Fabrication of Patterned Nanofibrous Mats Using Direct-Write Electrospinning

摘要

Due to the numerous advantages of nanofibers, there is a strong demand in various fields for nanofibrousnstructures fabricated by electrospinning. However, the process is currently beset by troublesome limitations with respect tongeometric and morphological control of electrospun nanofibrous mats. This study presents a direct-write electrospinning processnand apparatus with improved focusing and scanning functionalities for the fabrication of various patterned thick mats andnnanofibrous patterns with high geometric fidelity, supported by a number of experimental results. Consequently, variousnpatterned nanofibrous mats were fabricated using the developed method. Additionally, the fabricated mat was successfully usednfor cell patterning as a bioengineering application. The proposed method is expected to significantly improve the properties andnfunctionalities of nanofibrous mats in a variety of applications.
