Morphology Controlled Electrospun Nanofibers for Humidity Sensor Application

Development of various morphologies such as beads, beaded fibers, and pure fibers, and their potential application for humidity sensor by electrospinning of polymer/composites was described. In order to produce uniform nanofibers with high reproducibility, a controlled current electrospinning system was utilized. It was found that the solution concentration plays a significant role in bead/fiber formation. Furthermore, it can be observed that fiber diameter of beaded-fiber was smaller than pure fiber. It is hopes that by controlling morphology of composites fiber, the optimal condition for obtaining the high performance humidity sensor could be attained.
