| Popis: |
The spherulitic and lamellar morphologies of melt crystallized isotactic polypropylene (iPP) have been investigated according to various crystallization temperatures and times. In this study, an appropriate chemical etching condition for the observation of iPP morphology by scanning electron microscopy (SEM) is determined. The optimum etchant formulation is 3 wt% potassium permanganate with the mixed solvent of sulfuric acid and phosphoric acid. The morphologies after etching reveal the microstructure of iPP clearly, such as the characterization of α/β spherulites and the different lamellar growth patterns. |
