▎ 摘　　要

NOVELTY - Sheet-layer array composite material comprises metal nanoparticle nucleation site which is supported on the graphene sheet, where a conductive polymer nanocluster array is grown on the nucleation site. The conductive polymer nanowires that grow on the ink sheet layer away from the ink sheet layer form conductive polymer nanoclusters. USE - Sheet-layer array composite material for heat absorption and conduction used in the fields of thermal conductivity sensors, drug carriers, thermosensitive devices, photothermal treatment materials, etc. ADVANTAGE - The sheet-layer array composite material has a nano-scale sheet structure with a nano-array secondary structure on the surface of the sheet. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite material, whcih involves adding graphite oxide and metal precursor salt to water, sonicating for 1-4 hours and mixing uniformly, volatilize the solvent to the solid content of the solution 0.5-20%, freeze-drying, chemically reducing to obtain a graphene material carrying metal nanoparticle nucleation sites, adding electrolyte solution containing conductive polymer precursor small molecule and shape directing agent to a buffer solution with a pH value of 2-13, coating graphene material on a carbon fiber substrate as a working electrode, polymerizing small molecules of the precursor of the conductive polymer electrochemically to the nucleation sites of the graphene material to obtain a sheet-layer array composite material.
