海面油膜有减弱海浪的作用,这在几个世纪以前就为人们所发现并加以利用.富兰克林最先对此现象作过定性描述.以后,瑞利指出,这种悬浮膜仅是一种单分子层薄膜.本世纪三十年代,朗缪尔和布洛奇特发明了一种技术[1],可将这种悬浮的单分子膜转移到固体表面,形成分子规则排列的单层膜 Sea-surface films have the effect of attenuating waves, which were discovered and exploited centuries ago.Franklin first described this phenomenon qualitatively and later, Rayleigh pointed out that the suspension membrane was only a single molecule In the thirties of this century, Langmuir and Brochente invented a technique [1] that can transfer this suspended monolayer to a solid surface to form a monolayer of molecules regularly arranged
