Multifunctional Phase Change Materials: Fundamentals, Properties and Applications updates on phase change materials (PCMs) used for the storage of thermal energy as sensible and latent heat. This class of materials is the subject of intensive research, both fundamental and applied, as they substantially contribute to the efficient use and conservation of waste heat and solar energy. Different groups of materials have been investigated as PCMs, including inorganic systems (salt and salt hydrates), organic, e.g., paraffins or fatty acids, polymers, and finally, hybrid materials. Recent developments are focused on multifunctional PCMs that provide functional features apart from energy storage, such as desired optical or antibacterial properties. This book presents various synthesis approaches for functionalized materials, as well as specific interactions and self-organization effects in polymer/functionalized (nano)particle systems. It reviews the current state-of-the-art in multifunctional phase change materials for thermal energy storage applications by describing the fundamentals of energy storage, the main classes of PCMs, functionalization protocols, encapsulation methods and shape stabilization procedures. Covers the most important developments in PCMs that have expanded rapidly over the last few years, including thermochromic and thermoelectric PCMs, as well as fluorescence-functionalized phase change materials Includes the newest solutions in PCMs related to functionalization and shape stabilization, e.g., nano-encapsulation and electrospun ultrafine phase change fibers Provides a multidisciplinary, comprehensive work that will be of interest for a wide readership active in various disciplines, from materials science to environmental engineering

Today, the application of phase change materials (PCMs) has developed in different industries, including the solar cooling and solar power plants, photovoltaic electricity systems, the space industry, waste heat recovery systems, preservation of food and pharmaceutical products, and domestic hot water. PCMs use the principle of latent heat thermal storage to absorb energy in large quantities when there is a surplus and release it when there is a deficit. This promising technology has already been successfully implemented in many construction projects. The aim of this book is to assist the scientists and to provide the reader with a comprehensive overview of the properties that characterize the phase change materials from theoretical and experimental perspectives with a focus on their technological applications. The present status and future perspectives of phase change material are discussed.

Phase change materials (PCMs) are considered one of the most promising energy storage methods owing to their beneficial effects on a larger latent heat, smaller volume change, and easier controlling than other materials. PCMs are widely used in solar energy heating, industrial waste heat utilization, energy conservation in the construction industry, and other fields. To avoid leakage, phase separation, and volatile problems of PCMs, the encapsulation technique typically uses organic polymer materials as shell structures of microcapsules. Furthermore, using inorganic materials to enhance the thermal property of phase change microcapsules is a popular approach in recent research. Especially, graphene oxide (GO) with high thermal conductivity was used as a common thermal conducting additive to improve the thermal performance of phase change microcapsules. Due to its amphiphilic property, GO combined with PCM microcapsules can achieve a variety of nanostructures for thermal energy storage. In this paper, four aspects have been summarized: configuration of PCMs, methods of combining GO with phase change microcapsules, position and content of GO, and applications of PCM/GO microcapsules. This work attempts to discuss preparation methods and heat-conducting properties of the PCM/GO microcapsules, which helps to better promote the application-targeted design and greatly improve the thermal properties of PCM microcapsules for various applications.
