dc.description.abstract | In this study, polycaprolactam (PA6) nanocomposites with thermally reduced graphene oxide (TrGO) and
carbon nanotubes (CNTs) were prepared by melt blending with the aim of obtaining films with improvements
in permeability (oxygen and water vapor), mechanical properties and electrical conductivity.
The permeability to water vapor and oxygen of the nanocomposites containing TrGO significantly
decreased with increasing filler load due to a more tortuous path to gas permeation. For CNT nanocomposites,
low barrier properties were found. The tensile tests showed similar behavior in both cases,
with somewhat higher elastic modulus for TrGO compounds. CNT gave higher electrical conductivity to
polyamide with lower percolation threshold; however this conductivity reached a constant value around
10 wt% of filler. The conductivity of TrGO nanocomposites was lower, probably due to the presence of
impurities in its structure; however, the property increased up to 15 wt% of filler load without evidence
of stabilization at this concentration. | |
