Graphene is a two-dimensional carbon allotrope renowned for its exceptional electrical, thermal, and mechanical properties. Composed of a single layer of carbon atoms arranged in a hexagonal lattice, graphene has revolutionized materials science through its unique combination of strength, flexibility, and conductivity. Its discovery marked a major milestone in nanotechnology, opening pathways to transformative applications across electronics, energy storage, and biomedical engineering.
Material Overview
Graphene’s sp2-hybridized carbon structure confers remarkable characteristics—mechanical strength exceeding 130 GPa, a Young’s modulus of about 1 TPa, and electron mobility surpassing 15,000 cm2·V−1·s−1 (Khan et al., 2017). Its thermal conductivity exceeds 5000 W·m−1·K−1, enabling effective heat dissipation in microelectronic devices. Graphene’s atomic thickness allows superior flexibility and transparency, transmitting up to 97.7 % of incident light (Sang et al., 2019). Owing to its high specific surface area (~2630 m2·g−1), it serves as an excellent substrate for catalysis and energy storage. Advances in chemical vapor deposition (CVD) and mechanical exfoliation have enabled scalable production of defect-minimized graphene with controlled layer thickness (Makwana & Patel, 2022).
Applications and Advantages
Graphene is utilized in flexible electronics, high-speed transistors, transparent conductive films, batteries, and composite materials. Its superior carrier mobility and low noise levels make it ideal for next-generation electronic sensors, while its mechanical strength and chemical inertness enhance the durability of polymer composites. In energy systems, graphene electrodes improve charge transfer and reduce resistance in supercapacitors and lithium-ion batteries (Etri, 2023). Biomedical applications include biosensing, drug delivery, and tissue scaffolding, where graphene’s biocompatibility and tunable surface chemistry provide unique benefits. Furthermore, in microelectromechanical systems (MEMS), graphene membranes act as ultra-sensitive resonators and pressure sensors, exploiting its electromechanical coupling and high strain tolerance (Khan et al., 2017).
