| Summary: | 碩士 === 國立清華大學 === 材料科學工程學系 === 96 === Surface tension of silicon wafer decorated with NH3-containing single-walled carbon nanotube films (SWNTFs) is controllable by electric as well as magnetic fields. Field modulated contact angle and droplet migration are characterized and surface tensions of pristine and decorated nanotube films are calculated from experimental data by Owens-Wendt Model.
The electro-wetting (DI-water and ethylene glycol) on SWNTF is studied upon external magnetic field. Feasible mechanism is proposed and surface tensions are calculated based on experimental data using Owens-Wendt Model and Young’s Equation. Finally, we propose an model to explain the surface tension of closed tubes.
