CARRIAZO, J. G.; TORRES, J. A. y ENSUNCHO, A. E.. STUDYING THE INTERCALATION OF POLYANILINE IN CLAY MINERALS TO MAKE MICRO-COMPOSITES MATERIALS. rev.udcaactual.divulg.cient. [online]. 2012, vol.15, n.2, pp.481-489. ISSN 0123-4226.
This paper reports a study of the polyaniline-species intercalation into two clay minerals to form micro-composite materials with properties for electron transport. The solids were prepared by "in situ" synthesis of polyaniline into the matrix of two Colombian montmorillonite-clay types. The materials were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrical resistance measurements. An irregular grain morphology for composite materials was observed by SEM, and the intercalated/ delaminated structures were verified by XRD analyses. The potential performance of some of the solids to be current conductors was confirmed by electrical resistance measurements, which also gave additional information on the possible distribution and configuration of the constituting phases of polyaniline/montmorillonite composites.
