1. CompÃsitos de Poli (Metacrilato de Metila) / nanofolhas de grafite: preparaÃÃo, caracterizaÃÃo e efeitos radiolÃticos / Nanocomposites of Poly (Methyl Metacrylate)/Graphite nanosheets: Preparation, Characterization and Radiolytic Effects
Nowadays there is a great interest in the preparation of PMMA/graphite composites, el ther in graphite powder or in nanosheet forms. They are used mainly in the production of conducting composites. In this work graphite nanosheets were obtained by chemical intercalation using H2SO4 and HNO3. After this treatment, the intercalated graphite (GIC) is put into a

2. NanocompÃsito montmorilonita/polipirrol: preparaÃÃo,caracterizaÃÃo e aplicaÃÃo como sensores de volÃteis
Clay/polymer nanocomposites have been sufficiently studied during some time because they could be used in industrial applications. Clay is a Phyllosilicate Subclass Mineral, it is formed by sheets, layers or lamels and has a Tetrahedron- Octahedron-Tetrahedron (TOT) like structure with free hydroxile and cations between the lamels and on the surface. In this

3. Nanocomposite polymer electrolytes based on poly(oxyethylene) and cellulose whiskers
Solid lithium-conducting nanocomposite polymer electrolytes based on poly(oxyethylene) (POE) were prepared from high aspect ratio cellulosic whiskers and lithium imide salt, LiTFSI. The cellulosic whiskers were extracted from tunicate -a sea animal- and consisted of slender parallelepiped rods that have an average length around 1 µm and a width close to 15
