Abstract
Both NWs and nanofibers have been subject to much research in present years. A simple method to align and orientate NWs is needed for further research and commercial use. This project intends to utilize NFES, which is a well proven method to direct-write various polymeric solution onto a conducting substrate. NFES a polymer solution with suspended NWs, would embed the NWs into the electrospun fibers. ZnO NWs are grown with a CVD process and suspended in polymer solutions for NFES. Three transfer methods are attempted to suspend and disperse with a high yield and concentration. A NFES setup was used to direct-write the polymer solutions with embedded ZnO NWs onto sputter coated Au quartz plates and Si substrates. The transfer rate in this work was not sufficient to yield polymer solution, with adequate concentration of dispersed ZnO NWs, to construct near field electrospun nanofibers with embedded ZnO NWs.
