Abstract
Chapter 2. Graphite Oxide sheets have been used to prepare a strong paper-like material, and have recently attracted substantial interest as a possible intermediate for the manufacture of Graphene. Change electrical conductivity by other atoms attached to the surface of Graphene can be applied to a sensor that detects changes in the environment The case of the Silicon Quantum Dots, semiconductor particles, the Electronic space on the wall by the formation of discrete, and the size of the space gets smaller. The higher the energy state of the electrons have a broad band energy phenomena. Activated Microwave-Exfoliated Graphite Oxide (MEGO) was prepared and used for the composite materials were characterized by TEM and FE-SEM. A specific surface area was measured by the Brunauer-Emmett-Teller (BET) method. Detailed information for the composite materials will be discussed.
