Graphene Powder - Material Information

Graphene powder, composed of mono- to few-layer carbon sheets, is an advanced nanomaterial exhibiting exceptional electrical, thermal, and mechanical properties. Since its isolation in 2004 by Andre Geim and Konstantin Novoselov, graphene has transformed materials science, offering ultrahigh conductivity, flexibility, and strength in a single atomic layer. Its powder form enables scalable incorporation into polymers, ceramics, and metals to enhance composite performance across electronics, energy storage, and structural applications.

Material Overview

Graphene exhibits an intrinsic electrical conductivity exceeding 10? S·m?¹ and an in-plane thermal conductivity up to 5000 W·m⁻¹·K⁻¹, outperforming most known materials. Each carbon atom in graphene is bonded via sp² hybridization, forming a two-dimensional honeycomb lattice with a high Young’s modulus (~1 TPa) and tensile strength (>100 GPa). Zych et al. (2015) demonstrated that hot-pressed graphene laminates exhibit strong anisotropy, with in-plane thermal conductivity of 360 W·m⁻¹·K⁻¹ compared to just 3 W·m⁻¹·K⁻¹ through-plane, highlighting its directional heat conduction capabilities. Furthermore, Xin et al. (2015) fabricated graphene fibers with thermal conductivities up to 1290 W·m⁻¹·K⁻¹ and tensile strengths reaching 1080 MPa, proving graphene’s potential in lightweight, high-strength materials. Recent advances (Moustafa et al., 2023) revealed that incorporating 2.5–5 vol.% graphene into aluminum composites boosts thermal conductivity by 20% and hardness by 30%, underscoring its multifunctional reinforcement potential.

Applications and Advantages

Graphene powder is integral to next-generation composite systems, conductive inks, flexible electronics, and heat-dissipating components. Its ability to enhance both electrical and thermal pathways enables high-efficiency energy storage devices, sensors, and transparent conductors. Graphene-reinforced polymers and metals exhibit reduced weight and increased fracture toughness, while maintaining environmental stability. According to Memisoglu et al. (2021), graphene-based composites enhance thermal conductivity, optical transparency, and flexibility in photonic and electromechanical systems, opening opportunities in wearable technology, aerospace, and high-performance coatings. The powder’s processability allows integration via melt blending, electrophoretic deposition, or powder metallurgy, making it adaptable for both research and industrial-scale applications.
