| Abstract | Chemical functionalization of carbon nanotubes (CNTs) and graphite (G) was performed to improve their adhesion to ametal powder (SS316L) and a polypropylene (PP) matrix. A conductive pathway was thus formed to utilize the high electricalconductivity of the SS316L for conductive polymer composites (CPCs) applications. The rheological properties of the feedstockmixture were measured, and samples were formed by injection molding. Fourier transform infrared spectroscopy indicated theexistence of functional groups generated by chemical wet oxidation. Only feedstock mixtures containing more than 28 vol% ofthe PP composite showed a shear rate (102s-1 to 105 s-1), shear viscosity (10 Pa?s to 103 Pa?s), and flow behavior index (n<1)suitable for injection molding. The functionalized composites exhibited improved electrical and mechanical properties over theas-produced composites. The functionalized composites containing 28 vol% PP obtained an electrical conductivity of 6 S/m,compared to 0.5 S/m for the as-produced composites. |
