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.
Claims26
A composite fiber comprising an array of inorganic nanowires embedded in a polymer matrix, wherein the nanowires have a diameter <100 nm and high aspect ratio of at least 5 with homogenous dispersion and orientation along the fiber axis.
A process for preparation of a composite fiber comprising an array of inorganic nanowires embedded in a polymer matrix, wherein the nanowires have diameter of <100 nm and a high aspect ratio of at least 5 with homogenous dispersion and orientation along the fiber axis, the process comprises:
- contacting nanowires having diameter <100 nm and aspect ratio of at least 5 with a polymer to obtain a mixture comprising nanowires and polymer;
- subjecting the mixture through melt or solution homogenization to obtain uniform distribution and homogenous dispersion of nanowires in polymer matrix;
- and
- subjecting the nanowires in polymer matrix to melt spinning or solution spinning to obtain composite fiber comprising an array of nanowires having diameter <100 nm and aspect ratio of at least 5 oriented along the fiber axis embedded in a polymer matrix.
