Recent progress in electron paramagnetic resonance study of polymers


The review article provides an overview of the contemporary research based on a tailor-made technique for polymers of different classes. The ubiquity of free radicals, including biradicals, triplet states, and point defects in polymer systems has rendered EPR spectroscopy an indispensible tool in polymer science among other mainstream analytical techniques. The scope of EPR spectroscopy has broadened particularly due to the growing impulse to produce polymers with enhanced stability, to follow the charge transfer process in conducting polymers, to decipher the complex nanoscale dynamics of polymers, to fathom out reaction mechanisms and kinetics of complex polymer reactions in a more facile way, and to carry out comprehensive structural and conformational analyses. Recent studies have hinted at the effectiveness of EPR spectroscopy in collecting data with sub-nanometer spatial resolution to decipher intrinsic intricacies, while keeping the pristine geometry unperturbed, a task yet not achievable with other conventional techniques. EPR spectroscopy is being applied to polymer science in multifarious ways, including, but not limited to, exploring structure, conformation, and dynamics of polymer chain segments, degradation or defect studies, charge transfer properties, kinetics and reaction mechanisms especially of free radical polymerization reactions, and EPR imaging of polymer matrix. A surge in its recent applications indicates that EPR spectroscopy is going to have a profound influence in polymer science in upcoming years.
