摘要

The objective of this work is to evaluate the effect nanoclays inclusion on copolymer of Styrene-Ethylene-Propylene-Styrene (SEPS) at two compositions of nanoclay (0 and 3%, w/w). The resulting nanoclay was characterized by XPvD, SEM, EDX. Membranes modified with nanoclay were studied by water uptake, porosity and DSC analysis. The XRD patterns indicated that both samples of nanoclays, obtenied of cosmetic and molding clay, were suitable for the modification because of the increasing of the polymer-nanoclay surface area after this procedure. SEM analysis revealed an agglomeration phenomenon after contacting the surfactant-modified nanoclays with air. The incorporation of surfactant hydrocarbon chains in the MMT structure was confirmed by the EDX results. Finally, DSC analysis showed good stability of modified membranes at temperature changes, suggesting that this material could be used in applications that require temperatures range less than 150 °C.
