In recent years, there has been a veritable explosion of research and development in consumer-oriented fields that utilize polymeric materials which absorb large amounts of water. These fields encompass the preparation, characterization and commercialization of separation systems, pharmaceutical and personal care products such as infant diapers, feminine products, incontinence products and many other related areas. The polymeric materials utilized in these applications are known as absorbent or superabsorbent materials because of their ability to swell rapidly and to retain large volumes of water, urine and other biological fluids.The aim of this book is to introduce the fundamentals of polymer structure and swelling as related to polymers used for these superabsorbent materials. In the field of absorbence, particular attention is given to crosslinked structures which swell to more than fifty times their initial weight in water or electrolytic solutions. The book also provides descriptions of novel applications of superabsorbent materials as well as a detailed analysis of water transport in crosslinked polymers.Absorbent Polymer Technology should be of interest to chemists, polymer scientists, chemical engineers, and industrial scientists working with swellable polymeric systems in personal care, pharmaceutical, agricultural waste treatment and separation industries.

This book discusses fundamental aspects of super absorbent polymers (SAPs), insight into the synthesis and modification of SAPs as well as their potential applications in different domains. SAPs are bio-based material that has attracted much interest due to their unique structural properties, biodegradability, biocompatibility, etc. The book exhibits a unique combination of SAP designing, synthetic strategies, properties and chemistry along with SAP’s application in the field of drug delivery, firefighting and biosensors, agriculture, etc. Various approaches to make these products a cost-effective and sustainable are discussed precisely in this book. Additionally, the approaches from the perspective of academic organization and research laboratories, many readers are able to learn the insights of the connection between super absorbent polymers in the agriculture field by reducing seedling mortality owing to their water storage capacity in soil. This book written by eminent researchers can be a useful reference for graduate, post-graduate students and researchers working in the file of super absorbent polymers, polymer technology, hygiene industry, etc.

This is the state-of-the-art report prepared by the RILEM TC “Application of Super Absorbent Polymers (SAP) in concrete construction”. It gives a comprehensive overview of the properties of SAP, specific water absorption and desorption behaviour of SAP in fresh and hardening concrete, effects of the SAP addition on rheological properties of fresh concrete, changes of cement paste microstructure and mechanical properties of concrete. Furthermore, the key advantages of using SAP are described in detail: the ability of this material to act as an internal curing agent to mitigate autogenous shrinkage of high-performance concrete, the possibility to use SAP as an alternative to air-entrainment agents in order to increase the frost resistance of concrete, and finally, the benefit of steering the rheology of fresh cement-based materials. The final chapter describes the first existing and numerous prospective applications for this new concrete additive.

This book examines the synthetic approaches, properties, applications, and recyclability of bio-based superabsorbent polymers (SAP) in depth. It describes and compares bio-based SAPs with petro-based SAPs. Additionally, it explores the structure–property relationships of bio-based SAPs derived from various natural sources. The book covers current and emerging applications in health and hygiene products, agriculture, construction, and other areas. It also explores the recycling and reusing methods available for water recovery, pressure sensitive adhesives, etc. It discusses the issues behind the sharp increase in research attention, namely the prevailing research hotspots/clusters and suggestions with regard to present studies, works that have been significant and pivotal in the development of SAP research, and the current advances and future directions of research. It also presents the emerging applications of superabsorbent polymers.

From the utilization of textile waste to the high-tech product - this is how modern nonwovens can best described. Web formation and web bonding processes have recently being enhanced. Nowadays, fibres, granulates, binder and finishing agents are used. This development entails a wider range of applications in the fields of hygiene, medicine, the garment-producing and building industries, interior design as well as further technical uses. This book provides comprehensive information about nonwovens, from the raw material fibres via the manufacturing processes to finishing and to the ready-made product. Nonwoven characteristics and the fields of application are discussed in detail as well as the processes available to test the raw materials, the intermediate and the final products. This book will be the standard reference on nonwovens in the years to come!
