Poly(amide‐hydrazide)s–graphene composites synthesis and characterization

Poly(amide‐hydrazide)s copolymers were prepared using hydrazide derivative of phenylene diamine to react with aromatic diacid chloride. The wholly aromatic poly(amide‐hydrazide)s have better solubility in organic polar solvents, such as N,N‐dimethylacetamide, dimethylsulfoxide, 1‐methyl‐2‐pyrollidone, and N,N‐dimethylformamide, at room temperature, while still maintaining their high thermal stability. Graphene in the nano size was used as a filler to enhance their thermal and mechanical properties. The polymers as well as the composite were characterized by spectral and mechanical tools as well as by X‐ray analysis. POLYM. COMPOS., 38:1311–1318, 2017. © 2015 Society of Plastics Engineers
