摘要/Abstract

摘要：

利用润湿角测量仪测量了稳态磁场下去离子水和甘油在有机玻璃表面的润湿角,发现两种液体的润湿角随磁场强度增加而减小. 5T磁场下去离子水和甘油的润湿角分别减小了10.8%和4.0%.分析表明,磁场下润湿角减小源于磁场削弱了液体分子间相互作用从而减小了液体表面张力,进而导致两种液体的润湿性能得到提升.

关键词: 润湿角, 磁场, 分子间作用, 表面张力

Abstract:

Wetting angles of liquids such as deionized water and glycerol on the surface of plexiglass were measured using wetting angle goniometer. It was found that the wetting angles of the two liquids decreased with increasing magnetic field intensity. In the magnetic field of 5 T, decreases of wetting angles of two liquids were up to 10.8% and 4.0%, respectively. The phenomenon was attributed to the weakening of intermolecular interaction in liquids in a magnetic ield, reducing surface tensions of liquids and improving wetability of the two liquids.

Key words: wetting angle, magnetic field, intermolecular interaction, surface tension
