Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

Surface Engineering of Polymer Membranes covers the processes that modify membrane surfaces to improve their in-service performance, meaning, to confer surface properties which are different from the bulk properties. Purposes may be to minimize fouling, modulate hydrophilicity/ hydrophobicity, enhance biocompatibility, create diffusion barriers, provide functionalities, mimic biomembranes, fabricate nanostructures, etc. First, the basics of surface engineering of polymer membranes are covered. Then topics such as surface modification by graft polymerization and macromolecule immobilization, biomimetic surfaces, enzyme immobilization, molecular recognition, and nanostructured surfaces are discussed. This book provides a unique synthesis of the knowledge of the role of surface chemistry and physics in membrane science. Dr. Zhikang Xu of the Institute of Polymer Science of Zhejiang University has eight Chinese patents and in 2006 was honored as a Distinguished Young Scholar by the National Natural Science Foundation of China (NNSFC).

This book addresses plasma modification of polyolefin surfaces. It comprises 21 chapters divided into three major sections. The first section covers the different techniques used for plasma modification of polyolefin surfaces and the effects of various gases as a surrounding medium, while the second provides a detailed analysis of the physics and chemistry of plasma modification and discusses various innovative characterization techniques, as well as ageing of the modified surface. It focuses on the analysis of changes in polymers’ surface chemistry using various spectroscopic techniques, and of changes in their surface morphology after plasma treatment using optical microscopy, electron microscopy and atomic force microscopy. In addition, it provides detailed information on the characterization of modified polymer surfaces. The book’s third and last section covers a range of applications of plasma-modified polyolefin surfaces varying from the packaging industry to the biomedical field, and shares valuable insights on the lifecycle analysis of plasma modification and modified surfaces.

It is not unknown that the worldwide freshwater supply is dwindling and current freshwater sources are being contaminated. The total amount of freshwater, which makes up 2.5- 3% of the total water on earth, is actually sufficient to sustain the growing population for many years. However, the disproportionate geographical distribution of freshwater raises issues, as many people occupy arid regions. The transport or piping of large volumes of water over long distances is typically prohibitively expensive and/or prevented by geopolitical interests. The drive to produce freshwater locally from non-traditional sources has advanced in recent years and current energy and production costs have fallen due to technological advances. Filtration through polymeric materials has emerged as the leading technology for freshwater production from seawater, brackish water, and wastewater. Polymer membranes have surpassed ceramic membranes as the leading filtration medium because of their low-cost and versatility. Large sheets of membranes can be cast using an in-line manufacturing process and pore sizes can be readily tuned for specific applications. However, membrane fouling severely limits the advantages and economics of polymeric membrane-based separations. This dissertation will examine methods to produce fouling-resistant membranes that maintain the low- cost and scalability of polymer membranes for ultrafiltration and reverse osmosis. The first chapter presents a brief history and introduction to membrane technology and its current status. This chapter outlines membrane casting methods, the polymers used in casting films and their advantages, different configurations for membrane modules, the effects of fouling, and the cost of fouling. The second chapter introduces a new hydrophilic, polyaniline-based additive that was synthesized to blend into polysulfone unltrafiltration membranes. Sulfonated polyaniline (SPANi) is a self-doped polyaniline derivative that is readily synthesized using fuming sulfuric acid. SPANi, when de-doped, is soluble in polar organic solvents and insoluble in water, making it an excellent candidate for blending into ultrafiltration membranes. When redoped at pH 7, the presence of pendant sulfonic acid groups creates a zwitterionic species. Zwitterionic moeities are known to possess super-hydrophilic and ultra-low fouling properties. When blended into polysulfone (PSf) ultrafiltration membranes at low concentrations, the SPANi-PSf membranes demonstrate greater hydrophilicity and anti-fouling properties when compared to pure PSf membranes with nominal changes in performance. For reverse osmosis (RO) membranes, the active or "skin" layer that performs the separation is a dense, non-porous polymer. Thus, blending hydrophilic molecules into the active layer or modifying the chemistry of the active layer affects the separation properties of the resulting polymer blend. To address this issue, researchers have grafted hydrophilic polymers to the surface of membranes to impart anti-fouling properties without significant changes in their performance. In Chapter 3, a new method is presented using photoactive hydrophilic polymer precursors to modify membrane surfaces. With this new method, commercial RO membranes can be modified rapidly under ambient conditions, maintaining the roll-to-roll scalability of RO membrane processing. The grafted commercial RO membranes exhibit enhanced hydrophilicity and anti-fouling properties when compared with unmodified RO membranes. Chapter 4 investigates applying the same method of imparting anti-fouling properties to polymeric membranes as discussed in Chapter 3, except here this method is applied to ultrafiltration (UF) membranes used for membrane bioreactors. Membrane bioreactor technology has gained attention recently for its highly efficient ability to clean wastewater. However, the concentrated loading of organics and microorganisms into the reactor medium leads to high fouling rates. First, modeling data are presented that identifies specific acid-base interactions between different foulants and the membrane surface that accelerate membrane fouling. New photoactive small molecule precursors were then synthesized and covalently bound to the membrane surface to repel these interactions. The small molecule with the greatest repulsive interaction, a zwitterionic derivative, imparted the greatest anti-fouling properties to the commercial UF membranes. The modified membranes exhibited low fouling rates in both a short-term and a long-term study. Chapter 5 summarizes the dissertation and outlines the key takeaways.
