In this paper, epoxy resin-based monolayers (ER monolayers) were prepared as water evaporation retardants. The interfacial stability performances of molecular films on resisting disruption of temperature and wind were investigated. The dependence of evaporation resistance on temperature was explicit and supported. Energy barrier theory was performed to explain the retardation mechanism of water evaporation of ER monolayers. The disruption of wind on monolayers was researched through simulation of surface waves over the subphase water. The results showed that ER monolayers presented better stability to resist disturbances of temperature shift and surface waves compared to C16OH monolayer. ER monolayers had a good effect on retardation of water evaporation due to their ability to spread spontaneously and form closely packed films over the water surface.
Graphical abstractPlot of the evaporation resistance of C16OH and ER monolayers as a function of action time of the vertical vibration. The amplitude of the vertical vibration is 2 mm. The vibration frequency is 30 Hz. The temperature of subphase water is 303 K.Figure optionsDownload full-size imageDownload as PowerPoint slide
