Electron energy-loss spectroscopy is shown to provide information on the chemical state of carbon atoms in the poly(ether ether ketone) molecule, through comparison with X-ray photoelectron spectroscopy. A careful study of beam damage effects on the energy-loss spectra is presented as a function of electron dose. This ensures that the final results relate to the undamaged polymer, and permits a discussion of the limits of spatial resolution with which the energy-loss technique can be applied to phase-separated systems incorporating an aromatic polymer. The conclusion reached is that energy-loss spectroscopy can provide chemical state information for aromatic polymer systems from regions as small as 140 x 140 nm 2.
