ABSTRACT
Abstract: Developing environment-friendly and smart materials via a green pathway has been found a considerable interest among material scientists. This reality pushes the research of the world community to make different smart materials. This chapter focuses on three main classes of smart materials including antibacterial, anti-fogging and self-healing materials with emphasis on green chemistry. These coatings and materials are instances of bio-inspired smart materials aimed at improving the quality of human life. However, there are challenging health and environmental issues caused by synthetic, non-degradable and even toxic compounds used in fabrication of such products. Hence, development of smart systems from natural resources such as biopolymers, with antibacterial, anti-fogging
and self-healing capabilities, would be of great importance. In this chapter, rst, the scientic fundamentals of above-mentioned smart materials and coatings are discussed. In the case of antibacterial and anti-fogging materials, the traditional systems and their underlying mechanisms are introduced, besides their environmental and health impact. Finally, recent developments in fabrication of environmentally friendly antibacterial and anti-fogging systems based on natural, non-toxic materials, as alternatives to the traditional ones, are reviewed. Moreover, different aspects of self-healing materials, including chemistry of self-healing, conceptual approach to self-healing and green self-healing materials, are discussed in detail, which may be helpful for further developments of smart materials in the future.
