Resumo(s): | Commercial multi-walled carbon nanotubes (CNT) were functionalized by oxidation with HNO3, in order to introduce oxygen-containing surface groups, and by thermal treatments at different temperatures for their selective removal. The obtained samples were characterized by adsorption of N2 at -196 ºC, temperature programmed desorption and determination of pH at the point of zero charge. CNT/poly(vinylidene fluoride) composites were prepared using the above CNT samples, with different filler fractions up to 1 %wt. It was found that oxidation reduces composite conductivity for a given concentration, shifts the percolation threshold to higher concentrations and has no significant effect in the dielectric response. |
