The synthesis of polymer nanocomposites is an integral aspect of polymer nanotechnology. By inserting the nanometric inorganic compounds, the properties of polymers improve and hence this has a lot of applications depending upon the inorganic material present in the polymers. The improvements obtained in day/PP nanocomposite structure can make this commercial thermoplastic polymer more suitable for automotive, construction and packaging applications. Different alkyl ammonium surfactants and compatibilizer was used to produce layered silicate/PP nanocomposites by the same melt intercalation technique. 

During the past decades, nanotechnology has attracted great attention due to its marvellous potential applications in numerous areas [90]. Polymer nanocomposite is a unique addition in the nanotechnology family. In polymer nanocomposite, one phase is dispersed in another phase in nanometer level [19]. Different types of reinforcing fillers such as sodium montmo-rillonite, sodium bentonite, layered double hydroxide, exfohated graphite, fullerene, carbon nanofiber, and carbon nanotube have been successfully used in the preparation of polymer nanocomposites [19]. Recently,... 

Thus vegetable oil-based polymer nanocomposites have considerable significance in the development of advanced polymeric materials, offering great improvement in performance characteristics without a large increase in cost. Nanotechnology may therefore carve out a unique niche of its own in the area of vegetable oil-based polymer nanocomposites.

In the large field of nanotechnology, polymer-based nanocomposites have become a prominent area of current research and development for biomedical applications.In principle, nanocomposites are an extreme case of composite materials in which interface interactions between the two phases, the matrix and the reinforcement, are maximized. In the literature, the term nanocomposite is used for polymers with sub-micrometre dispersions. In polymer-based nanocomposites, nanometre sized particles of inorganic or organic materials are homogeneously dispersed as separate particles in a polymer matrix. Researchers have tried a variety of processing techniques to obtain dense polymer nanocomposite films. The incorporation of nanostructures into polymers can generally be done in different ways as indicated below ...

In recent years, the development of semiconductor-polymer nanocomposite materials has become an important research area of nanoscience and nanotechnology as these nanocomposites combine the advantageous properties of polymers with the unique size-tunable optical, electronic, catalytic, and other properties of semiconductor nanoparticles [227-229]. A number of methods are available for producing hybrids of polymers with semiconductor nanoparticles. Two widely used methods, i.e. melt blending and in-situ polymerization, for synthesis of semiconductor-polymer nanocomposites are discussed here.

The term polymer nanocomposites pertains to the synthesis, characterization, and applications of polymeric materials with at least one or more dimensions less than 100 nm. Materials made with dimensions on the nanoscale offer unique and different properties compared to those in the macro scale developed with conventional technology. The field holds a lot of promise not only to the practitioner of the technology but also for inventors and scientists. The benefits to miniaturization, as realized in the microprocessor and microelectronics industry as a result or as part of the computer revolution, are being tapped into by the emergence of nanotechnology. 

Recently, polymer nanocomposites have attracted an increased attention, where nanotechnology is applied to produce materials with remarkable improvements in properties and performance. The most popular approach to produce this new family of composite materials is to introduce nanoscale particles into a polymer matrix to produce polymer/nano-particle composites. Examples of such nanoparticles include layered silicates, layered titanates, carbon nanotubes (CNTs), gold, silver, and maghemite nanoparticles, and fluorine mica [79, 80].
