Adsorption-desorption of Hydrogen Bonding Fluid Confined in a Spherical Cavity：the Role of Surface Regulation
摘要
Abstract
The effect of surface regulation on the phase behavior of hydrogen bonding( HB) fluid confined in a nano-spherical cavity was investigated by phase equilibrium thermodynamics. We tried to reveal the important role of cavity surface playing in the adsorption-desorption transition of confined HB fluid when the fluid-surface interaction is a square-well potential. In this study, density functional theory for classical fluids was used together with the modified fundamental measure theory. It was found that the cavity surface could give rise to significant effects on the critical temperatures, critical densities and phase regions of layering transition and capillary condensation. As a result, one can regulate the phase equilibria and aggregated state of the HB fluid by changing the strength and range of fluid-surface interaction and the radius of spherical cavity. It is expected that the present study is helpful to design related adsorption materials or to study the phase behavior of nano-fluids.关键词
