Mechanochemical Synthesis of Composite Materials

Mechanochemical treatment is one of the modern promising directions of the chemical and technological processes of obtaining a new substance as a result of the transformation of mechanical energy into the chemical and physical processes of system restructuring. The peculiarity of the state of solid matter as a result of intensive mechanical action is determined not only by its destruction, i.e. dispersing and obtaining a powder material with a high new and active surface, but also accumulation of defects in the entire volume of particles, which increases their reactivity. In this book, we present materials of many years of research on the mechanochemical synthesis of composite systems, consisting of inorganic and organic components, obtained by the scientific team of the Institute of Combustion Problems. The book contains, first of all, general ideas about the mechanochemical process and the phenomena accompanying it. The main provisions of structural rearrangement and modification of the surface of dispersible particles are considered, as well as thermodynamics of mechanochemical treatment of materials. Then, using the example of a number of natural minerals, it is shown how mechanochemical treatment can radically change their structure and properties, using various organic compounds as modifiers. Particular attention is paid to the use of ultrasonic treatment, as a kind of mechanical action in a liquid medium on a solid.

Key Features:

• A stand-alone, monograph present results on the mechanochemical synthesis of nanostructured composite materials on the base of inorganic and organic components.
• The book summarizes and systematizes the results of a fundamentally new complex approach to the creation of composite polymer-inorganic systems by mechanochemical treatment, both as a result of the traditional approach with the use of dynamic mills (mechanical reactors) and ultrasonic action on powder mixtures.
• In addition, the book will present a chapter that will focus on the method of mechanochemical preparation of materials for high-energy systems, which are the most promising, since it allows the most productive management of the formation of new structural compositions that increase the energy intensity of the system.
