| Abstract: | We have investigated the transient pore dynamics in a chemically destabilized liquid membrane in buffer solutions at macroscopic scale. A hole opened and closed repeatedly in response to pH in the surrounding media when the concentration of surfactant in the liquid membrane was sufficiently high to form emulsion at equilibrium and the membrane was larger than a critical value. The analysis of pore dynamics allowed us to estimate some physicochemical properties such as membrane tension, line tension, and membrane viscosity. |
