Title:
METHOD FOR PRODUCING SPHERICAL NANOCARBON FIBER ASSEMBLY, METHOD FOR PRODUCING CARBON NANORODS, AND METHOD FOR PRODUCING GRAPHENE NANORIBBONS
Document Type and Number:
WIPO Patent Application WO/2021/149111
Kind Code:
A1
Abstract:
A method for producing a spherical nanocarbon fiber assembly, said method comprising: a spray freezing step (S2) wherein a dispersion liquid containing cellulose nanofibers is sprayed onto brine so as to be frozen, thereby obtaining a frozen body; a drying step (S3) wherein the frozen body is dried under a vacuum, thereby obtaining a dried body; and a carbonization step (S4) wherein the dried body is heated and carbonized in an atmosphere in which the dried body is not combusted, thereby obtaining a spherical nanocarbon fiber assembly.
