Abstract

The utilization of organo-modified clays in polymer-clay nanocomposites by the Toyota Research Group of Japan ushered, in a new era in the field of polymer reinforcement, since it was demonstrated that a large increase in the strength and modulus of the composite is possible without decrease in the impact resistance, which is usually observed with polymers filled with silica, calcium carbonate and other inorganic fillers in the micron range [1–3]. Several publications in the field of polymer-clay nanocomposites highlight the research work carried out till date using both plastic and elastomeric matrices [4–9]. The objective of this work is the preparation of sulfur-crosslinked SBR membranes and the incorporation of layered double hydroxides (LDH), in order to improve interfacial interaction and reinforcement between the LDH-SBR nanocomposite. The goal is to develop efficient membranes for the fractionation of organic mixtures by pervaporation. We also proceeded to the characterization of these membranes by Fourier transform infrared spectroscopy (FTIR) and by examination of the surface morphology by scanning electron microscopy (SEM). In addition, swelling tests were carried out to estimate the crosslink density and to assess the qualities of these membranes in terms of pervaporation sorption.
