Aromatic polyamide hydrazides are considered one of high performance polymers. They possess high thermal stability and good mechanical properties. These polymers are considered as insulating ones. By inclusion of 0.1 Wt. % MWCNTs into polymer matrices. We found that, there is a slight difference in thermal stability of the composites compared to bare polymers, for electrical properties the novel composites conductivities get enhanced by 10⁴ orders of magnitude and converted from insulation polymers to semi conducting ones. For dynamic properties we found an enhancement in storage modulus and complex viscosity also there is a slight shift to higher values of hypothetical Tg of the composites compared to bare polymers. Finally the surface morphology of the novel composites was studied using TEM, SEM and AFM
