Thus, thermal methods for synthesis of nanoparticles in a polymer matrix possess unlimited opportunities for the construction of polymer nanocomposites and for a choice of the optimal variant. In this chapter we did not analyze sol-gel synthesis of nanocomposites as well as hybrid polymer-inorganic nanocomposites, in preparation of which the controlled thermolysis plays an important role. 

Soft nanohybrid materials with novel organic-inorganic network structures, such as nanohydrogels, soft nanocomposites (solid), and their derivatives are described in the chapter Soft Nanohybrid Materials Consisting of Polymer-Clay Networks. Synthesis of polymer hybrids based on metal-oxide nanoparticles are discussed in Fabrication of Metal Oxide-Polymer Hybrid Nanocomposites. Some properties and applications of these hybrid nanocomposites are also discussed in this chapter. 

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. 

To fabricate different polymer layers in a device using solution based techniques, mutually exclusive solvents have to be identified, which is often very difficult. CVD eliminates these difficulties and excellent heterojunctions and multilayered films can be fabricated relatively easily. Also, the capability to co-deposit compounds can be achieved. This ease of co-depositing compounds has enabled the synthesis of several inorganic-organic hybrids, which can also be tailored as nanocomposites at the molecular level. 

Abstract Semiconductor nanoparticles have attracted much attention due to their unique size and properties. Semiconductor-polymer hybrid materials are of great importance in the field of nanoscience as they combine the advantageous properties of polymers with the unique size-tunable optical, electronic, catalytic and other properties of semiconductor nanoparticles. Due to combination of the unique properties of organic and inorganic components in one material, these semiconductor-polymer hybrids find application in environmental, optoelectronic, biomedical and various other fields. A number of methods are available for the synthesis of semiconductor-polymer hybrid materials. Two methods, i.e. melt blending and in-situ polymerization, are widely used for the synthesis of semiconductor-polymer nanocomposites. The first part of this review article deals with the synthesis, properties and applications of semiconductor nanoparticles. The second part deals with the synthesis of semiconductor-polymer nanocomposites by melt blending and in-situ polymerization. The properties and some applications of semiconductor-polymer nanocomposites are also discussed. 

Melt blending is the most simple and conventional method for the synthesis of various polymer hybrids with inorganic nanoparticles, including semiconductor nanoparticles. In melt processing, inorganic nanoparticles are dispersed into the polymer matrix and then polymer nanocomposites are obtained by extrusion. Figure 10 shows a representation of melt blending for the synthesis of polymer nanocomposites [230]. 

A classification of methods for preparing polymer-layered inorganic solid compounds takes into account the main processes involved in the synthesis of the final hybrid material. The nature of both the 2D host solid and the guest polyma- determines the pathway applicable to obtain a particular nanocomposite and, in certain cases, is decisive in the behavior of the resulting material.
