Self-healing phenomenon, adapted from living things, was for a long time an interesting topic of discussion on the potential improvements of human-made products, but for quite a while it became applicable reality useful in many manufactured product.

The book has three major sections organized in fifteen chapters. The first section contains chapter which discusses the well-established mechanisms of self-healing which can be potentially applied in the development of new materials that have an ability to repair themselves without or with minimal human intervention. All theoretical background required and known to-date to understand these principles is included in this section. The full chapter on chemical and physical changes which occur during self-healing are also discussed and it belongs to this section.

The second part of this book compares parameters of different self-healing technological processes. The process parameters discussed include fault detection mechanisms, methods of triggering and tuning of the healing processes, activation energy of self-healing processes, the means and methods of delivery of the healing substances to the defect location, self-healing timescale (rate of self-healing), and the extent of self-healing (healing efficiency, recovery of properties, etc.). Each of these topics is discussed in a separate chapter.

The third part is devoted to the mathematical modeling of the processes of self-healing (molecular dynamics simulation), the morphology of healed areas, and the discussion of application the most important analytical techniques to the evaluation of the self-healing process.

The final section of the book includes practical advice on the selection of additives for self-healing formulation, methods of self-healing of different polymers and application of self-healing technology in different groups of the products. This part is based on the practical knowledge, the existing patents, the published paper, and the practical application notes. Thirty polymers and twenty-seven groups of products are selected for this discussion based on their frequency of application of the technology of self-healing.

The expected audience for this book includes people working in the industries listed in chapter 15 and on the polymers listed in chapter 14 (see the table of contents below), university professors and students, those working on the reduction of wastes and recycling, and all environmental protection agencies.
