  • Publication number: 20220403167
    Abstract: The disclosure describes composite fibers reinforced with inorganic nanostructures of high aspect ratio with homogeneous dispersion and alignment along the fiber axis and a process for producing said composite fibers. A composite fiber comprising an array of inorganic nanowires embedded in a polymer matrix. The nanowires have a diameter <100 nm and high aspect ratio of at least 5 with homogenous dispersion and polymer chains of the polymer matrix and the nanowires are oriented along the fiber axis. The nanowire wt % in the composite fiber is in the range of 0.01 to 2 wt %. The inorganic nanowires are non conducting and include at least one of ZnO, or aluminosilicate clay tubes.
