The unique profile of graphene nanomaterials enables transformative impact across multiple sectors.
: Used in high-performance lithium-ion batteries and supercapacitors to achieve faster charging and higher energy densities.
: Uses electrolytes and electrical current to intercalate and peel graphene layers, offering a balance of quality and quantity. Bottom-Up Methods These techniques build graphene from molecular precursors.
Graphene Nanomaterials: Fabrication, Properties, and Emerging Applications
: The "Scotch tape" method used to first isolate graphene. While it produces high-quality flakes, it is not scalable for industrial use.
Graphene, a single-atom-thick sheet of carbon arranged in a hexagonal honeycomb lattice, is a pioneering two-dimensional (2D) nanomaterial. Since its groundbreaking isolation in 2004, it has attracted immense scientific and industrial attention due to its record-breaking mechanical, electrical, and thermal performances. Fabrication Strategies
Approximately 100 times stronger than steel with a Young's modulus of ~1.0 TPa. High electron mobility (up to 200,000 ), making it a zero-bandgap semiconductor. Thermal Conductivity Extremely high values reaching ~5000 , superior to copper and diamond. Optical Transparency
