▎ 摘　　要

NOVELTY - Manufacture of high quality graphene involves filling carbon rod, graphite powder and metal catalyst, filling buffer gas into the reaction chamber, and evaporating carbon positioned in the positive electrode by applying the high-current between the positive electrode and negative electrode in the reaction chamber. USE - Manufacture of high quality graphene used for high quality graphene film and electronic material (all claimed). ADVANTAGE - The high quality graphene is efficiently manufactured with improved conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) high quality graphene; (2) high quality graphene film; and (3) electronic material.
