Modern semi-crystalline polymers based on olefin chemistry are receiving a lot of attention due to their low cost of manufacture and the ability to tailor properties by controlling polymer morphology. A common technique to visualize polymer morphology is transmission electron microscopy (TEM), with the use of appropriate contrast-enhancing heavy metal stains. One of the difficulties in obtaining a TEM image is the need to prepare an ultra-thin section. Alternative approaches that do not rely on sectioning, such as AFM and SEM imaging of a prepared block face, have shown some promise for gross morphology characterization (μm-scale) but in most cases lacked the detail that can be observed by TEM.
