The first edition of Health and Environmental Safety of Nanomaterials: Polymer Nanocomposites and Other Materials Containing Nanoparticles was published in 2014, but since that time, new developments in the field of nanomaterials safety have emerged, both at release and exposure, along with the expanding applications of the nanomaterials side. Numerous studies have been dedicated to the issue of biophysical interactions of nanoparticles with the human body at the organ, cellular, and molecular levels. In this second edition, all the chapters have been brought fully up to date. There are also four brand new chapters on the biophysical interaction of nanoparticles with the human body; advanced modeling approaches to help elucidate the nanorisks; safety measures at work with nanoparticles; and the health and environmental risks of graphene. It provides key knowledge and information needs for all those who are working in the research and development sector and need to learn more about the safety of nanomaterials. Focuses on the health and safety of polymer nanocomposites and other materials containing nanoparticles, as well as their medical and environmental implications Discusses the fundamental nature of various biophysical interactions of nanoparticles with the human body Looks at the physico-chemistry of nanoparticles and their uptake, translocation, transformation, transport, and biodistribution in mammalian and plant systems Presents the structure-activity relationships and modeling of the interactions of nanoparticles with biological molecules, biochemical pathways, analysis of biomolecular signatures, and the development of biomarkers

Thermal Degradation of Polymeric Materials, Second Edition offers a wealth of information for polymer researchers and processors who require a thorough understanding of the implications of thermal degradation on materials and product performance. Sections cover thermal degradation mechanisms and kinetics, as well as various techniques, such as thermogravimetry in combination with mass spectroscopy and infrared spectrometry to investigate thermal decomposition routes. Other chapters focus on polymers and copolymers, including polyolefins, styrene polymers, polyvinyl chloride, polyamides, polyurethanes, polyesters, polyacrylates, natural polymers, inorganic polymers, high temperature-resistant and conducting polymers, blends, organic-inorganic hybrid materials, nanocomposites, and biocomposites.

Finally, other key considerations such as recycling of polymers by thermal degradation, thermal degradation during processing, and modelling, are discussed in detail.

Explains mechanisms of polymer degradation, making it possible to understand and predict material behavior at elevated temperatures Offers systematic coverage of each polymer group that is supported by data detailed explanations and critical analysis Investigates thermal decomposition routes in new materials, such as organic-inorganic hybrid materials and polymer nanocomposites

Health and Environmental Safety of Nanomaterials addresses concerns about the impact of nanomaterials on the environment and human health, and examines the safety of specific nanomaterials. Understanding the unique chemical and physical properties of nanostructures has led to many developments in the applications of nanocomposite materials. While these materials have applications in a huge range of areas, their potential for toxicity must be thoroughly understood.

Part one introduces the properties of nanomaterials, nanofillers, and nanocomposites, and questions whether they are more toxic than their bulk counterparts. Part two looks at the release and exposure of nanomaterials. The text covers sampling techniques and data analysis methods used to assess nanoparticle exposure, as well as protocols for testing the safety of polymer nanocomposites. It explains characterization techniques of airborne nanoparticles and life cycle assessment of engineered nanomaterials. Part three focuses on the safety of certain nanomaterials, including nanolayered silicates, carbon nanotubes, and metal oxides. In particular, it explores the potential ecotoxicological hazards associated with the different structures of carbon nanotubes and the safe recycling of inorganic and carbon nanoparticles. The final two chapters address the risks of nanomaterials in fire conditions: their thermal degradation, flammability, and toxicity in different fire scenarios.

This is a scientific guide with technical background for professionals using nanomaterials in industry, scientists, academicians, research scholars, and polymer engineers. It also offers a deep understanding of the subject for undergraduate and postgraduate students.
