Nanomaterials: Properties, Preparation and Applications

Abstract

The area of nanoparticle properties and preparation is vast and there are entire journals dedicated to publishing work in this area. In addition, the wide number of potential applications and proposed extensive use and implementation of nanotechnology means that an in -depth analysis of the whole area is beyond the scope of this chapter. Given the broad audience this book is intended for, this chapter aims to provide a comprehensive overview of the area with the purpose of highlighting important issues faced when studying these materials. Review articles have been cited for many of the areas discussed so that the reader may expand their knowledge further by more in -depth reading on areas of specifi c interest. A holistic approach to the content has been adopted to provide the reader with an overview of the key areas pertinent to the subject regardless of background.To achieve this, what a nanoparticle is and what it is not is discussed fi rst. What properties of nanoparticles are key to their function are then examined and some of the unusual properties these particles may possess are highlighted. The challenges facing nanoparticle production are then examined, taking a closer look at several common methods. The preparation of some common types of nanoparticles is discussed and, fi nally, the application of these nanoparticles in devices and formulations is reviewed. This approach is designed to aid the full understanding of the function and properties of the nanomaterials in their fi nal applications.

Emerging Trends in Smart Self-Healing Coatings: A Focus on Micro/Nanocontainer Technologies for Enhanced Corrosion Protection

“…Interfacial polymerization is particularly well suited for large-scale production of organic capsules. This method involves a reaction at the interface between two incompatible solutions, each containing different monomers for the shell and core [29]. Capsules with the encapsulated agent at the core are formed at this interface.…”

Zinc-Based Nanomaterials for Diagnosis and Management of Plant Diseases: Ecological Safety and Future Prospects

“…The reason for the unusual properties of nanomaterials may be attributed to the basic phenomena of “quantum confinement” and “surface-interface effects” [ 34 , 35 , 36 ]. These two characteristics may alter the mechanical, optical, electrical, magnetic, and chemical catalysis properties of nanoscale materials compared to their bulk counterparts [ 37 , 38 ]. Thus, nanomaterials exhibit properties that are size dependent, i.e., the size of grain or particles, phase inclusions, pores, or other morphological features affect the properties exhibited by the substance [ 39 ].…”
