ABSTRACT

The novel concept in the area of composite materials reveals sound features inside the materials. Specifically, unexplored chalcogenide – graphene glassy composite materials could be one of the potential fields for this innovation. Therefore, this chapter emphasizes newly invented chalcogenide-graphene glassy composite systems based on their experimental as well as theoretical conceptual interpretations by providing the introduction of chalcogenide alloys structural properties as well as their composite formation ability with different components. Similarly, the basic properties of graphene are also discussed in terms of their composite formation abilities with various forms of the materials, such as graphene membranes, graphene energy, graphene sensors, graphene thermoacoustics, graphene magnets, graphene superconductors and graphene in biomedicine. The fullerene like structural similarities of chalcogenides and graphene are useful for composite formation, a description is provided separately . The different kinds of chalcogenide-graphene systems such as nanocrystalline chalcogenides-graphene composites, polycrystalline chalcogenidesgraphene composites and amorphous chalcogenidesgraphene composites are also discussed. Moreover, the study is extended to the chalcogenide – graphene glassy composites and the chalcogenide composites with the single layer as well as bilayer layers graphene systems under the glassy system. This work is more towards the potential chalcogenide – bilayer layers/ or few layers graphene glassy systems and interprets the innovative research work in this area. For example, composites formations, structural modifications, modifications in surface morphologies, modifications in Raman spectrums and alternation in optical properties like UV/Visible optical property, PL property, FTIR transmission. Additionally, a brief overview on unexplored topic mechanical and electrical properties of such systems are also included. However, the thermal properties of the chalcogenide-graphene composite materials are discussed by describing their crystallization kinetics parameters, like glass forming ability, crystallization activations energies and thermal stability. The outcome of these innovative novel research works has established the new field of research area i.e., chalcogenide –graphene composites under the glassy system with their outstanding IR transparency enhancement as well as room temperature photoluminescence (PL) property for a few compositions. Moreover, experimentally contradictory results from theoretical concepts of thermal properties in these composite materials have also been addressed.
