Research on the Surface Potential of Water Evaporation Retardants
Surface potential is an important way to study the nature of Langmuir monolayer, this paper mainly introduces the definition and the models of the surface potential; sums up some research progress and application at home and abroad, it also explores the important significance of the potential surface in water evaporation retardant, that is, when the monolayer is interfered with the natural environment such as the wind, dust, rain, temperature and so on, these will cause the water body surface monolayer to be destructed, reduce its stability, or even lose its effect of water evaporation retardant. The structure, composition and changes of the monolayer and the spreadability and reparation of the film can be tracked and observed by measuring the surface potential. Then it can contribute significantly to the promotion and application of water evaporation retardant.
