This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). This project addresses fundamental questions concerning the behavior of polymers at interfaces: (1) What processes control the formation of an adsorbed layer on a clean surface? (2) What processes control the displacement of preadsorbed polymers? (3) Can one accurately predict the structure of polymer layers? To answer these questions, using neutron reflectivity, we have studied adsorbed layers of the polymer poly(methyl methacrylate) (PMMA) onto a quartz substrate. The polymer density profiles were derived from the neutron reflectivity data. We have shown that dry films exhibit behavior predicted by mean-field theory in that the equilibrated layer thickness scales with the molecular weight of the polymer. Also, we find that the profiles of the polymers in solution qualitatively agree with those predicted by reflected random walk (RRW) theories, yet the profiles are not in quantitative agreement.

This text deals with the behavior of polymers at surfaces and interfaces. Topics covered include the nature and properties of the surface of a polymer melt, the structure of interfaces among different polymers and between polymers and nonpolymers, the molecular basis of adhesion and the properties of polymers at liquid surfaces. Emphasis is placed on the underlying physical principles. It introduces statistical mechanics models of polymer behavior near interfaces, emphasizing theory that is applicable to experimental situations. Advanced undergraduates, graduate students and research workers in physics, chemistry and materials science with an interest in polymers will find this book of interest.

Physics of Polymer Surfaces and Interfaces emphasizes current theoretical ideas and modern experimental tools for characterizing the physical properties of polymer surfaces and interfaces. Foremost are their important roles in polymer technology throughthe processes of wetting, adhesion, adsorption, and through their effect on the kinetics of phase separation and mechanical mixing of molten polymers. Each of the 14 chapters in this book stands as a 'mini-review' of a specific subject. This up-to-date compendium of the most significant theoretical and experimental works provides a scientific understanding of the physics of polymer interfaces and surfaces and will aid scientists in planning and interpreting new results.

This book is concerned with the configuration of polymers at the interfacial zone between two other phases or immiscible components. In recent years, developments in technology combined with increased attention from specialists in a wide range of fields have resulted in a considerable increase in our understanding of the behavior of polymers at interfaces. Inevitably these advances have generated a wealth of literature and although there have been numerous reviews, a critical treatment with adequate descriptions of both theory and experiment, including detailed analysis of the two, has been missing. This text hopes to fill this gap, providing a timely and comprehensive account of the field as it stands today. This long needed work will be invaluable to experts as well as newcomers in the broad field of polymers, interfaces and colloids, both in industry and academia. Whilst industrial laboratories involved in this field will find it indispensable, it will be equally important to anyone with an interest in interfacial polymer or colloidal research.

This edited volume brings together the state of the art in polymer nanocomposite theory and modeling, creating a roadmap for scientists and engineers seeking to design new advanced materials. The book opens with a review of molecular and mesoscale models predicting equilibrium and non-equilibrium nanoscale structure of hybrid materials as a function of composition and, especially, filler types. Subsequent chapters cover the methods and analyses used for describing the dynamics of nanocomposites and their mechanical and physical properties. Dedicated chapters present best practices for predicting materials properties of practical interest, including thermal and electrical conductivity, optical properties, barrier properties, and flammability. Each chapter is written by leading academic and industrial scientists working in each respective sub-field. The overview of modeling methodology combined with detailed examples of property predictions for specific systems will make this book useful for academic and industrial practitioners alike.
