Summary

Paramagnetic (or spin) sensors have found wide use in structural and dynamic research of condensed media using the spectroscopy of electron paramagnetic resonance (EPR). Stable nitroxide radicals are the most exploited paramagnetic sensors which formed the basis of spin probes and labels technique well known to the experts in fields of chemical and biological materials science.

With the proliferation of new materials (composites, nano-dimensional fillers) new trends in the methodology of paramagnetic sensors application have been outlined. This book is devoted to these new trends in polymers and nanocomposites research. It observes the methods of adaptation of EPR spectroscopy of paramagnetic sensors to interface layers investigation, analysis of the systems containing magnetic nanoparticles, identification of composites ingredients by EPR spectra of free radicals, detection of the shear component of polymer materials deformation.

This book also presents, at an accessible level, the theory of EPR, the structure and properties of paramagnetic sensors - stable nitroxide radicals and methods of basic parameters calculation from their EPR spectra.

Intended for researchers and educators specialized in polymer material science and colloid chemistry. This book can also be used as a practical guide on paramagnetic resonance and paramagnetic sensors application for students and postgraduates.
