The development of polymer composites containing inhibitors of metal corrosion is an important endeavor in modern materials science and technology. Corrosion inhibitors can be located in a polymer matrix in the solid, liquid, or gaseous phase. This book details the thermodynamic principles for selecting these components, their compatibility, and their effectiveness. The various mechanisms of metal protection - barrier, inhibiting and electromechanical - are considered, as are the conflicting requirements placed on the structure of the combined material. Two main classes of inhibited materials (structural and films/coatings) are described in detail. Examples are given of structural plastics used in friction units subjected to mechano-chemical wear and of polymer films/coatings for protecting metal objects against corrosion.

This book is devoted to a nontraditional class of materials which are manufactured by the melt-blowing process - i.e. by extrusion of polymer melt followed by fiber stretching with a gas stream. For the first time extensive data on classical and modern modifications of this technology are generalized and a review is given of extrusion head dies and subsidiary equipment. The text examines the structure and main properties of melt-blown materials as conditioned by peculiarities of overheated polymer melt spraying in an oxidizing medium. Information is given about filtering mechanisms and the main types of polymer fibrous filtering materials: electret, magnetic, adsorptional, bactericidic, and about carriers of microorganisms in biofilters. Social and ecological aspects of the application of melt-blown materials are analyzed.
