The aim of this work was to observe the complex structures of novel isotactic Polypropylenes (iPP) using tapping mode and pulsed force mode AFM. Therefore two different approaches in sample preparation were investigated. Thin film preparation on Silicon wavers with toluene solved Polypropylene served to explore the unstretched structure. The thin films were also prepared on stretchable carriers like PDMS for studying the stretched iPP. Second samples of isotactic Polypropylene microtome cuts were prepared by potassium permanganate etching. In that case some samples were stretched before preparation. The results of this measurements will be discussed.
