Source abstract
Abstract
Nanocomposites based on polyamide 6,6 and carbon nanofiber have been obtained following a new procedure. It consists of the physical mixing of the polymer matrix, in the form of powder, and the corresponding amount of additive. Then, samples were prepared by compression molding and their structural characteristics, as well as their thermal and electrical properties were determined. The materials present good electrical conductivity at lower percolation thresholds than those corresponding to systems prepared by melt mixing. The study was carried out with two different grain sizes, and the findings are discussed in terms of the different size ratios of polymer to carbon nanofiber.
