▎ 摘　　要

NOVELTY - A graphene modified polyaryl ether ketone polymer material comprises 10-15 wt.% graphene nano dispersion slurry, 25-45 wt.% polyaryletherketone polymer, 3-5 wt.% silane coupling agent, 2-5 wt.% molecular sieves and 30-60 wt.% polar solvent. USE - Graphene modified polyaryl ether ketone polymer material used in coating such as oil well pipe coating, heat exchanger coating, oil tank inner wall insulation coating and subsea pipeline coating (all claimed). ADVANTAGE - The graphene modified polyaryl ether ketone polymer material has reduced viscosity, and the coating has reduced cost, anti-cracking effect, high electrical conductivity, heat resistance, cathode stripping resistance, and self-healing function. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) use of polymer material in coating; and (2) production of polymer material, which involves preparing graphene nano dispersion slurry using graphene powder, mixing graphene nano dispersion slurry, polyaryletherketone polymer, silane coupling agent, molecular sieves and polar solvents, grinding, and dispersing.
