In this letter, we report on a technique for the hierarchical assembly of nanofibers into
crossbar nanostructures. An electrospinning process is used to create polymer-based
nanofibers with diameters ranging from 10–180 nm and lengths of up to several centimeters.
By controlling the electrostatic field and the polymer rheology, the nanofibers can be
assembled into parallel periodic arrays. We also propose a theoretical model for the
process.© 2003 American Institute of Physics. DOI: 10.1063/1.1544060 Nanofibers …
