"Chemical Imaging by Raman and Luminescence Spectroscopies for the
Characterization of Polymer and Polymer Blend Structure"

David Tuschel, ChemImage Corp.


Full field-of-view hyperspectral imaging by Raman and luminescence modalities have been developed and applied for the characterization of crystallinity, density and defects in bulk, extruded and coated
polymers. In addition, polymer blends can be imaged for characterization of degree of mixing, orientation and chemical interaction. We will review some aspects of the physical chemistry that forms the underlying basis of the chemical and physical characterization of polymers by vibrational spectroscopy. Results of
hyperspectral imaging studies of polymers and polymer blends will be presented and discussed with particular emphasis on the spatial heterogeneity revealed by full field-of-view imaging. Work performed
on blends of polyethylene terephthalate and polyethylene napthalate will be emphasized.

About the Speaker:

David Tuschel is the Principal Materials Scientist at ChemImage. He is the inventor of a commercially available hyperspectral (Raman, luminescence and visible absorption) imaging instrument incorporating
oblique illumination independent of the image capture optics. His research responsibilities at ChemImage include the development of spectral imaging applications for a wide variety of materials including, pharmaceuticals, polymers and semiconductors. David received his M.S. from the Univ. of Arizona under the direction of Prof. Jeanne E. Pemberton.

David has been awarded one patent and has published 23 research papers in refereed scientific journals and conference proceedings. He is a frequent contributor of research papers at conferences and university
lecture series, and has been an editor of the Asian Journal of Spectroscopy since 1997.
