Graphite, Graphene & their polymer nano composites

Graphene-based nanocomposite materials are single-or few-layer platelets that can be manufactured in bulk quantities by chemical methods. They also study the rheological, electrical, mechanical, and thermal and barrier properties of these composites and how each composite is composed of a number of routes used to manufacture graphene-based materials are examined, along with methods for dispersing these materials in different polymer matrices. Graphite or black lead, has a layered structure that consists of six carbon atoms arranged in widely spaced horizontal sheets. Thus Graphite crystallizes within the hexagonal system, in contrast to the identical element crystallizing within the octahedral or tetrahedral system as diamond. Graphite occurs as isolated scales, large masses, or veins in older crystalline rocks, gneiss, schist, quartize, marble, granites, pegmatites, and carbonaceous clay slates. Small isometric carbon crystals found in meteoritic iron are called cliftonites.
