| Abstract Scope |
Compared with pristine polymers the clay/polymers nanocomposites usually present better properties. Bentonites, only beneficiated or modified with organic surfactants, are the industrial clays with more potential for use as fillers in polymer nanocomposites for the replacement of metals. So it is forecasted that the bentonites will be in a near future important fillers in clay / polymer nanocomposites to be used in the oil and gas industry for the replacement of metal components. In this work a Brazilian "chocobofe" bentonite was beneficiated and modified with the surfactant, trimethylhexadecyl ammoniun chloride. The pristine and the organophilic clays were characterized by techniques such as XRD, DTA/TGA, SEM, BET surface area, IR, cation exchange capacity and swelling in organic solvents and had evaluated its potential use as nanofillers for natural rubber. Improvement of 100% was obtained for the rupture strength, with no severe diminution of the elongation (with 10 pcr organophilic clay). |
