液态Wood合金在氢氧化钠电解质溶液中的电毛细变形现象
Electric Current Induced Flow and Electrocapillary Deformation of Liquid Wood Alloy in NaOH Aqueous Solution
摘要
Abstract
The phenomena of the electric current induced flow and electrocapillary deformation for a liquid Wood alloy in a NaOH electrolyte were studied.Electrocapillary behaviors for the liquid Wood alloy in NaOH electrolytes by applying external low voltages were investigated.The electrode reaction (redox reaction) induced the formation or removal of an oxide film,and further caused the drop deformation by decreasing or increasing an interracial tension.The same polar charge in the electric double layer would also decrease the interfacial tension.In order to maintain the stability of system,the contact area of the interface would be expanded,which induces the drop deformation macmscopically.When the liquid metal was charged by the chemical reaction in the solution,the electric field force became an effective way to drive its movement in the electrolyte.关键词
