摘要
1基本原理测量表面粘度应该包括以下两部分:(1)LB膜铺在水面上时,该膜和水面相切的方向上每单位面积(如1cm^2)的滑移应力与该膜和水面间滑移速度之比,它表现为LB膜和水面间的表面粘度;(2)一旦有相对运动时,构成LB膜的分子间既有序排列又存在速度梯度,分子间有切应力,也存在粘度。本文采用回转振子法测量表面粘度,其装置如图1所示。
Surface viscosity of some kinds of fatty acid LB film is measured in this paper. The conclusion is that there is linear relationship of surface viscosity and surface pressure. It is a good reference to preparation and study of LB film.
