We report a novel, economical method of preparing well‐aligned and well‐oriented nanoribbons made of poly(vinyl alcohol) (PVA). The method requires no special equipment and easily produces nanoribbon. The structure of uniaxially drawn nanoribbon was investigated by polarized microscopy, polarized FT‐IR, and X‐ray diffraction, which showed high molecular and crystallite orientations. The well‐aligned PVA nanoribbon, measuring several tens of micrometer width and around 400 nm thickness, had a Young's modulus of 9 GPa and a tensile strength of 350 MPa.
