一、概况LB 膜是一种单分子膜,它是人为地利用分子间相互作用而建立起来的分子体系,其分子排列均匀、致密、有序。关于这种单分子膜的研究,起自于十九世纪末。而对 LB 膜进行系统的物理、化学的研究是1917年 langmuir 采用膜天平才开始的。他测量了分子的大小、形状和取向,膜的表面积和张力等,并且和 Blogett 合作,成功地将液面的单分子膜转移到了固体表面上。1932年, I. Overview LB film is a monolayer, which is artificially made use of the molecular interaction established molecular system, the molecular arrangement of uniform, dense and orderly. The study of this monolayer began in the late 19th century. The physical and chemical study of the LB film started with the 1917 langmuir film balance. He measured the size, shape and orientation of the molecules, the surface area and tension of the membrane, and he worked with Blogett to successfully transfer the liquid monolayer to a solid surface. In 1932,
