一些非完全互溶的混合单分子膜会在气-液界面发生相分离现象,形成多种二维微晶畴(Domain)结构,这为人们提供了一个了解与认识准二维混合体系中诸如相变、分相等多种物理过程的机会.同时,混合单分子膜这一结构形式,还提供了一种将多种功能分子组装于同一个单分子层中的方法.因此,对混合单分子膜微观结构的研究与表征具有十分重要的理论及实际意义. Some non-fully miscible mixed monolayers can phase separate at the gas-liquid interface to form a variety of two-dimensional micro-domains (Domain) structure, which provides people with a understanding and recognition of quasi-two-dimensional mixed systems such as phase Change, sub-phase and many other physical processes the same time, the mixed monolayer structure, but also provides a multi-functional molecules assembled in the same monolayer method.Therefore, the mixed monolayer The study and characterization of microstructure has very important theoretical and practical significance.
