The dynamic and electrical properties of composites remain a serious concern in application. In this article, 0.1 wt% multi‐walled carbon nanotubes (MWCNTs) are tested to improve the dynamic and electrical properties of three synthesized aromatic poly(amide hydrazides). The inclusion of 0.1 wt% of MWCNTs into these polymer matrices resulted in enhancement of electrical conductivity of nanocomposites compared to unmodified polymer by 10 4 times. Also, an obvious increase of storage modulus, both dielectric constant ( ε ′) and dielectric loss ( ε ″) are enhanced and higher values of complex viscosity are obtained for the novel composites compared to unmodified polymers. FTIR data proved that the inclusion of MWCNTs did not affect the functionalities on the polymer chains. In addition, the dispersion of MWCNTs into bare polymer matrices is studied using transmission electron microscope, scanning electron microscope, and atomic force microscope. POLYM.
