Abstract Isotactic polypropylene (iPP) and multi-walled carbon nanotubes (MWNTs) composites were manufactured by melt blending and its thermal behavior and rheological properties were investigated. The results show that the melting temperature, complex viscosity, storage modulus (G′) and loss modulus (G″) of iPP/MWCNTs composites are higher than that of pure iPP. Moreover, the complex viscosity of iPP and iPP/MWCNTs composites decreases with the increase of frequency, showing an obvious phenomenon of ‘shear thinning’ and a pseudo-plastic fluid behavior. iPP and iPP/MWCNTs products were, respectively, prepared via injection molding technology. X-ray test results show that the crystallinity of iPP and iPP/MWCNTs composite products is constant, and its values do not change significantly with the increase of depth. Moreover, the overall orientation value of iPP/MWCNTs composite products is relatively higher and decreases gradually with the increase of depth. The tensile test results show that, compared with the pure iPP products, the tensile strength and modulus of iPP/MWCNTs composite products are greatly increased, and the elongation at break and toughness are obviously reduced.
