Abstract:

This review introduces some of the pioneering works on radiolysis of polytetrafluoroethylene (PTFE), which started in the mid 1950s. The electron spin resonance (ESR) studies on radiation-induced radicals and their corresponding peroxy radicals in PTFE were reviewed, with respect to experimental conditions, irradiation dose, structures of PTFE powders (i.e., crystallinity and crosslinking).

Key words: ESR, PTFE, irradiation, degradation, crosslinking
