“…In addition to studies on specific properties [1-3,32-66], a number of simulation studies on preparation and properties of these new materials [54][55][56][57][58][59][60][61][62][63][64][65][66] can be found. Tables 2 and 3 [2,67,68] show some of the properties for a few polymer-layered nanocomposites synthesized by different methods mentioned above.…”

“…Flame retardancy of polyamide 6 is mostly required in electric industries, with typical applications in electrical connectors, terminal blocks, small electrical housings, clip fasteners, switch components, wire ties, and many other industrial parts. 1 Polymer layered silicate nanocomposites have attracted a great deal of interest over the last few years as a result of the potentially superior properties. Numerous studies have shown that a very low percentage of layered silicates can lead to a significant enhancement of many properties, such as stiffness, strength, flame retardancy, gas barrier properties, ionic conductivity, thermal stability, and tunable biodegradability.…”

In this paper, polyamide-6 and polyamide-6 nanocomposites were prepared by direct melt intercalation technique. The thermal degradation behavior of both polyamide-6 and polyamide-6 clay nanocomposites has been studied. The apparent activation energy of the nanocomposites is almost the same with that of pure polymer under nitrogen, but the apparent activation energy of the nanocomposites is greatly enhanced in air atmosphere. This increasing trend coincides with the thermal analysis and the cone calorimeter results, which may suggest that the polymer/clay nanocomposites have a higher thermal stability and lower flammability. The kinetic analysis also indicates that the pyrolytic degradation and the thermal oxidative degradation of PA6 and PA6/ OMT nanocomposites are two kinds of different reaction models.

“…These improvements include a high modulus, increased strength and thermal stability, decreased gas permeability and flammability, and increased biodegradability of biodegradable polymers. [7][8][9][10][11][12][13][14] Montmorillonite (MMT)-based clays were used for the preparation of the nanocomposites in this study. MMT is a naturally occurring 2 : 1 phyllosilicate, which has the same layered and crystalline structure as talc and mica but a different layer charge.…”

Nanocomposites based on thermoplastic elastomeric polyurethane (TPU) and layered silicate clay were prepared by in situ synthesis. The properties of nanocomposites of TPU with unmodified clay were compared with that of organically modified clay. The nanocomposites of the TPU and organomodified clay showed better dispersion and exhibited superior properties. Exfoliation of the clay layers was observed at low organoclay contents, whereas an intercalated morphology was observed at higher clay contents. As one of major purposes of this study, the effect of the silicate layers in the nanocomposites on the order-disorder transition temperature (T ODT ) of the TPU was evaluated from the intensity change of the hydrogen-bonded and free carbonyl stretching peaks and from the peak position change of the NÀ ÀH bending peak. The presence of the organoclay increased T ODT by approximately 108C, which indicated improved stability in the phase-separated domain structure. The layered silicate clay caused a tremendous improvement in the stiffness of the TPU; meanwhile, a reduction in the ultimate elongation was observed.
