Research Projects

  • Usages of gel electrodes for cochlear ear implants

    Designing tests and discovering the limitations of using a polymer gel as the electrode for cochlear ear implants rather than the traditional wire electrodes.

    I am currently undertaking research into gel electrodes for cochlear ear implants for my graduate thesis. This research is expected to complete Fall 2014.

  • Formation of PEDOT gel aggregates using gold working Electrodes

    While experimenting with the formation of PEDOT gel for the use of in-situ electrodes for prosthetics, small aggregates were found to be formed when electrochemically polymerizing PEDOT within agaros gel.

    While studying the formation of PEDOT in agarose gel for the use of implanted electrodes, the formation of small crystals were found when gold was used as the working and counter-electrode for the PEDOT Deposition. The crystals were shown to have an alignment in the latitudinal direction and refraction under TEM. Further study and publication to follow at a later date.

  • Tunable Wrinkle Patters through Photo-initialized Polymerization

    Using environmental factors and surface dynamics, tunable wrinkle surfaces were made using a solution of a photoacid generator and furfuryl alcohol.

    Polymer thin films were made using furfuryl alcohol and a Photo Acid Generator, using surface dynamics to cause the internal stresses that form a repeating wrinkle patters. By adjusting environmental conditions, the wavelength of pattern can be changed without affecting the amplitude. The changes in the volume of solution changes the amplitude without affecting the wavelength.

Abstract

Addition of a small fraction of hydrophobic photoacid generator (PAG) to furfuryl alcohol provides a facile route to generate wrinkle topology by acid-catalyzed polymerization that is induced by ultraviolet (UV) light. Here, we describe how the primary characteristic parameters, wavelength and amplitude, of these periodic wrinkles can be tuned through control of the thickness of this furfuryl alcohol–PAG solution prior to UV exposure and the environmental humidity. As the initial coating thickness is increased, the wavelength remains unchanged at fixed temperature and PAG concentration, but the amplitude of the wrinkles increases exponentially with increased coating thickness. A wrinkle to crease transition is observed in some cases as the thickness of the solution coating is increased; this behavior is dependent on the PAG selection. Conversely, variation in relative humidity does not significantly impact the amplitude of the wrinkles, but there is a step change in the wavelength of the wrinkles near approximately 45% relative humidity with a factor of 3 decrease in the wavelength at high humidity. Through this knowledge, we have been able to fabrication wrinkles with an aspect ratio greater than 0.7 in a single step by UV exposure. These simple processing parameters to independently control wavelength and amplitude provide a facile route to systematically examine the role of aspect ratio of wrinkles on physical properties.
