Abstract

This paper reports a novel and cost-effective approach which enables the integration of nanostructures and micropatterns. In this work nanofibers are selectively patterned in defined micropatterns via a collector chip. The driving momentum of the micropattern formation, namely the non-uniform electrical field, is studied by finite element method. Micropatterned nanofiber mats are successfully fabricated. The SEM characterization demonstrates that the microstructures are manifested by distinct porosities and thicknesses. This work opens a door for a broad array of applications such as nanoelectronics and tissue engineering, where the fibrous materials with the characteristic features sizes over several order of magnitudes are required.
