The purpose of this poster was to compare and contrast the benefits of FT-IR and Raman microscopy mapping and imaging for the analysis of layered polymer composites. Here is a summary of the methods and results.
To learn more about these techniques, access our online technology learning centers.
- On our FTIR Spectrsocpy Academy pages, you can find everything FTIR, from the most basic (what do “FT” and “IR” mean?) to applications using hyphenated techniques, like TGA-IR. Along the way, you can find information on sample preparation for transmission experiments, the power of FTIR Microscopy and charts relating chemical structure to the infrared spectrum.
- For Raman spectroscopy, a form of vibrational spectroscopy (which is a proven and trusted technology that provides highly accurate results), visit our Rethinking Raman page where you can access information, applications notes, webinars and testimonials.
An important advantage of FT-IR micro-spectroscopy is that the spectra highlight polar functional groups which are particularly important when characterizing different types of polymers. A large number of FT-IR spectral data bases are available for identification of polymeric materials.
Raman micro-spectroscopy offers excellent spatial resolution as well as convenient sampling options. Raman spectroscopy tends to highlight molecular backbone structure and is sensitive to molecular structure. Raman spectroscopy provides access to a greater spectral range that is useful for analyzing a wider range of different types of materials such as pigments.
These techniques work very well together and provide complementary information, so rather than considering these as an either or proposition, a concerted approach using both FT-IR and Raman imaging would be an excellent solution for the analysis of layered polymer composites.
