Vapor grown carbon nanofibers (VGCNFs)-reinforced polyimide (PI) composites were synthesized by in-situ polymerization of monomers in the presence of sonication. PI was prepared by reacting the diamine with commercially available dianhydrides, such as 3,3',4,4'-benzophenone tetracarboxylic dianhydride (BPDA) and 4,4'-oxydianiline (ODA) and the VGCNFs contents were varied from 1 to 10 wt.% in the polymer matrix. The electrical and transparent properties of the composite films were characterized by specific volume resistivity and XRD. From the experimental results, we confirmed that VGCNFs were well-dispersed in the polymer solution and the resulting VGCNFs/PI composite films were electrically conductive and optically transparent with significant increase in conductivity at a low VGCNFs loading. |
