Nanocompósitos de matriz polimérica: estratégias de síntese de materiais híbridos
Esteves,Ana Catarina C.; Barros-Timmons,Ana; Trindade,TitoAssociating the well known advantages of hybrid materials to the wide potential of nanomaterials, the new and featuring class of polymer nanocomposites turned into one of the most intensively researched areas. This review highlights recent developments in the field of the synthesis of polymer based nanocomposites. Important issues related to the surface modification of fillers, in order to promote the compatibi...
The synthesis of SiO2@CdS nanocomposites using single-molecule precursors
Monteiro, Olinda C.; Esteves, Ana Catarina C.; Trindade, TitoA chemical method for preparing cadmium sulfide nanocrystals over silica surfaces is reported. This is a one-step synthetic method involving the chemical degradation of alkyldithiocarbamato complexes of cadmium in the presence of submicrometric SiO2 particles. The X-ray powder diffraction patterns of the SiO2@CdS nanocomposites show diffraction peaks consistent with the presence of hexagonal CdS. Visible spectr...
