국문 초록
Graphite is a material condensed from aromatic hydrocarbon that forms an infinite plane
that exhibits an amphoteric feature. Structurally, a number of benzene rings form a solid planar
sheet. A number of layers are formed from numerous unit cells, a so-called grapheme. A
graphene sheet has an electron structure, which expands π-electrons into a two dimensional
space. Graphite has AB-stacked bilayers of graphene. Because the interaction between two
sheets is weak, their electronic structure may vary significantly. In addition, because graphite
has either zero-semiconductor electronic structures, or a semi-metal electronic structure, its
ionization energy is 4 eV [1] and it has dual electronic characteristics. Thus, it may work
as either an oxidizer or reducer. In particular, the shape of the graphite plays an important
role in its mechanical characterization [2]. Graphene, in its role as a unit cell of graphite, is
known to have great potential for applications in many fields [3]. It is critical to understand
graphite’s interfacial interaction with a matrix, or its wettability, when applying its electrically
and thermally conductive properties to characteristic composites.
