摘要: 考虑到吸附膜与单分子不溶膜的相似性,在不溶膜研究中引入分子间相互作用参数β,用以讨论不溶膜中的非理想性问题。对“6201”/C18SO4Na体系得到了一个与临界值2.0接近的β值,进一步验证了该体系存在相分离的推测。

Abstract: In consideration of the similarity of insoluble monolayers and soluble monolayers,amolecular interaction parameter(β)was introduced to describe the nonideality of the mixedinsoluble monolayers. From the surface pressure-area isotherms of “6201”/C18SO4Na mix-tures,a high molecular interaction parameter which was closed to the critical value 2.0 wasobtained,which has further verified the previous guess that a phase separation took place ata higher surface pressure.

Key words: Insolube monolayers, Intermolecular interaction parameter, Nonideality, Sur-factant
