Activated carbon materials are traditional chemical adsorbents because of their very high specific surface area and high micropore volume. Recently, a great deal of industrial attention has been drawn to activated carbon fiber and textiles. Textile materials in the form of fibers, yarns, and fabrics can be converted into active carbon products by the process of pyrolysis and activation. Therefore, activated carbon fiber materials have great potential for new industrial end uses, from personal protective equipment to energy storage and healthcare devices.

Using fibers and fabrics as raw materials for making activated carbon products exhibits tremendous advantages. First, activated carbon fiber has a significantly different microporous structure that allows much more rapid dynamic adsorption and desorption with less material. Second, a range of polymers can be used as precursors for making activated carbon products, including celluloses, thermosets, and thermoplastics. Finally, fiber assemblies can have diverse structures such as wovens, knits, and nonwovens. These material formats are easy to integrate into composite structures and allow easy material handling and transportation in manufacturing.

However, the technologies for fabricating, characterizing, and analyzing activated carbon fiber and fabrics are usually not included in traditional textile textbooks, because the production of activated carbon fiber and textiles is a cutting-edge technology overlapped by fiber/textile manufacturing and polymer thermochemical processes. Professionals working in this industry need to have a broader scope of knowledge that is beyond the single traditional textile discipline. This motivated me to edit a book that could address this emergent technical area. My proposal for this book, titled Activated Carbon Fiber and Textiles, was immediately supported by Sarah Lynch, Acquisitions Editor for Elsevier Woodhead Publishing.

The purpose of this book is to provide readers with the latest research progress and state-of-the-art technologies developed in the manufacture and application of activated carbon fiber and textiles. The book is divided into three sections. Section A lays the fundamentals of carbonized and activated carbon materials. The basic contents covered in this section include an overview and technical concepts of activated carbon fiber in comparison with granular activated carbon; precursor materials of activated carbon fiber; precursor fiber spinning; and the thermochemical process of activated carbon fiber. Section B covers the properties of activated carbon fibers, including their adsorptive properties, mechanical properties, electrical and thermal properties, and acoustical properties. Section C introduces the major applications of activated carbon fiber in filtration, environmental protection, power storage, and gas storage.

I want to express my wholehearted thanks to all chapter authors for their contributions to this book. Their enthusiasm and willingness to share their knowledge is greatly appreciated. I would also like to extend my gratitude to the project managers, editors, and all other assistants who helped to produce this book. Without their invaluable input, the publication of this book would have been impossible.
