Biobased hyperbranched poly(ester amide) (HBPEA)/polyaniline (PAni) nanofiber nanocomposites were
prepared by incorporating the as-synthesized PAni nanofiber at varied weight percentages by an ex situ polymerization technique.
Fourier transform infrared spectroscopic analyses indicated the interactions of the benzenoid−quinoid moieties of PAni with
HBPEA. The transition from liquidlike to solidlike behavior of the nanocomposites with a percolation threshold at 10 wt %
nanofiber content was studied using dynamic rheology. The formation of nanofibrous network within the HBPEA matrix as
vouched for by TEM study and initial degradation temperature (from 277 to 307 °C) was found to be increased with the
increment of nanofiber content. The evaluation of mechanical properties such as tensile strength (7.2−12.25 MPa), elongation at
break (88−70%), impact resistance (>100 cm), and scratch hardness (8.5−10 kg) together with the decrease in the sheet
resistance (from 107 to 105 Ω/sq) forwarded the epoxy−poly(amido amine) cured nanocomposites as prospective antistatic
materials.
