▎ 摘　　要

NOVELTY - A graphene oxide reinforced coumarin based polyamide nanocomposite material comprises (c) polymeric matrix in which polymer is polyamide; and (d) graphene oxide which is graphite nanofillers dispersed in polymer matrix. USE - A graphene oxide reinforced coumarin based polyamide nanocomposite material used in aerospace aviation, construction, chemical, oil, electricity, metallurgy, shipbuilding, textile, storage, transportation, aerospace, sports and other industries in the particles. ADVANTAGE - Dispersion of graphene oxide in polyamide nanocomposites is excellent. The graphene polyimide nanocomposites have excellent mechanical properties, wear resistance and high temperature performance, low coefficient of friction and wear rate, and resistance to erosion corrosion resistant areas of coal, dust, fumes and liquids. DETAILED DESCRIPTION - A graphene oxide reinforced coumarin based polyamide nanocomposite material of formula (I) comprises (c) polymeric matrix in which polymer is polyamide of formula (Polyamide 3(a-e)); and (d) graphene oxide of formula (II) which is graphite nanofillers dispersed in polymer matrix. Ar'=aromatic diamine 2(a-e).
