AFM as a Tool for Observation and Nanomanipulation — •Alexander Schmatulla¹, Dieter Meinhard², Bernhard Rieger², and Othmar Marti¹ — ¹Department of Experimental Physics, University of Ulm, 89069 Ulm, Germany — ²Department of Anorganic Chemistry II , University of Ulm, 89069 Ulm, Germany

We show the possibility of a custom built Atomic Force Microscope (AFM) as an useful tool for observation and nanomanipulation in material science. In particular we have analysed spin coated polymer networks. First we demonstrate an appropriate preparation of the polymer sample. Using the AFM, particular polymer strains have been pulled over several well defined distances. Further we will compare our results with SEM images, GPC results and other methods. Finally the corresponding changes on the sample will be discussed.
