Description
Book SynopsisThe object of this book is to provide a comprehensive reference source for the numerous scientific communities (engineers, researchers, students, etc.) in various disciplines which require detailed information in the field of dielectric materials.
Part 1 focuses on physical properties, electrical ageing, and modeling - including topics such as the physics of charged dielectric materials, conduction mechanisms, dielectric relaxation, space charge, electric ageing and end of life (EOL) models, and dielectric experimental characterization.
Part 2 examines applications of specific relevance to dielectric materials: insulating oils for transformers, electro-rheological fluids, electrolytic capacitors, ionic membranes, photovoltaic conversion, dielectric thermal control coatings for geostationary satellites, plastics recycling and piezoelectric polymers.
Trade Review“Students, engineers, and materials scientists will find this book to be a good comprehensive resource for learning about the fundamental material property characteristics of dielelectric materials.” (IEEE Electrical Insulation Magazine, 1 July 2014)
