摘要:本研究以鞣花酸（EA）和FeCl3·6H2O为原料，通过配位作用构建EA/Fe3+低聚体，并利用π-π堆积作用与纳米共轭碳材料（石墨烯、碳纳米管）结合，制备了水相稳定的功能性纳米共轭碳材料分散液。通过调节pH和EA质量分数，系统研究了分散液的粒径分布、Zeta电位及微观形貌，并将其应用于壳聚糖水凝胶涂层和锂电池负极材料。结果表明，EA/Fe3+低聚体通过配位作用和空间位阻效应显著改善了纳米共轭碳材料的分散性，其涂层表现出优异的导电性（1.57×10-1 S/m）和压阻响应特性，且EA/Fe3+/碳纳米管作为锂电池负极时，比容量可达26.75 F/g。
Abstract:In this study， ellagic acid (EA) and FeCl3·6H2O were used as raw materials to construct EA/Fe3+ oligomers through coordination interactions. These oligomers were combined with nano-conjuated carbon materials (graphene， carbon nanotubes) via π-π stacking interactions to prepare aqueous-phase stable functional nanocarbon material dispersions. By adjusting the pH and EA mass fraction， the particle size distribution， Zeta potential， and microstructure of the dispersions were systematically investigated， and the dispersions were applied to chitosan hydrogel coatings and lithium battery anode materials. The results showed that the EA/Fe3+ oligomers significantly improved the dispersibility of nano-conjuated carbon materials through coordination interactions and steric hindrance effects. The coatings 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 26.75 F/g.
