A comprehensive reference guide examining current challenges and opportunities in the fi eld of multicomponent polymer systems.
Multiphase polymer systems are an important research topic from both industrial and fundamental points of view. This new generation of materials offers enhanced physical, mechanical, thermal, electrical, magnetic and optical properties, and fi nds use in many fi elds such as automotive, aeronautics and space industry, cabling, civil engineering and medicine. They cover a wide range of materials such as composites, blends, alloys, gels and interpenetrating polymer networks.
This double-volume book examines the recent advances covering physical, interfacial, and thermophysical properties of multiphase polymer systems. It includes manufacturing and processing techniques, characterization techniques, materials modeling, applications and also ageing, degradation and recycling. It pays particular attention to characterization at different length scales (macro, micro and nano) which is necessary for a full understanding of the structure-property relationships of multiphase polymer systems.
Ideal for researchers in both industry and academia who wish to learn about these promising new materials, the Handbook of Multiphase Polymer Systems is also useful for plastic and rubber technologists, fi ller specialists and researchers in fi elds studying thermal, mechanical and electrical properties.

Foreword
Multiphase polymer systems have been the focus of recent research and have become an important issue fromboth the industrial and fundamental points of view. The scientific literature devoted to multiphase polymersystems is large and growing as it covers a wide range of materials such as composites, blends, alloys, gelsand Interpenetrating Polymer Networks.
During the last two decades, major opportunities have appeared due to the possibility of tuning the differentrelevant length scales with the promise to produce a new generation of materials displaying enhanced physical,mechanical, thermal, electrical, magnetic, and optical properties. In spite of these intensive investigations,there are still many unresolved problems in this field. One of the main issues is the influence of the shape, sizeand dispersion of the particles in the polymer matrix on the macroscopic behavior of the resulting material.There are many factors which control the dispersion, and one of them is the interaction between the particlesand the polymer phase. Describing the interactions between the various components, the physical attributes ofpolymers and particles, the physical, thermophysical and interfacial properties in a comprehensive universalscheme remains a challenge. This approach requires collecting a large number of experimental data that canbe obtained only by using various and complementary experimental techniques.
Investigations in this field cover different topics, such as polymer blends and composites and nanocom-posites reinforcement, barrier properties, flame resistance, electro-optical properties, etc. Part of these multi-phase polymer materials belong to the so-called smart materials which are materials that have one or moreproperties that can be significantly changed in a controlled fashion by external stimuli. The key to the suc-cess of these smart materials hinges on the ability to exploit the potential of nano-structuring in the finalproduct.
This book discusses many of the recent advances that have been made in the field of morphological,interfacial, physical, rheological and thermophysical properties of multiphase polymer systems. Its content isoriginal in the sense that it pays particular attention to the different length scales (macro, micro and nano) whichare necessary for a full understanding of the structure–property relationships of multiphase polymer systems.It gives a good survey of the manufacturing and processing techniques needed to produce these materials.A complete state-of-the-art is given of all the currently available techniques for the characterization of thesemultiphase systems over a wide range of time and space scales. Theoretical prediction of the properties ofmultiphase polymer systems is also very important, not only to analyze and optimize material performance, butalso to design new material. This book gives a critical summary of the existing major analytical and numericalapproaches dealing with material property modeling. Most of the applications of these smart materials arealso reviewed which shows clearly their important impact on a wide range of the new technologies which arecurrently used in our daily life. Finally, the ageing, degradation and recycling of multiphase polymer systemsis not forgotten and some routes are proposed to avoid environmental contamination.
The 52 contributors of this book are all leading researchers in their respective fields, and I warmlycongratulate the editors Abderrahim Boudenne, Yves Candau, Laurent Ibos and Sabu Thomas for bringingthem together to produce this original and important book dealing on multiphase polymer systems.
