The behaviour of polymer and plastic surfaces is critical to a variety of applications of these materials, for example in printing, adhesive bonding, lamination and biomedical applications. This in turn is governed by the chemical structure and composition of the outermost molecular layers. This book describes the instrumentation, physical bases and application of two of the most powerful techniques for polymer surface chemical analysis to have emerged in the past 25 years. It brings together the present state of knowledge in one book for the first time and is written by a pioneer in the field whose research has been driven by industrial requirements.
