Kinetics of Air Bubble Growth on a Silicon Substrate in Alcohol and Water-Alcohol Media

摘要

The spontaneous growth of sessile air bubbles with sizes of 1 mm and below on a solid surface has been experimentally studied in ethanol and its aqueous solutions under constant external conditions (atmospheric pressure and a temperature of 20 degrees C). A noticeable growth of bubble volume has been observed for at least 2 h in ethanol solutions beginning from an alcohol concentration of 50%. The time dependences of bubble volume have different patterns in ethanol solutions and undiluted alcohol.
