  • Parametric optimization of micro-contact printing based thermal transfer of electrospun Nanofibers
    Microelectronic Engineering, 2010
    Co-Authors: Emilie Secret, Haoli Zhang, Li Wang, Yong Chen
    Abstract:

    We report on the results of a parametric optimization of micro-contact printing based thermal transfer of electrospun Nanofibers. Fiber electrospinning was performed with a solution of thermoplastic polymer and a collector having a rectangular open area. After electrospinning, a piece of elastomer polydimethylsiloxane (PDMS) was used to scratch Nanofibers from the open area and to thermally transfer them to the surface of a glass substrate by micro-contact printing at a temperature slightly higher than the glass transition temperature of the polymer. With the help of optical measurements, we optimized the printing conditions including the temperature and printing duration. Then, the stability of the transferred Nanofibers was studied with sonication at different power rates. As expected, the printed Nanofibers showed a much enhanced adhesion stability, comparing to the as-Deposited Nanofibers. Furthermore, the Nanofibers after thermal transfer could be used for patterning by using conventional photolithography and reactive ion etch techniques.

  • microcontact printing and lithographic patterning of electrospun Nanofibers
    Langmuir, 2009
    Co-Authors: Lei Wang, Yuan Chen
    Abstract:

    We describe a method for printing electrospun Nanofibers from a collector onto another substrate. The electrospinning collector that we used is made of a thin layer of polydimethylsiloxane (PDMS) on glass with or without patterned electrodes, allowing the fabrication of either aligned or randomly Deposited Nanofibers. Afterwards, the electrospun fibers are printed onto a glass substrate, and such a process can be repeatedly used to obtain multilayer fibers with a good reproducibility. We also show a postprocessing method for the pattern formation of electrospun Nanofibers by using standard photolithography and reactive ion etching techniques, thereby providing a way of fabricating microarrays of single fibers or distributed fiber matrices.
