The Equilibrium Theory of Inhomogeneous Polymers


Book Description

The Equilibrium Theory of Inhomogeneous Polymers provides an introduction to the field-theoretic methods and computer simulation techniques that are used in the design of structured polymeric fluids. By such methods, the principles that dictate equilibrium self-assembly in systems ranging from block and graft copolymers, to polyelectrolytes, liquid crystalline polymers, and polymer nanocomposites can be established. Building on an introductory discussion of single-polymer statistical mechanics, the book provides a detailed treatment of analytical and numerical techniques for addressing the conformational properties of polymers subjected to spatially-varying potential fields. This problem is shown to be central to the field-theoretic description of interacting polymeric fluids, and models for a number of important polymer systems are elaborated. Chapter 5 serves to unify and expound the topic of self-consistent field theory, which is a collection of analytical and numerical techniques for obtaining solutions of polymer field theory models in the mean-field approximation. The concluding Chapter 6 provides a discussion of analytical methods for going beyond the mean-field approximation and an introduction to the exciting new field of field-theoretic polymer simulations - the direct numerical simulation of polymer field theory models. No other book brings together in such a detailed and instructive fashion the theoretical and numerical tools for investigating the equilibrium structure and thermodynamics of meso-structured polymer formulations, including those relevant to soft material nanotechnologies, personal care products, and multiphase plastic materials.

Theory of Block Polymer Self-Assembly


Book Description

This primer introduces the theory of self-assembly of block polymers, most notably self-consistent field theory (SCFT). Block polymer self-assembly is a fascinating and highly interdisciplinary topic. This primer can be read at several levels, depending on what readers want to get out of it. Readers who want an overview of self-assembly in block polymer and what SCFT says about the process can read Chapters 1-3 and skip to Chapter 7 to see the open questions. If the reader is further interested in the output of SCFT calculations but not how those outputs are generated, they should read Chapter 6 as well. But if the reader wants to learn how to do the SCFT calculations themselves, Chapters 4 and 5 offer an accessible introduction to the theory and numerical methods, providing an excellent entry point into the literature. This primer includes data that the authors have computed using SCFT. All calculations use the open-source software package Polymer Self-Consistent Field (PSCF), developed by David Morse at the University of Minnesota. Take breaks from reading to watch ten “Insider Q&A” videos included throughout, which offer additional insight from experts in the field, such as An-Chang Shi, Chinedum O. Osuji, Frank S. Bates, Christopher M. Bates, Glenn H. Fredrickson, and Lisa Hall. Furthermore, this primer includes multiple features to aid and enhance readers’ learning. “That’s a Wrap” summarizes key concepts at the end of each chapter, while “Read These Next” suggests references that may interest further reading. A pop-up glossary ensures readers have definitions as needed throughout the primer.
