In Dr. Liu’s Nanomaterials lab, the synthesis and applications of Carbon Nanofiber (CNF) were explored. CNF has similar applications to the Carbon Nanotube (CNT), however in comparison it is easier to process/functionalize, due to its larger pore size, and is a lower overall cost. Carbon Nanofiber can act as a supercapacitor, facilitating paper based electronics (film transistors, active matrix displays, [...]

Carbon Nanofiber can act as a supercapacitor, facilitating paper based electronics. To explore this further, we fabricated a supercapacitor using CNT, CNF, and manganese oxides. We then characterized their electrochemical properties in a three electrode system. A procedure modeled after a previous experiment was used (http://www.citeulike.org/article/8188780). CNT (fabricated from previous experiments) was added to CNF. [...]
Scanning Electron Microscopy (SEM) was used to view the pore size of the CNF (which was compared to the pore sizes of CNTs). An SEM has a higher resolution than normal microscopes, and images a sample with a high beam of electrons. A comparison of the CNF and CNT images are shown below (the CNT is [...]
