Hydrotalcite scanning electron micrograph

Laboratory experiments of longer duration confirmed the model prediction. Figure 5 is made of scanning electron micrographs showing the surface condition after 10, 30, 120, and 600 days at 50 °C. The crystals gradually become covered by a deposit and are entirely masked after 600 days. Transmission electron microscope examination of an ultramicrotome cross-section of the layer formed after 600 days shows (1) exfoliation of the outer hydrotalcite...

Synthetic hydrotalcites employed in plastics applications are finely divided, free-flotving, odorless, amorphous powders. For polyolefin applications, hydrotalcites with an average particle size of 0.5 (tm and a specific surface area ofless than 20 m /g (BETmethod) are recommended. Their density varies around 2.1 g/cm depending on the composition. Sodium, zinc, and calcium stearate-coated hydrotalcites are available, which show enhanced compatibility with polyolefins [13]. Figure 20.3 is a scanning electron micrograph of a typical submicron-size synthetic hydrotalcite [20].
