Graphene-Based Hybrid Materials and Their Applications

Graphene-based hybrid materials have emerged as a cornerstone in the advancement of nanotechnology, owing to their exceptional properties and extensive potential for a wide range of applications. This chapter offers a thorough examination of graphene, beginning with an introduction to its distinctive structure and properties. It explores both top-down and bottom-up synthesis methodologies, including techniques such as mechanical, chemical, and plasma exfoliation, alongside chemical vapor deposition and epitaxial growth. Comprehensive coverage is given to key characterization techniques, including Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS), to elucidate the structure–property relationships of graphene. The discussion then transitions to graphene-based hybrid materials, addressing their synthesis and categorization into various types, including metal, polymer, and ceramic hybrids. The chapter further explores the applications of these materials across electronics, optoelectronics, energy storage, biomedical fields, and environmental applications. By providing an in-depth analysis of these hybrids, the chapter underscores their transformative role in advancing technologies across multiple sectors, particularly in energy conversion, biomedical innovations, and environmental sustainability.
