  Abstract

Polyamide 66/graphene (PA66/GN) nanocomposite fibers were fabricated using solid-state shear milling (S3M) and melt-spinning. Furthermore, the effects of various S3M cycles and GN loadings on the crystallinity and physicalmechanical properties of PA66 fibers were investigated. The nanocomposite fibers show excellent dispersion and interfacial interaction between GN sheets and the PA66 matrix. This is ascribed to the strong 3D shear force generating the chemical bond (-C-O-C-) between the GN and PA66, so that GN is uniformly dispersed in the PA66 matrix. The mechanical property of PA66/GN nanocomposite fiber prepared via the S3M method is better than those obtained by conventional blending at the same loading. The incorporation of GN into PA66 improves the crystallizing temperature, crystallinity, and thermal stability. The tensile strength of 10-S3M-0.3 wt% nanocomposite fiber reaches a maximum (940 MPa), which is improved by 26.7 % compared to the PA66 fiber.
