Abstract：In this study，ellagic acid （EA） and FeCl3 6H2O were used as raw materials to construct EA/Fe μ33+ oligomers through coordination interactions.Theseoligomers werecombined with nano-conjuated carbon materials（（graphene，carbon nanotubes）via- π stacking interactionstoprepareaqueous-phasestablefunctionalnanocarbonmaterialdispersions.ByadjustingthepHandEAmassfractiothe particlesizedistrbutioZetapotetialdicostctureofispesiosestematicallvestigatedndtispsioe appliedtochitosanhydrogelcoatingsandlithiumbateryanodematerials.TheresultsshowedthattheEA/Feoligomerssignificantly improvedthedispersibiltofnanconjuatedcarbnmaterialsthoughcordinationinteractionsndsterichndrancefectsThecoatings exhibited excellent electrical conductivity （1. 57×10-1 S/m） and piezoresistive response characteristics.When EA/Fe³/carbon nanotubes were used as lithium battery anodes，the specific capacitance could reach 26.75F/g
