Description:

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

Abstract

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.
