N2  - Three different hydrazide/amide copolymers were prepared and showed  good thermal characteristics. The copolymers also exhibited a degree of  crystallinity which could enhance their mechanical properties. Applying carbon  nano-tubes to the copolymers did not improve their characteristics; however  when the carbon nano tubes were functionalized by treatment with hydrogen  peroxide; their attachment with polymers increased and an improvement in the  thermal and mechanical characteristics was observed. The obtained composites  are therefore good potential candidates for the production of high thermal and  mechanically strong fibers which could be used for several industrial and  military applications.  Applying Graphene to the copolymers improves their characteristics (the  thermal and mechanical characteristics) in the low percent (0.1%)
