Abstract

The present work aims to obtain green nanocomposites, derived from a renewable source with benefits in the manufacture and application in aircraft interiors and the advantage of being from a renewable source, with lower production costs, in addition to being environmentally friendly. Thus, poly(furfuryl alcohol) (PFA), a bioresin derived from a renewable source was synthesized and compared with a commercial PFA bioresin, by measures of viscosity, pH, and moisture content. The influence of three carbon nanofillers, graphite nanosheets (GNS), carbon nanotubes (CNTs), and carbon black (CB) in the PFA bioresin were investigated by scanning electron microscopy (SEM), mechanical properties by tensile strength and Izod impact tests, electromagnetic and conductivity measurements. From the results, PFA bioresin showed lower moisture content compared to commercial PFA, enabling to the development of the PFA nanocomposites. PFA nanocomposite with the addition of 2 wt% GNS shows the best dispersion of the nanofiller in the PFA matrix and consequently, effectively improved the Izod impact strength and Young's modulus. However, the PFA nanocomposite with the addition of 2 wt% CNT shows good shielding with the range of 481% higher than neat PFA and the highest electromagnetic interference shielding effectiveness among the studied nanocomposites.
