【 摘 要 】

Chemical modification of clays is possible dueto their ion-exchange and adsorption capacities, which allows the adjustmentof the physicochemical properties of the surfaces of their layers. This modificationmakes possible the use of clays to produce a great number of new materials,which range from coarse applications such as oil based drilling fluids to refinedapplications such as pharmaceutical products. This article intends to exposewhere there is still space for research and investment aiming at the performanceimprovement of clay-based materials.
