| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 102 === The research is to study voltage distribution of Stern Layer by simulation and experiment. For simulation, we chose flow, chemical and electrical models in steady state and computed with software CFD-ACE+ . For experiment, Atomic Force Microscope(AFM) is used, because of extremely small size of stern layer(Nanometer or Angstrom), in order to get accurate force curve, we made many measurements in different concentrations of electrolyte by probe, and discussed the forces(Van der waals force and Electrostatic force) acting on probe in liquid, then transform force curve to voltage curve.
From the experimental results in seven concentrations, the thickness
of stern layer are almost same(About 0.5nm), and diffusion layer are 1.75~8.89nm, voltage of electrode surface are 54.94~105.04mV, Zeta Potential are 16.88~38.23mV which have same region(Below 80nm) with many relevant Literatures.
