Graphene Applications and Development Status

Graphene is a 2-dimensional (one atom thick) structure of graphite, composed of carbon atoms tightly bonded together in a hexagonal lattice. These physical properties give graphene an extraordinary combination of high strength, low weight, high thermal and electrical conductivity.

These potential applications include:

  • Biological engineering: bioelectric sensory devices, antibiotic / anti-cancer treatment, tissue regeneration
  • Optical electronics: rollable e-paper, flexible electronic components and displays
  • Ultrafiltration: water purification, desalination, biofuel manufacturing
  • Composite materials: higher-strength, lower-weight replacement for current carbon fiber composites in aircraft and other vehicle structures, body armor
  • Photovoltaic cells: cost-effective, high-efficiency replacement for silicon solar cells in current applications, and new applications for flexible PV cells such as window screens and installations on curved surfaces.
  • Energy storage: higher-capacity supercapacitors and batteries

A key limitation to developing graphene applications has been the relatively high cost of manufacturing graphene. Presently, chemical vapor deposition (CVD) is the process commonly used to manufacture high-quality graphene on a large scale. A breakthrough in lower-cost CVD manufacturing technology recently was announced by the firm Carbon Sciences, Inc. and the University of California Santa Barbara (UCSB).
