Description:
Metal nanomaterials have attracted considerable attention because of their unique magnetic, optical, electrical, and catalytic properties and their potential applications in nanoelectronics as well as in various wet chemical synthesis methods. There is also great interest in synthesizing metal and semiconductor nanoparticles due to their extraordinary properties—properties which are different than when they are in bulk. Green chemistry principles are also regaining popularity for this type of synthesis. Green chemistry is the design, development, and implementation of chemical products and processes in order to reduce or eliminate the use and generation of substances that are hazardous to human health and to the environment. An example of a greener application of metal nanoparticles is the use of silver and gold nanoparticles, produced from vegetable oil, that are being used in antibacterial paints. Polymer inorganic nanocomposites have also attracted a lot of attention recently due to their unique, size-dependent chemical and physical properties. Different methods of preparing novel nanocomposites with desired properties and functions have been developed . Such methods should produce materials in which the unique properties of the nanoparticles are preserved. One of the main approaches is the dispersion of the previously prepared nanocrystals in polymers. Another is the generation of nanocrystals in polymers in situ. In the latter approach, various nanocables, nanowires and nanoparticulates, generated in situ, have been reported.
