Morphological characterization of bulk polymer blends
or compatibilized alloys at submicron spatial resolution
has almost exclusively relied upon electron microscopy
techniques. Since, however, most organic polymers are
composed of carbon and light elements, an arsenal of
methods to enhance phase contrast has been developed
to facilitate discrimination and analysis of property-
governing morphological features.1 For transmission
