  Amine-Enriched Reduced Graphene Oxide (TEPA-rGO Hybrid Powder) is a chemically modified graphene-based nanomaterial designed to deliver enhanced surface activity, improved dispersibility, and strong interfacial interaction capabilities. The incorporation of multi-amine functional groups onto reduced graphene oxide sheets introduces highly reactive sites that enable effective chemical bonding with a wide range of matrices and substrates.

  This functionalization strategy significantly improves compatibility in both aqueous and organic systems while preserving the intrinsic advantages of reduced graphene oxide, such as high surface area, electrical conductivity, and mechanical robustness. The presence of amine groups not only enhances dispersion stability but also allows tailored surface chemistry for advanced material design, making this product highly suitable for multifunctional composites, coatings, and electrochemical systems.
