“…Also the synthesized clay crystals, generated by the self-assembly process, have tendency to aggregate. Therefore this method is not widely used and only a few nanocomposites using hectorite clay and poly (vinyl alcohol), polyaniline and polyacrylonitrile have been synthesized by this method (Alexandre & Dubois, 2000;Lagaly, 1999;Zanetti et al, 2000).…”

“…These nanomaterials can be, in fact, exfoliated into single layers, each of them having thickness of the order of 1 nm, and the surface of the layers may be functionalized by ion exchange or grafting reactions with organic groups that increase the compatibility with the polymers [4]. In addition, layered solids may intercalate polymeric chains into their interlayer regions [5]. The nanocomposites then formed exhibit improved performance compared with virgin polymers: improved flexural modulus, increased heat distortion temperature (HDT), decreased permeability and improved fire properties.…”

Abstract:Polyethylene (PE) was modified by the addition of a layered double hydroxide of zinc aluminum oleate (ZnAl) and/or commercial fire retardants.NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript. The published version may be accessed by following the link in the citation at the bottom of the page.Polymer Degradation and Stability, Vol. 94, No. 5 (May 2009): pg. 782-788. DOI. This article is © Elsevier and permission has been granted for this version to appear in e-Publications@Marquette. Elsevier does not grant permission for this article to be further copied/distributed or hosted elsewhere without the express permission from Elsevier. 2Commercial additives included: melamine polyphosphate (MPP), ammonium polyphosphate (APP), triphenol phosphate (TPP), resorcinol diphosphate (RDP), decabromophenyl oxide (DECA) and antimony oxide (AO). The thermal stability and the combustion behaviors of the new composite polymeric materials are evaluated in TGA experiments and cone calorimetry. At 20% total additive loading, APP and LDH enhance the thermal stability of the PE composites and favor char formation. ZnAl leads to the best reduction in the peak of heat release rate (PHRR), 72%, while the combinations of PE with other additives give reductions in the range 20-40%. The combination of DECA and AO effectively increases the time to ignition and time to PHRR while LDH lowers these two parameters. APP and MPP on the other hand, do not affect the time to ignition, but they effectively increase the time to PHRR relative to the pristine polymer.

“…Nanocomposites could dramatically induce improvements in mechanical and electrical properties, heat resistance, radiation resistance and other areas as a result of the nanometre-sized dispersion of the inorganic fillers in the organic matrix [6][7][8][9][10]. An immense amount of research and development has been devoted to characterising and understanding the mechanical and physical properties of such nanocomposites.…”

The study deals with thermal and optical properties of poly(methyl methacrylate) (PMMA) containing 2wt% calcium carbonate (CaCO 3 ) nanofiller. It was found that the thermal conductivity increases with increasing temperatures, due to thermal activation of the phonons in the PMMA/CaCO 3 nanocomposite. This enhancement in the thermal conduction is mainly attributed to the heat transferred by lattice vibrations as major contributors and electrons as minor contributors during thermal conduction. The optical properties were investigated as a function of wavelength and photon energy of UV radiation. The optical results obtained were analysed in terms of absorption formula for noncrystalline materials. It was found that the measured optical energy gap for the pure PMMA is greater than the PMMA/CaCO 3 nanocomposite. The width of the energy tails of the localised states was calculated. Adding CaCO 3 nanofiller into PMMA matrix may cause the localised states of different colour centres to overlap and extend in the mobility gap. This overlap may give an evidence for decreasing energy gap when adding CaCO 3 nanofiller in the polymer matrix.
