Nanotomography of Semicrystalline Elastomeric Polypropylene — •Mechthild Döring, Nicolaus Rehse, Christian Dietz, Sabine Scherdel, and Robert Magerle — Chemische Physik, TU Chemnitz, D-09107 Chemnitz

Semicrystalline polymers contain nanometersized crystallites embedded in a matrix of amorphous material. The form and the arrangement of the crystallites determine the properties of the materials considerably. We use Nanotomography to image the three-dimensional structure of semicrystalline elastomeric polypropylene. The method is based on scanning probe microscopy imaging and subsequent etching of the sample surface layer by layer. Our aim is to automate the method as far as possible, to analyse different polymers, and to study the relations between structure and properties of the materials. Furthermore, the spatially complex structures are quantitative characterized with modern image analysis techniques.
