Resumo
The advancement of technology has demanded the development of materials
with increasingly lighter and more resistant properties. The development of
nanocomposites first started in the mid-80s and contributed for obtaining materials
with excellent properties. In this work, Green Lake clay was organophilized
and incorporated into a commercial homopolymer polypropylene. The efficiency
of organophilization was confirmed by water swelling analysis and, later, by Xray
diffraction (XRD) analysis. Composites at 0.5, 1.0 and 2% by weight of
clay/polypropylene were prepared by double screw extrusion. The properties of the
composite were evaluated by means of Charpy impact resistance, tensile strength at
rupture, thermogravimetric analysis (TGA). Crystallinity index was determined by
differential scanning calorimetry (DSC). The organophilization processwas efficient,
the thermogravimetric analysis showed that there was no decrease in the thermal stability
of the composites when compared to pure polypropylene, and the results of
the Charpy impact resistance were equivalent when compared to the commercial
nucleant composites.
