离子表面活性剂体系中和频光谱检测方案(其它光谱仪)

Surface active agents, shortly referred to as surfactants, tune the air-water interface with respect to both its equilibrium and dynamic properties. On a macroscopic scale, the formation of foam is the most prominent characteristic of a surfactant solution. It takes place when subjecting an aqueous solution to mechanical deformation.Prime motivation of the research presented in this thesis is to obtain a better understanding ofair-water interfaces on a molecular scale and to relate this knowledge to colloidal systems which are naturally determined by an unusual ratio of surface to volume. In particular, this thesis aims for an understanding of the relationship between the microscopic structure of an adsorption layer and the molecular structure of its constituent molecules. Moreover, relating the microscopic properties of an interface to the macroscopic behavior of a system is a major objective.
