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. The Carbon - Carbon bonds that make up thesematerials fit this criterion perfectly and as a result Ramanspectroscopy is highly sensitive to these Materials and ableto provide a wealth of information about their structure.
Carbon Nanomaterials Defined There are a wide variety of different carbon nanostructures, however they all have a few basic things in common. First, all of these materials are predominantly made up of pure carbon, and as such can be called carbon allotropes. The range of these materials starts with the well known
