Electron Paramagnetic Resonance in Investigation of Polymer Fibres. A Review

  • Published:
Fibre Chemistry Aims and scope

Abstract

The results obtained with EPR in studying polymer fibres suggest the following conclusions: EPR offers broad opportunities for studying the causes of the decrease in the strength of polymer fibres on exposure to temperature and light, and stabilization of the strength properties in γ irradiation (sterilization) of medical fibre materials allows tracing the causes of the decrease in or preservation of the therapeutic properties of native and immobilized enzymes; EPR with stable nitroxyl radicals (spin-probe method) allows investigating the kinetics of formation of new phases in polymer—solvent systems and the effect of the conditions of fabricating the fibres on the quantitative ratio between dense and loose packing of macromolecules in the amorphous structure of polymers; EPR allows identifying complexation of some metal ions with different functional groups in polymers.
