Klappentext zu „Scanning Force Microscopy of Polymers “
Scope of the Book Synthetic and natural polymers exhibit a complex structural and morphological hierarchy on multiple length scales [1], which determines their performance. Thus, research aiming at visualizing structure and morphology using a multitude of microscopy techniques has received considerable attention since the early days of polymer science and technology. Various well-developed techniques such as optical microscopy and different forms of electron microscopy (Scanning Electron Micr- copy, SEM; Transmission Electron Microscopy, TEM; Environmental Scanning Electron Microscopy, ESEM) allow one to view polymeric structure at different levels of magni?cation. These classical techniques, and their applications to po- mers, are well documented in the literature [2, 3]. The invention of Scanning Tunneling Microscopy (STM) inspired the devel- ment of Atomic Force Microscopy (AFM) and other forms of scanning proximity microscopes in the late 1980s [4, 5]. AFM, unlike STM, can beused to image n- conducting specimens such as polymers. In addition, AFM imaging is feasible in liquids, which has several advantages. Using liquid imaging cells the forces between specimen and AFM probe are drastically reduced, thus sample damage is prevented. In addition, the use of water as imaging medium opened up new applications aiming at imaging, characterizing, and analyzing biologically important systems.
This lab manual introduces the reader to scanning force microscopy of polymers based on a practice-oriented approach. It begins with a broad introduction to the necessary background of SFM, including intermolecular forces and various SFM imaging modes. "Scanning Force Microscopy of Polymers" is developed in a didactically clear and easily understandable style. The application of SFM to visualize and study polymers is exemplified by numerous case studies, including experimental protocols. In addition, the book helps the reader to develop a conscious and critical understanding of SFM data. This approach enables the reader to acquire the knowledge and experimental skills that are necessary to understand and obtain good and reliable SFM results within the shortest time possible.

Rezension zu „Scanning Force Microscopy of Polymers “
From the reviews:"Atomic force microscopy (AFM) can be used to image polymer surfaces over a broad range from several nanometers to more than 100 micrometer scan sizes. ... one of the most engaging and practical books ever on the topic of AFMs. It provides the reader with insightful methods for imaging polymer surfaces at elevated temperatures and in other situations. ... would be suitable for both industrial researchers and academic personnel working in the laboratory. ... Anyone who uses an AFM will find this book extremely useful." (IEEE Electrical Insulation Magazine, Vol. 27 (4), July/August, 2011)
