Effectively Analyzing Polymers Using Electron Paramagnetic Resonance (EPR) Spectroscopy
In this webinar, Dr Kalina Ranguelova from Bruker BioSpin, will provide an overview of various industrial and academic applications and literature examples using electron paramagnetic resonance (EPR) spectroscopy to understand paramagnetic behavior of different polymer materials. The ubiquity of free radicals, triplet states, and point defects in polymer materials has rendered EPR an indispensable tool in polymer science among other mainstream analytical techniques. EPR is the best technique for shedding light on these reactions and processes because of its unique ability to unambiguously detect paramagnetic species in a direct and non-intrusive manner. The technique identifies radical reaction intermediates as well as quantifies their concentrations, thus elucidating thermal and light activated mechanisms and kinetics of polymer reactions. It can be applied to samples in liquid or sold states over a wide range of temperatures.
