This open access book reviews the recent research achievements of the investigation of
interfacial phenomena in polymer polymer and polymer metal joint interfaces with the
state-of-the-art analytical techniques not previously used in the field of adhesion and
bonding. Adhesion performance is determined not only by the two-dimensional interfaces but also
by a three-dimensional (3D) region having different properties and structural characteristics
that extends into the bulk materials. In this book the authors also discuss in detail the
bonding mechanism by characterizing such 3D regions called interphase. The book is of great
interest to researchers and engineers devoted to adhesion science and technology. Videos via
