Abstract

This short review attempts to rediscover an « old » surface sensitive electron spectroscopic technique, namely ELS (or EELS, for Electron Energy Loss Spectroscopy); when applied to study polymers and related advanced materials, it allows to characterize the material energy gap and its electronic transitions. Four sample cases are presented: the measurement of electron induced radiation damage in polyethylene, the study of the energy gap of C60, the evidence of copper metal diffusion in poly(phenylquinoxaline) during annealing, and a preliminary study of the electronic excitations in a catenane, a macrocyclescontaining molecule.
