Several other nanoparticles have been studied because physical properties of the nanostructures differ from the bulk materials [5,6]. Metal nanoparticles such as ZnO and titanium dioxide (Ti02), for example, provide nanocomposites the attractive nonlinear properties that make them ideal candidates for nonlinear optical (NLO) based devices [5]. Porous system-based nanocomposites, including porous materials such as silicon, gallium phosphide, aluminum oxide, and structures based on them, were considered by Golovan et al. [6]. The main focus is on the effect of birefringence, which is caused by the anisotropy of pores in the materials.

Nanocomposites of conducting polymers exhibit improved physicochemical and biological properties as compared to their individual counterparts. The integration of secondary component within conducting polymer leads to dramatic increase in different properties that are useful from an application point of view. Size, shape and controlled distribution of the dispersed phase are the critical factors to control the desired properties of a nanocomposite. Different approaches such as in situ synthesis, one-pot synthesis, electrochemical polymerization and vapor-phase polymerization have been employed to synthesize the nanocomposites of conducting polymers with metal or metal oxide nanoparticles, carbon-based materials, ternary nanocomposites, etc. All of these methods have certain advantages and drawbacks. Functional nanocomposites synthesized by these methods display many... 

Incorporation of an inorganic secondary component into the matrix of conducting polymers is a useful approach to improve the functionality of conducting polymer-based nanocomposites. Nanoparticles of metal or metal oxide and other nanostructures such as graphene, carbon nanotubes (CNT) are used as dispersoid within conducting polymer matrix depending on the requirements. The shape, size, aspect ratio and the interfacial adhesion between the matrix and dispersoid affect the properties of the hybrid nanocomposites [28]. The synthesis, properties, and applications of different conducting polymer-based hybrid nanocomposites are discussed below. 

The wide assortment of polymer systans (polypropylene, poly(methyl methacrylate) [PMMA], polyepoxide, polystyrol, PC, etc.) is used as a polymeric matrix for nanocomposites production (Ray and Okamoto 2003). The most well-known fillers of polymeric matrix are nanoparticles (silica, metal, and other organic and inorganic particles), layered materials (graphite, layered aluminosilicates, and other layered minerals), and fibrous materials (nanofibers and nanotubes) (Thostenson et al. 2005). Nanocomposite polymer materials containing metal or metal oxide particles attract growing interest due to their specific combination of physical and electric properties (Rozenberg and Tenne 2008, Zezin et al. 2010). Nanocomposites on the base of layered materials...
