▎ 摘　　要

NOVELTY - The graphene dendrites with multiple branches of considerable aspect ratios, are claimed. The graphene dendrites are formed by starting with graphene nuclei on a solid surface extending outwardly into multiple primary branches, from which many secondary branches extend. The graphene dendrites are built based on graphene nuclei extending outwardly from each nucleus in multiple directions to form many branches on a crystalline structure of the substrate. The main branches have length-to-width ratios (aspect ratios) that increase with the length of the growth time period. USE - The graphene dendrites are useful for forming graphene plates (claimed) that are useful in photonic and electronic parts, fuel cells, electrochemical products, sensory devices, field emission, hydrogen storage and other power-supplying materials. ADVANTAGE - The graphene dendrites have high aspect ratios in their branches, and can be simply produced with high quality. DETAILED DESCRIPTION - The graphene dendrites with multiple branches of considerable aspect ratios, are claimed. The graphene dendrites are formed by starting with graphene nuclei on a solid surface extending outwardly into multiple primary branches, from which many secondary branches extend. The graphene dendrites are built based on graphene nuclei extending outwardly from each nucleus in multiple directions to form many branches on a crystalline structure of the substrate. The main branches have length-to-width ratios (aspect ratios) that increase with the length of the growth time period and reach values exceeding the aspect ratio of 100. The graphene branches are heteroepitaxially grown on a crystalline structure of the substrate. The six main branches extend from a graphene nucleus outwardly with nearly six-fold symmetry similar to a snowflake of six-fold symmetry. A morphology of graphene varies with the shapes of graphene nuclei, and exhibits four, five or six main branches depending on the crystalline structure at nucleation sites on a surface of the substrate. The branches are single crystalline, and monolayer graphene. An INDEPENDENT CLAIM is included for a method for nucleating and growing graphene dendrites with multiple branches of considerable aspect ratios.
