Adsorption and external stimulation of single polymer chains — •Kirsten Dammertz, Alexander Gerstmayr, Masoud Amirkhani, and Othmar Marti — Department of Experimental Physics, Ulm University

In the presented work, we study the behavior of externally stimulated single polymer chains (exposed to different vapors or electric fields) interacting with substrates like mica or graphite. Conformational changes and reorientation of adsorbed polymers are visualized by means of an advanced, custom-made atomic force microscope (AFM).

To verify our data and analyze the underlying chemical and physical processes, we perform molecular dynamics (MD) simulations. Moreover, we use Monte Carlo (MC) and density functional theory (DFT) simulation techniques to improve our analysis and to compare the experimental result with prior assumptions [1,2].
