Abstract

Electron spectroscopic imagining (ESI) is a recently developed method which broadens the scope of electron microscopic imaging considerably. Phase separated diblockcopolymers of poly(styrene) (PS) and poly(methylphenylsiloxane) (PMPS) and their mixtures with the respective homopolymers exhibit domains which differ in elemental composition. One of the phases contains only carbon and hydrogen, the other one contains silicon and oxygen aoms in addition. This feature makes the systems a candidate to demonstrate the application of ESI to problems in polymer materal science. Effects of solvent and surface phenomena were studied in unstained thin solution cast films prior to and after annealing. Elemental maps are compared with micrographs which were exposed at an energy loss for which so called structure sensitive contrast predominates. Both methods utilize the inelastically scattered electrons for imaging.
