Opis

This lab manual introduces the reader to scanning force microscopy of polymers based on a practice-oriented approach. It aims to `teach' the reader to pick up the knowledge and skills necessary to obtain reliable results within the shortest possible time.

Recenzje

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)
