Synthesis and Characterization Methods of Two-Dimensional Nanomaterials

The family of two-dimensional (2D) nanomaterials is a revolutionary material with unprecedented structural, mechanical, electronic, and thermal properties. This article systematically reviews synthesis techniques and characterization methods of 2D nanomaterials such as graphene and its derivatives. Advanced synthesis routes that include chemical vapor deposition (CVD), liquid-phase exfoliation, and bottom-up approaches are critically compared to expound the impact on material quality and scalability. Furthermore, various characterization techniques such as atomic force microscopy (AFM), Raman spectroscopy, and transmission electron microscopy (TEM) are discussed to explore the structure-property relationship of nanomaterials. Major challenges include scalable production, material integration, and environmental sustainability that provide directions to future research and development.
