Determining London dispersive surface energy, polar thermodynamic variables, and Lewis acid-base behavior of solid surfaces is crucial in many industrial applications such as adhesion, catalysis, chemical engineering, biomaterials, and technologic processes. Inverse gas chromatography at infinite dilution is a powerful technique that allows the determination of the surface thermodynamic parameters of the interaction between solid materials and organic solvents. In their most recent study, Cho et al. determined the London dispersive surface energy and polar and Lewis acid-base parameters using the Schultz et al. method. These authors committed serious errors and inconsistencies. In this paper, we show the issues made by Cho et al. and proposed a more rigorous model to determine the surface properties of solid materials. Our model using the thermal effect on the surface area of organic molecules was applied on several solid surfaces and showed the various incoherences made by Cho et al. that also neglected the entropic contribution, while it was proved that this contribution is as important as the polar free energy of adsorption.
确定固体表面的伦敦色散表面能、极性热力学变量以及路易斯酸碱行为在许多工业应用中至关重要，如粘合、催化、化学工程、生物材料和工艺过程等。无限稀释反相气相色谱法是一种强大的技术，可用于测定固体材料与有机溶剂之间相互作用的表面热力学参数。在他们最近的研究中，赵等人使用舒尔茨等人的方法测定了伦敦色散表面能以及极性和路易斯酸碱参数。这些作者犯了严重的错误且存在不一致之处。在本文中，我们指出了赵等人所犯的问题，并提出了一个更严格的模型来确定固体材料的表面性质。我们基于有机分子表面积热效应的模型应用于多个固体表面，揭示了赵等人所犯的各种不一致之处，他们还忽略了熵的贡献，而事实证明这种贡献与吸附的极性自由能同样重要。
