This Springer Laboratory volume is a practical guide for scientists and students dealing with the measurement of mechanical properties of polymers at the nanoscale through AFM force-distance curves.
In the first part of the book the reader will find a theoretical introduction about atomic force microscopy, focused on force-distance curves, and mechanical properties of polymers. The discussion of several practical issues concerning the acquisition and the interpretation of force-distance curves will help scientists starting to employ this technique.
The second part of the book deals with the practical measurement of mechanical properties of polymers by means of AFM force-distance curves. Several "hands-on" examples are illustrated in a very detailed manner, with particular attention to the sample preparation, data analysis, and typical artefacts. This section gives a complete overview about the qualitative characterization and quantitative determination of the mechanical properties of homogeneous polymer samples, polymer brushes, polymer thin films, confined polymer samples, model blends and microstructured polymer blends through AFM force-distance curves.
The book also introduces to new approaches and measurement techniques, like creep compliance and force modulation measurements, pointing out approximations, limitations and issues requiring further confirmation.

  Brunero Cappella

Brunero Cappella, born 1970 in Italy, studied physics in the University of Pisa. In 1999 he moved to Berlin, where he worked in the Federal Institute for Materials Testing and Research. He received his PhD in materials science in 2002 from the Technical University of Berlin and his habilitation in Physical Chemistry in 2008 at the University of Siegen. Currently, he is working in the Federal Institute for Materials Testing and Research, leading the group "Contact mechanics", and he is a lecturer for Physical Chemistry at the University of Siegen.
Since the very beginning of his scientific career, Brunero Cappella has been studying surface physics, atomic force microscopy and in particular AFM force-distance curves. He has written several papers; two recent review articles about force-distance curves for Surface Science Reports are among the most cited works of the journal (664 citations for the first and 1189 citations for the second article).
