Nanocomposites research

Most nanocomposite researchers obdurately believe that the preparation of a completely exfoliated structure is the ultimate target for better overall properties. However, these significant improvements are not observed in every nanocomposite system, including systems where the silicate layers are near to exfoliated [29]. While, from the barrier property standpoint, the development of exfoliated nanocomposites is always preferred, Nylon 6-based nanocomposite systems are completely different from other nanocomposite systems, as discussed [3,8].

Nanocomposites encompass a large variety of systems composed of dissimilar components that are mixed at the nanometer scale. These systems can be one-, two-, or three-dimensional organic or inorganic crystalline or amorphous. A critical issue in nanocomposite research centers on the ability to control their nanoscale stmcture via their synthesis. The behavior of nanocomposites is dependent on not only the properties of the components, but also morphology and interactions between the individual components, which can give rise to novel properties not exhibited by the parent materials. Most important, the size rednction from microcomposites to nanocomposites yields an increase in snrface area that is important in applications such as mechanically reinforced components, nonlinear optics, batteries, sensors, and catalysts.

The pol5mier nanocomposite field has been studied heavily in the past decade. However, polymier nanocomposite technology has been around for quite some time in the form of latex paints, carbon-black filled tires, and other pol5mier systems filled with nanoscale particles. However, the nanoscale interface nature of these materials was not truly understood and elucidated until recently [2 7]. Today, there are excellent works that cover the entire field of polymer nanocomposite research, including applications, with a wide range of nanofillers such as layered silicates (clays), carbon nanotubes/nanofibers, colloidal oxides, double-layered hydroxides, quantum dots, nanocrystalline metals, and so on. The majority of the research conducted to date has been with organically treated, layered silicates or organoclays.

Due to the excellent redox properties and high conductivity of the conducting polymer nanocomposites, researchers have been extensively investigating them as electrode materials for batteries and supercapacitors [29,30]. Further, the soft porous conductive polymer matrix can efficiently buffer the severe volume changes of active electrode material during the ion intercalation and extraction process, hence improving cyclability of the electrode material and also acts as a conductive binder, decreasing the contact resistance between particles of active material [31]. In this section...

Micron-sized fillers, such as glass fibers, carbonfibers, carbon black, talc, and micronsized silica particles have been considered as conventional fillers. Polymer composites filled with conventional fillers have been widely investigated by both academic and industrial researchers. A wide spectrum of archival reports is available on how these fillers impact the properties. As expected, various fundamental issues of interest to nanocomposites research, such as the state of filler dispersion, filler-matrix interactions, and processing methods, have already been widely analyzed and documented in the context of conventional composites, especially those of carbon black and silica-filled rubber compounds [16], It is worth mentioning that carbon black (CB) could not be considered as a nanofiller. There appears to be a general tendency in contemporary literature to designate CB as a nanofiller - apparently derived from... 

In-situ intercalation method was reported by Toyota researchers for the synthesis of polyamide nanocomposites that led to the exponential growth in the nanocomposites research. For generation of polymer nanocomposites by this method, the layered silicate mineral is swollen in monomer. After swelling, the polymerization of the monomer is initiated. As monomer is present in and out of the filler interlayers, therefore, the generated stmcture is exfoUated or significantly intercalated. As the rate or mechanism of polymerization in and out of the filler interlayers... 

Owing to their unique electronic, thermal, and mechanical properties, CNTs represent ideal candidates for filler material in nanocomposites. Researchers envision utilizing the high aspect ratio and conductivity of nanotubes to develop conductive plastics with very low percolation thresholds. Moreover, thermally conductive composites are a second avenue of nanocomposite research.The most promising area of nanocomposite research, however, involves the use of CNTs as reinforcing fillers for plastics. ...
