MORELLI, Fernanda C.  e  RUVOLO FILHO, Adhemar. Nanocomposites of polypropylene and organophilic clay: X ray diffraction, absorption infrared spectroscopy with fourier transform and water vapor permeation. Polímeros [online]. 2010, vol.20, n.2, pp.121-125.  Epub 07-Maio-2010. ISSN 0104-1428.  https://doi.org/10.1590/S0104-14282010005000014.

In this work nanocomposites were prepared from polypropylene, graft polypropylene with maleic anhydride as compatibilizer and organophilic montmorillonite Cloisite 20A with concentrations of 1.5, 2.5, 5.0 and 7.5% clay. The mixture was made in the melt state using a twin screw extruder. The materials were characterized by X ray diffraction, infrared spectroscopy with Fourier transform and analysis of water vapor permeation. The results of X ray diffraction and absorption infrared spectroscopy indicates the formation of nanocomposites with structures probably exfoliate and / or intercalated for concentrations of 1.5 and 2.5% clay, and provided a marked decrease in the water permeability, corroborating with other analyses.

Palavras-chave : Nanocomposites; polypropylene; water vapor permeability; montmorillonite clay.
