摘要
用布儒斯特角显微镜研究了花生酸分子成膜过程中单分子膜表面形貌的动态变化,发现在气/液界面上花生酸分子首先形成岛状分布,随着表面压的增加形成完整的单分子膜,而当表面压达到崩溃压后薄膜出现裂纹,分子膜重叠,形成多层膜。分析了花生酸单分子膜的形成机理。
Dynamic domains morphology of arachidic acid monolayer were researched by Brewster angle microscopy （BAM）. The results indicate that arachidic acid molecules distribute randomly just as insular domain originally during the formation process of the monolayer at an air/liquid interface, then they are shaped into a whole condensed monolayer with the increase of surface pressure. The monolayer is cracked at the collapse pressure, then they overlap and form a multilayer. The mechanism for this process was analyzed briefly.
