Abstract: The present disclosure relates to a method for storage or transportation of graphene oxide. The method for storage or transportation of graphene oxide comprises the steps of: carrying out wet spinning of a graphene oxide spinning solution to a coagulating bath to obtain graphene oxide pellets; drying the obtained graphene oxide pellets; storing or transporting the dried graphene oxide pellets; and redispersing the stored or transported graphene oxide pellets.
