Aromatic poly(1,3,4-oxadiazole)s (PODs) are known to have excellent thermal, chemical, and hydrolytic stability. For this reason, PODs have been used as fibers, films, and membranes. Recently, carbon nanomaterials such as carbon nanotube, graphene, and their derivatives have been considered as ideal reinforcing nanoscale fillers because of their superior tensile modulus, strength, electrical conductivity, thermal and chemical stability, as well as large surface area and aspect ratio. Especially, the combination of 1D and 2D allotropes of carbon nanomaterials has attracted great interests with the properties expected to exceed the respective single one because of their synergistic effect. In the present study, we have manufactured a series of POD/MWCNT/graphene hybrid nanocomposite films by using a solution-mixing and have investigated their structures, electrical property, thermal stability, and mechanical property as a function of the relative content of pristine MWCNT and graphene. |
