have found many applications over the past couple of
decades, but existing fabrication methods can only make very short
nanowires. We present a new method for making very strong, flexible,
and centimeter long nanowires on polymer nanofibers. Single nanofibers
of poly(m-phenylene isophthalamide) with diameters
in the range of 300–600 nm were prepared by electrospinning
onto a rotating collector. These nanofibers were coated coaxially
with a variety of metals and insulators to illustrate the materials
generality of the methodology. The flexibility and compatibility with
high-temperature deposition conditions (up to 350 °C) offered
by this nanofiber scaffold pave the way for future nanowire applications
enabled by increased lengths.
