Synthesis and Medical Application of 3D Graphene Materials the crystal. This in effect makes the crystal a giant isotropic molecule, thereby making the diamond very hard (More et al., 2013). On the other hand, graphite with its anisotropic layered in-plane hexagonal covalent bonding and interplane Van der Waals bonding structure is a soft material. Within each of the planner layers, each carbon atom forms two single bonds and one double bond with its three nearest neighbours. This bonding repeats in-plane to form a giant molecule (graphene) sheet. The in-plane atomic bond length within graphite is 1.42 Å, which is a resonant intermediate between the single bond length of 1.5Å and the double bond length of 1.33Å. Aside from the fact that graphite has low hardness, it also has a lubricating property because the giant molecular sheets can easily slip past one another against the Van der Waals bonding. Some large-crystallite size natural graphite can be used as lubricants, but the artificially produced graphite can be very abrasive if the crystallite sizes are small and randomly oriented (Wang et al., 2021). Fullerene (C60) is a molecule composed of carbon atoms and often resembles a football. It is also known as footballene based on the shape of the molecule (More et al., 2013) . Fullerenes and nanotubes consist of graphene layers that are rolled up or folded to form a tube or ball. Their properties on a microscale are entirely different from those of their crystalline counterparts (Wang et al., 2021). Due to its special electronic structural characteristics coupled with its stable structure, it is widely used in heterogeneous carbon catalysts and solar cells (More et al., 2013). The focus of this review is to examine graphene materials and some important synthesis methods including the medical application of this unique material. METHOD The researchers used library research to describe the result. The data were obtained from various literatures, mainly relevant reports and scientific journals from sources such as Google Scholar and Scopus. The data were obtained by literature studies by collecting them through different sources of text data which were then processed to be a descriptive narrative. The data analysis used was content analysis. RESULT AND DISCUSSION Graphene: The Nano Structure of Graphite Graphene, an allotrope of elemental carbon is a one-atom-thick planner sheet of sp2-bonded sheet of carbon atoms densely packed in a 2D honeycomb crystal lattice. This material is gaining appreciable attention in recent years due to its exceptional properties such as high current density, ballistic transport, chemical inertness, high thermal conductivity, optical transmittance, and super- hydrophobicity at the nanoscale. The first graphene was extracted from graphite using the micromechanical cleavage technique, the approach allowed the production of high-quality graphene crystallites and further led to enormous experimental activities (Choi et al., 2010). Furthermore, various methodological approaches have been developed for the synthesis of graphene over the years which include exfoliation of graphite, chemical vapour deposition (CVD), thermal decomposition epitaxial growth on electrically insulated surfaces, unzipping of carbon 2522|Indonesian Journal of Multidisciplinary Science, 2(5), Feb, 2023PDF Image | Medical Application of 3D Graphene
