Synthetic polymer films are most widely used as materials for the production of stable charged films. One of the simplest and most widespread methods for charging the polymers involves the use of corona discharge in air at room temperature. The corona discharge creates high energy oxygen-containing charged particles, which are accelerated by the electric field of the corona and then interact with the surface of the polymer films. This book is a review of three aspects of synthetic polymer films changes initiated by corona charging, as well as their possible applications.

This book provides the reader with a working knowledge sufficient to select microbeam techniques for the efficient, cost-effective solution of complex problems arising in today's high-tech industries. Primarily written for the industrial analyst whose field of expertise is other than microbeam analysis, it will also be of help to engineers, plant chemists and industrial research scientists who often seek the aid of the microbeam analyst in their problem solving. Research and plant managers as well as administrators may also find this book helpful since they may be called upon to select and/or approve high-priced microbeam instruments. The book is organized into two parts. Part I gives a brief description of the various techniques and critically compares their capabilities and limitations. Part II consists of selected applications which show how the various techniques or their combinations are applied to characterize materials and to guide research in a wide variety of fields. The examples and case histories will undoubtedly aid the reader in problem solving, quality assurance and research-related tasks. Newcomers to the field will find enough information in the book to enable them to begin practical work and to apply the techniques.

Updated throughout to reflect advances over the last decade, the Fifth Edition continues the handbook’s tradition of authoritative coverage of fundamentals, production methods, properties, and applications of plastics and polymer-based materials. It covers tooling for plastics fabrication processes, thermoplastics, thermosetting plastics, foamed plastics, reinforced plastics, plastisols, and new developments in mold design. It also discusses rubber compounding and processing technologies. More recent developments in polymer fabrication and processing, including electrospinning, electrografted coating, polymer-metal hybrid joining, flex printing, and rapid prototyping/ 3D printing, are also presented. The handbook highlights advanced materials including natural and synthetic gfnanosize polymers, their unusual properties, and innovative applications, as well as polymer-carbon nanocomposites, graphene-based polymer nanocomposites, smart healable polymer composites, smart polymer coatings, electroactive polymers, polymer nanomaterials, and novel nano-/microfibrillar polymer composites. It offers updates on polymer solar battery development, plastics recycling and disposal methods, new concepts of "upcycling" and single-polymer composites, renewable synthetic polymers, biodegradable plastics and composites, and toxicity of plastics. The book also provides an overview of new developments in polymer applications in various fields including packaging, building and construction, corrosion prevention and control, automotive, aerospace applications, electrical and electronic applications, agriculture and horticulture, domestic appliances and business machines, medical and biomedical applications, marine and offshore applications, and sports.
