Applications: 

• Composite Reinforcement: Amino functional groups and high surface reactivity promote strong interfacial bonding with polymer, elastomer, and metal matrices; improves mechanical strength and electrical/thermal conductivity.
• Surface Modification and Adhesion Promotion: TEPA amines enable covalent or strong ionic interactions with substrates, enhancing adhesion in coatings, adhesives, and resin systems.
• Dispersion Stabilization: Amine functionality improves compatibility and stability in aqueous and many organic solvents and polymer solutions; yields homogeneous distribution in films and inks.
• Sensors and Bio‑immobilization: Surface amines provide active sites for conjugation of biomolecules or chemical receptors; useful for gas, chemical, and biosensor functionalization.
• Electrode and Energy‑Storage Modification: Incorporation of amine‑functional rGO into electrodes can enhance electrochemical stability, capacitance, and charge transport.
• Coatings and Corrosion Protection: Functional rGO layers improve barrier properties and substrate binding, contributing to corrosion resistance on metal surfaces.
• Catalysis and Catalyst Supports: Surface amine ligands facilitate immobilization and stabilization of metal nanoparticles; suitable for heterogeneous catalysis applications.
• Thermal Management in Composites: Improves interfacial heat transfer and overall thermal conductivity for TIMs, heat spreaders, and thermal management solutions.
• Membranes and Separation (Functional Modification): Amine functionality enables selective interactions and tuning of hydrophilicity/hydrophobicity, enhancing filtration and separation performance.
