Characterizing Carbon Materials with Raman Spectroscopy
Characterizing Carbon Materials with Raman SpectroscopyJoe Hodkiewicz, Thermo Fisher Scientific, Madison, WI, USAI ntroductionCarbon nanomaterials have revolutionized the field ofmaterial science in recent years. Individual carbonnanomaterials offer a wide range of useful propertiespertaining to electrical conductance, thermal resistance,and exceptional strength, making them very interestingmaterials to a broad range of industries. The high-level ofinterest in the processing, modification, and customizationof these Materials has created a strong demand fortechniques that can be used to characterize carbonnanomaterials. Raman Spectroscopy is one technique that has proven to be very well suited to many of thecharacterization needs with these Spectroscopy is most sensitive to highlysymmetric covalent bonds with little or no natural dipolemoment.
Graphene: Graphene is the fundamental building block of many important carbon materials including graphite. Graphite consists of stacks of sp2 bonded planar graphene sheets. When comparing Raman spectra of graphene and graphite, at first glance the spectra look very similar. This is not too surprising as graphite is just stacked graphene ...
