Abstract
Nanofibers are fabricated by introducing a mixture of a polymer solution and inorganic precursor into a dispersion medium and shearing the mixture. Liquid strands, streaks or droplets of the mixture are spun into elongated fibers that include inorganic fibrils. The resulting composite inorganic/polymer fibers may be provided as an end product. Alternatively, the polymer may be removed to liberate the inorganic fibrils, which may be of the same or smaller cross-section as the polymer fibers and may be provided as an end product.
