METHOD OF MANUFACTURING IONOMER-COATED CATALYST-SUPPORTING CARBON NANOTUBE

摘要

A step of preparing a catalyst-carrying carbon nanotube, a step of preparing a first ionomer solution, a step of bringing the catalyst-carrying carbon nanotube into contact with the first ionomer solution to coat the catalyst-carrying carbon nanotube with an ionomer And a drying step of drying the catalyst-carrying carbon nanotubes coated with the ionomer, wherein the ionomer-coated carbon nanotubes are subjected to the ionomer coating step and after the ionomer coating step and after the ionomer coating step, Before the process, the ionomer is preferentially removed from the ionomer adhered to the end portion of the carbon nanotubes adhered relatively more than other portions among the ionomers that are unevenly adhered in the thickness direction of the layer comprising the catalyst-supporting carbon nanotubes coated with the ionomer Characterized in that it has an ionomer removal process, characterized in that the ionomer- Process for producing a supported carbon nanotubes.
