1. Study of the potencial of national and argentinean bentonites to obtasin organophilic bentonites in aqueous dispersion and semi-solid medium to be applied in polymer nanocomposite / Estudo do potencial de bentonitas nacionais e argentinas na obtenção de bentonitas organofilicas em dispersão aquosa e meio semi-solido visando a aplicação em nanocompositos polimericos
Seven bentonites were evaluated to verify the potential to obtain the organophilic clay. The characterization by X-ray diffraction to evaluate the basal spacings was made, as well as the characterization by swelling capacity test, in water and in xylene, to evaluate the hydrophilic and organophobic character, by X-ray dispersive energy to indentify the prese

2. Estudo das propriedades de nanocompositos de polipropileno/polipropileno grafitizado com anidrido maleico e montmorilonita organofilica
The study of nanocomposites, object of this project, was divided in two independent experimental parts. In the first esperimental part the obtention of organophilic montmorillonite from the cation xchange of a Na-montmorillonite for cations of quaternary hexadecyl trimethyl ammonium bromide, in aqueous solution, to prepare polymeric nanocomposites was studie
