Special attention in studying nanocomposite properties usually attracts to allocation of organomodified layered silicates on polymer matrix which plays important part due to depending of this properties on allocation. 

The influence of nanooxides on the photoelectric properties of nanocomposites is explained with regard to the fact that Ti02 partides usually form a type-11 heterojunction with a polymer matrix, which essentially results in the separation of nonequilibrium electrons and holes. Embedding Si02 particles results in stabilization of the nanocomposite properties and... 

The control of nanoparticle morphology becomes a very important aspect, since morphology profoundly influences the material performance. As a longterm goal the development of synthesis schemes able to control particle size, shapes, and composition independently from one another is very important, in order to allow tuning of nanocomposite properties. 

Obstacles to greater nanofiller use remain, and just explaining these challenges requires a new set of terminology. The main issue is that nanofiller partides are difficult to disperse meaning that actual nanocomposite properties may not reach their potential or theoretical properties. For example, for proper dispersal, sheet-like nanoday platelets must be exfoliated, physically or chemically, to separate them into individual layers. This issue is probably the most discussed and most problematic obstade impeding the full commerdal-ization of nanocomposite compounds, since the full surface area of each separated sheet or platdet is what creates optimum properties [7-31, 7-32[.

The preparation methods have crucial impact on the dispersion of the nanofillers and the final properties of the nanocomposites. In this section, the morphology of the PP nanocomposites and various nanocomposite properties will be discussed.

In the past decade, clay-based polymer nanocomposites have attracted considerable attention from the research field and in various applications. This is due to the capacity of clay to improve nanocomposite properties and the strong synergistic effects between the polymer and the silicate platelets on both a molecular and nanometric scale [2,3], Polymer-clay nanocomposites have several advantages (a) they are lighter in weight than the same polymers filled with other types of fillers (b) they have enhanced flame retardance and thermal stability and (c) they exhibit enhanced barrier properties. This chapter focuses on the polymer clay-based nanocomposites, their background, specific characteristics, synthesis, applications and advantages over the other composites. 

Polymer nanocomposite properties are related to a variety of parameters, among which the most important are the features of the constituent phases, the dispersion and the interfacial interaction between the nanomaterials and the matrix [33,39], Nanomaterials tend to agglomerate due to Van der Waals forces in order to achieve a stable dispersion in polymers that lack a permanent dipole moment or suitable mechanism to favorably interact with carbon nanomaterials, physical or chemical modification of either the nanofiller or the polymer matrix is necessary [39],...
