▎ 摘　　要

NOVELTY - A three-dimensional graphene tube has diameter of 10 nm-5 mm, length of 50 nm-5 mm, and contains 1-100 layers. USE - Three-dimensional graphene tube for use in solar cell, energy storage battery and conductive composite material. ADVANTAGE - The three-dimensional graphene tube has high conductivity, excellent corrosion resistance, and is manufactured economically by a simple and easily controllable process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the three-dimensional graphene tube, which involves using metal line or wire as catalyst template, directly growing graphene on outer surface of catalyst template by chemical vapor deposition method, to form graphene/metal line or wire composite structure, and removing the metal line or wire by etching.
