In addition to forming functional nanocomposites and optical materials, LLC systems also have value in the area of catalysis. LLC phases have a number of features that make them amenable for accelerating chemical reaction rates. For example, LLC phases have regular nanometer-scale water- or polar solvent-filled cavities and hydrophobic domains of uniform size that are close in size to typical small molecule substrates. These domains can afford confined environments to encapsulate reactants and catalytic entities, thereby increasing their local concentration and the probability of productive colli-... 

Polymer nanocomposites are combinations of polymers containing inorganic or organic fillers of definite geometries (fibres, flakes, spheres, particulates and so on). The use of fillers, which have one dimension on the nanometre scale, enables the production of polymer nanocomposites. Functional nanocomposites with specific properties can be custom-made by combining metal nanoparticles (MNP) into the polymer matrix. 

In this section, thermal molecular motion at the interface with solid substrates is discussed. It is needless to say that the issue is of pivotal importance for inherent scientific interest because motion at the interface seems to be totally different from that at the polymer surface. Also, the interface between polymers and inorganic materials is crucial in designing and constructing highly functionalized nanocomposites [43-45], which are now used for biomaterials [46, 47], sensors [48,49], power sources [50,51], etc., in addition to their popular and traditional use as structural materials [43-45, 52, 53]. 

Successful incorporation of magnetic nanoparticles into a conductive polymer matrix will definitely widen their applicability in the fields of electronics, biomedical dmg delivery, and optics. These doubly functionalized nanocomposites will exhibit the magnetic properties of the magnetic particles and the conducting properties of the conductive-polymer matrices. However, one of the challenges so far is the abihty to integrate a high... 

Novel applications in science and technology require highly efficient and, if possible, environmentally friendly methods and techniques for the generation of functional nanocomposite materials. Serving the environmental aspect, water-based formulation techniques that avoid the use of organic solvents are the focus of attention. Besides the well-known water-based emulsion and mlcroemul-sion polymerization processes, the miniemulsion polymerization technique is a highly versatile heterophase system that is suitable for the preparation of complex nanoparticles.

Abstract Aerogels are regarded as ideal candidates for the design of functional nanocomposites based on supported metal or metal oxide nanoparticies. The large specific surface area together with the open pore structure enables aerogels to effectively host finely dispersed nanoparticies up to the desired loading and to provide nanoparticle accessibility as required to supply their specific functionalities. 

It is important to point out that the role of the silica matrix was not limited to the stabilization and isolation of the alloy nanoparticles. In fact, the collective properties of those functional nanocomposites could be tuned as a function of the concentration of the magnetic phase, as well as the relative distance between the nanoparticles, which in turn... 

Considerable improvement has been achieved in the design of functional nanocomposites based on aerogel dielectric matrices, in terms of range of accessible compositions, control over nanoparticle size, distribution and loading, and tailored porous texture. 

In the past few years, it has been demonstrated that vast potential exists for the discovery of novel nanocomposite materials as well as for the development of new technology centered on functional nanocomposites, which can result in fast progress of these materials on the consumer market. Nowadays, our ability to control the structures and properties of nanocomposites is limited only by our knowledge of manipulation of these nanoscale structures. This area of research will clearly lead to further commercial applications with meaningful economic effect driven by materials with new combinations of properties. 

MMT nanoparticles are well known to be a mixture of several natural compounds with nonuniform composition and particle size [27]. For example, MMT minerals from different deposits might differ considerably in composition. This variation in composition of MMT significantly complicates the task of making functional nanocomposites with prescribed properties for targeted applications. Therefore, there is a need to develop synthetic nanofillers with prescribed particle composition, shape, and size for use as fillers in polymer nanocomposites with well-defined properties. In this area, synthetic nanodimensional silicates may provide a number of opportunities in polymer nanocomposites that is relatively little studied and poorly understood relative to the well-studied polymer nanocomposites filled with natural layered MMTs [28-32]. In contrast to the commonly used layered MMT compounds, it is envisaged that use of nanoparticles with different morphology (e.g.,...
