forest (40) and the average diameter D3 of the carbon nanotubes (50). (2): D1 = A-1/2-D3
