研究目的
To provide a general introduction about graphene nanocomposites studied by Raman spectroscopy, including descriptions of Raman bands in carbon allotropes, comparisons between different carbon nanomaterials, and investigation of graphene and graphene oxide nanocomposites.
研究成果
Raman spectroscopy is a powerful tool for investigating carbon nanomaterials, capable of detecting structural changes and distinguishing between different allotropes such as diamond, graphite, CNTs, and graphene. It is particularly useful for determining the number of graphene layers and characterizing nanocomposites.
研究不足
The chapter is a review and does not specify experimental limitations; it focuses on summarizing existing knowledge without detailing constraints or optimization areas for specific experiments.

The chapter is a review and does not describe a specific experimental design; it discusses the use of Raman spectroscopy for characterizing carbon nanomaterials.
2：Sample Selection and Data Sources:
References various studies and commercial samples such as graphene oxides from NanoInnova Technologies, graphite, SWCNTs, and MWCNTs from Aldrich.
3：List of Experimental Equipment and Materials:
Mentions a Renishaw confocal spectrometer with 473 nm laser excitation wavelength and
4：25 mW laser power, and samples like graphene oxides, graphite, SWCNTs, MWCNTs. Experimental Procedures and Operational Workflow:
Describes general procedures for Raman spectroscopy analysis, including sample preparation and measurement conditions.
5：Data Analysis Methods:
Involves analyzing Raman spectra to identify peaks (e.g., D, G, 2D bands) and their intensities to characterize materials.
