Applied Raman Spectroscopy, Rheology, and Integrated RheoRaman in Polymer Science (Ibrahim &Crawford, Thermo Fisher Scientific),


Applied Raman Spectroscopy, Rheology, and Integrated RheoRaman in Polymer Science

Mohammed Ibrahim, Ph.D., Nate Crawford, Ph.D.

Thermo Fisher Scientific, San Jose, CA, USA


Rheology is the study of the flow and deformation of matter, including fluids to solid-like materials (and anything in between). Rheological measurements are commonly used to examine or induce bulk physical material changes, such as melting, crystallization, gelation, and/or polymerization (to name a few). Raman spectroscopy, on the other hand, is a vibrational spectroscopic technique that complements rheology by providing insights to these processes at the molecular level, both chemically and morphologically.
In this presentation, we will begin by introducing Raman spectroscopy and its application in polymer science. Specific examples include analysis of crystallinity/amorphicity of polymers, polymer orientations, confocal analysis of multilayer polymer films and inclusions, as well as defects. Next, we will discuss the basics of rheology and how they pertain to polymer science. Then we will introduce the first commercially available integrated rheometer and Raman spectrometer (Thermo Fisher Scientific MARSXR rheoRaman system), providing examples of how this unique multimodal analytical tool can be used to directly correlate bulk physical behavior with chemical and conformational changes at the molecular level.

Mohammed Ibrahim is a Senior Raman Spectroscopy Applications Scientist with Thermo Fisher Scientific. Mohammed has a Ph.D. in Analytical Chemistry from Marquette University and prior to joining Thermo, he was a Postdoctoral Scholar at University of Washington, Seattle, and at Princeton University. He has more than 15 years of experience in Raman spectroscopy, working with wide variety of materials, including but not limited to, biological materials, polymers, nanomaterials and semiconductors.

Nate Crawford is the rheology applications specialist for Thermo Fisher Scientific in the U.S. and Canada. He has a Ph.D. in Chemical Engineering and over seven years of experience conducting rheological measurements. Nate has worked with a wide range of materials, from polymers, colloidal suspensions, biomass, food, and beyond.
