Abstract

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°С). 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.

酒精和水-酒精介质中硅基板上气泡生长的动力学

摘要

在恒定的外部条件（大气压力和 20°С 的温度）下，已经在乙醇及其水溶液中对固体表面上尺寸为 1 毫米及以下的固着气泡的自发生长进行了实验研究。从 50% 的酒精浓度开始，在乙醇溶液中至少 2 小时观察到气泡体积的显着增长。在乙醇溶液和未稀释的酒精中，气泡体积的时间依赖性具有不同的模式。
