In addition to the recast samples, as-received, melt extruded films of the nylon 6 and nylon 6/layered silicate nanocomposite (7.5wt%) were exposed to the oxygen plasma. The nylon 6 nanocomposite develops of a colorful, interferometric surface reflection upon exposure (not shown). The optical interference effects suggest highly uniform alteration of the surface composition on the order of 200-500 nm.

Although mechanical performance of composites can depend on the processing conditions, the batch-mixed and the twin-screw extraded nanocomposites developed in this study did not show any significant ddfeience. Also, we note that while the nanocomposites were generally less flexible as compared to the pure LLDPE, they still retained a fairly high elon tion-at-break of about 140%, compared to about only 30% displayed by short P-55 carbon fiber composites. Coupled with an EM SE of about 22-24 dB, PR-19 HT and MWNT HT nanocomposites indicate a potential in applications that require significant mechanical flexibility.

Besides the utilization of PANI/Sn02 as a humidity sensor device, many scientific works emphasized that nanocomposites developed from polyaniline (PANI) and metal oxides—especially Sn02—are good candidates as gas sensor deviees. Taking into account all these observations, the literature supports fabrication of PANI/Sn02 hybrid materials with different amounts of Sn02 content prepared by in situ chemical oxidative polymerization method, with the sensitivity of materials toward toluene... 

Finally, the remarkable mechanical properties and reinforcing potential, renew-ability, biobased nature, biodegradability and unique nanostructured porous network of BC make it a perfect candidate for polymer and hybrid nanocomposites development. In this sense, extensive research has been carried on the design of innovative BC nanocomposite materials with improved and functional properties, by combination with several natural and synthetic polymers as well as inorganic nanophases, for a wide range of biomedical and technological applications. This will be the object of the two coming sections. 

Nanomaterials, as described here, are defined as materials with at least one of three dimensions <100 nm. Spherical nanoparticles, such as alumoxanes or silica nanoparticles, are nano-sized in aU three dimensions. Nanotubes (carbon nanotubes), rods, or needles (HA) have two nanometer-sized dimensions. Nanosheets, such as layered sihcates, have only one dimension in the nanoscale. Each of these nanomaterials offers mechanical reinforcement or osteoconductivity by dispersing into a matrix and chemically interacting with the macroscopic material. However, these particles are typically hydrophilic while the macroscopic material into which they are dispersed is usually hydrophobic. Thus, nanomaterial dispersion and promotion of interactions between the nanofiUers and the macroscopic material are the two primary challenges for nanocomposite development.
