Abstract Scope |
Electrospinning is an exciting method for the production of fibers using an electric field to pull charged threads from polymer solutions. The size of these fibers is in the range of 100-1000 nm. Fibers are collected as bulk fiber meshes/mats. By their nature, these materials have very high surface to volume ratios – a characteristic historically exploited for filtration applications. Additionally, production of fibers directly from a liquid solution allows for fine control and tuning of fiber mat properties through adjustment of spinning parameters and solution composition including applied electric field, solution feed rate, viscosity, surface tension, conductivity and molecular weight. Here we explore the effect of these parameters on fiber spinnability and characteristics, such as morphology and microstructure. Including precursors in solutions can facilitate conversion of nanofibers after electrospinning, such as ceramic nanofibers through furnace treatments. Our group is particularly interested in filtration, sensing and biomedical applications. |
