▎ 摘　　要

NOVELTY - A functional film comprises aggregated graphene nano ribbons. USE - Functional film is used for inner wall of pipeline for petroleum transport, and outer wall of boats and ships and aircraft. ADVANTAGE - The functional film has excellent water-repellant property and durability, and is manufactured economically, and reduces fluid friction and prevents explosion by static electricity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of functional film, which involves preparing polycyclic aromatic compound by bonding halogen with two or more carbon, producing polymer by polymerizing the polycyclic aromatic compound, forming the functional film by carrying out the anisotropic growth of the polymer, and aggregating graphene nano ribbons by carrying out dehydrogenation-cyclocondensation reaction of the aromatic ring in the polymer while generating the polymer.
