Functionalized Polysulfones: Synthesis, Characterization, and Applications focuses on polysulfones and their derivatives, which are widely used as functional materials in the biochemical, industrial, and medical fields due to their structural and physical characteristics, such as good optical properties, high thermal and chemical stability, mechanical strength, resistance to extreme pH values, and low creep. Because of their antimicrobial actions, solubility characteristics, water permeability, and separation, the functional groups, which modify the hydrophilicity of polysulfones, are of particular interest for biomedical applications. In addition, the functional groups are an intrinsic requirement for affinity, ion exchange, and other special membranes. In this book, the bioapplications of polysulfones are presented in two categories: blood-contacting devices (e.g., membranes for hemodialysis, hemodiafiltration, and hemofiltration) and cell- or tissue-contacting devices (e.g., bioreactors made by hollow-fiber membrane and nerve generation through polysulfone semipermeable hollow membrane). Surface wettability and hydrophilicity trends, as well as the morphological characteristics of modified polysulfones, are analyzed for semipermeable membrane purposes. Select chapters provide an introduction to chelating units on the modified polysulfone structure to obtain potential applications, such as surface coatings on metals and glasses, adhesives, high-temperature lubricants, electrical insulators, semiconductors, and the reduction of heavy-metal pollution in ecosystems. Featuring recent scientific information, Functionalized Polysulfones: Synthesis, Characterization, and Applications advances the basic knowledge of students and researchers working in the field of polymeric materials, including physicists, chemists, engineers, bioengineers, and biologists.

Phase morphology in multicomponent polymer-based systems represents the main physical characteristic that allows for control of the material design and implicitly the development of new plastics. Emphasizing properties of these promising new materials in both solution and solid phase, this book describes the preparation, processing, properties, and practical implications of advanced multiphase systems from macro to nanoscales. It covers a wide range of systems including copolymers, polymer blends, polymer composites, gels, interpenetrating polymers, and layered polymer/metal structures, describing aspects of polymer science, engineering, and technology. The book analyzes experimental and theoretical aspects regarding the thermal and electrical transport phenomena and magnetic properties of crucial importance in advanced technologies. It reviews the most recent advances concerning morphological, rheological, interfacial, physical, fire-resistant, thermophysical, and biomedical properties of multiphase polymer systems. Concomitantly the book deals with basic investigation techniques that are sensitive in elucidating the features of each phase. It also discusses the latest research trends that offer new solutions for advanced bio- and nanotechnologies. Introduces an overview of recent studies in the area of multiphase polymer systems, their micro- and nanostructural evolutions in advanced technologies, and provides future outlooks, new challenges and opportunities.
